+
+## 安装
+
+使用 npm:
+
+```bash
+$ npm install axios
+```
+
+使用 bower:
+
+```bash
+$ bower install axios
+```
+
+使用 yarn:
+
+```bash
+$ yarn add axios
+```
+
+使用 cdn:
+
+```html
+<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
+```
+
+## 例子
+
+### 注意: CommonJS 的使用
+
+为了能够获得TypeScript编码的智能感知和自动补全，使用CommonJS imports的时候，用以下的方式使用`require()` 
+
+```js
+const axios = require('axios').default;
+
+// axios.<method> 现在可以提供自动补全和参数输入
+```
+
+执行一个 `GET` 请求
+
+```js
+const axios = require('axios');
+
+// Make a request for a user with a given ID
+axios.get('/user?ID=12345')
+  .then(function (response) {
+    // handle success
+    console.log(response);
+  })
+  .catch(function (error) {
+    // handle error
+    console.log(error);
+  })
+  .finally(function () {
+    // always executed
+  });
+
+// Optionally the request above could also be done as
+axios.get('/user', {
+    params: {
+      ID: 12345
+    }
+  })
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  })
+  .finally(function () {
+    // always executed
+  });  
+
+// Want to use async/await? Add the `async` keyword to your outer function/method.
+async function getUser() {
+  try {
+    const response = await axios.get('/user?ID=12345');
+    console.log(response);
+  } catch (error) {
+    console.error(error);
+  }
+}
+```
+
+> **NOTE:** `async/await` is part of ECMAScript 2017 and is not supported in Internet
+> Explorer and older browsers, so use with caution.
+
+执行一个 `POST` 请求
+
+```js
+axios.post('/user', {
+    firstName: 'Fred',
+    lastName: 'Flintstone'
+  })
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  });
+```
+
+执行多个并发请求
+
+```js
+function getUserAccount() {
+  return axios.get('/user/12345');
+}
+
+function getUserPermissions() {
+  return axios.get('/user/12345/permissions');
+}
+
+axios.all([getUserAccount(), getUserPermissions()])
+  .then(axios.spread(function (acct, perms) {
+    // Both requests are now complete
+  }));
+```
+
+## axios API
+
+同样的道理，你可以通过传递相关的配置来发送请求`axios`.
+
+##### axios(config)
+
+```js
+// Send a POST request
+axios({
+  method: 'post',
+  url: '/user/12345',
+  data: {
+    firstName: 'Fred',
+    lastName: 'Flintstone'
+  }
+});
+```
+
+```js
+// GET request for remote image
+axios({
+  method: 'get',
+  url: 'http://bit.ly/2mTM3nY',
+  responseType: 'stream'
+})
+  .then(function (response) {
+    response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))
+  });
+```
+
+##### axios(url[, config])
+
+```js
+// Send a GET request (default method)
+axios('/user/12345');
+```
+
+### Request 方法的别称
+
+所有支持的方法都有通俗易懂的别称
+
+##### axios.request(config)
+
+##### axios.get(url[, config])
+
+##### axios.delete(url[, config])
+
+##### axios.head(url[, config])
+
+##### axios.options(url[, config])
+
+##### axios.post(url[, data[, config]])
+
+##### axios.put(url[, data[, config]])
+
+##### axios.patch(url[, data[, config]])
+
+###### 注意
+
+当你使用方法别称的时候， `url`, `method`, 和 `data` 等属性都不需要在配置中指定。
+
+### 并发
+
+解决并发请求的帮助函数
+
+##### axios.all(iterable)
+
+##### axios.spread(callback)
+
+### Creating an instance
+
+你可以使用新的axios的实例创建一个自定义的配置
+
+##### axios.create([config])
+
+```js
+const instance = axios.create({
+  baseURL: 'https://some-domain.com/api/',
+  timeout: 1000,
+  headers: {'X-Custom-Header': 'foobar'}
+});
+```
+
+### 实例的方法
+
+下面是可以应用到的实例方法。这些指定的配置都可以被合并到实例的配置中。
+
+##### axios#request(config)
+
+##### axios#get(url[, config])
+
+##### axios#delete(url[, config])
+
+##### axios#head(url[, config])
+
+##### axios#options(url[, config])
+
+##### axios#post(url[, data[, config]])
+
+##### axios#put(url[, data[, config]])
+
+##### axios#patch(url[, data[, config]])
+
+##### axios#getUri([config])
+
+## 请求配置
+
+这些是用于发送请求的可用配置项。只有 `url`是必须的。如果 `method`没有被指定的话，Requests默认是`GET`.
+
+```js
+{
+  // `url` is the server URL that will be used for the request
+  url: '/user',
+
+  // `method` is the request method to be used when making the request
+  method: 'get', // default
+
+  // `baseURL` will be prepended to `url` unless `url` is absolute.
+  // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
+  // to methods of that instance.
+  baseURL: 'https://some-domain.com/api/',
+
+  // `transformRequest` allows changes to the request data before it is sent to the server
+  // This is only applicable for request methods 'PUT', 'POST', 'PATCH' and 'DELETE'
+  // The last function in the array must return a string or an instance of Buffer, ArrayBuffer,
+  // FormData or Stream
+  // You may modify the headers object.
+  transformRequest: [function (data, headers) {
+    // Do whatever you want to transform the data
+
+    return data;
+  }],
+
+  // `transformResponse` allows changes to the response data to be made before
+  // it is passed to then/catch
+  transformResponse: [function (data) {
+    // Do whatever you want to transform the data
+
+    return data;
+  }],
+
+  // `headers` are custom headers to be sent
+  headers: {'X-Requested-With': 'XMLHttpRequest'},
+
+  // `params` are the URL parameters to be sent with the request
+  // Must be a plain object or a URLSearchParams object
+  params: {
+    ID: 12345
+  },
+
+  // `paramsSerializer` is an optional function in charge of serializing `params`
+  // (e.g. https://www.npmjs.com/package/qs, http://api.jquery.com/jquery.param/)
+  paramsSerializer: function (params) {
+    return Qs.stringify(params, {arrayFormat: 'brackets'})
+  },
+
+  // `data` is the data to be sent as the request body
+  // Only applicable for request methods 'PUT', 'POST', and 'PATCH'
+  // When no `transformRequest` is set, must be of one of the following types:
+  // - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams
+  // - Browser only: FormData, File, Blob
+  // - Node only: Stream, Buffer
+  data: {
+    firstName: 'Fred'
+  },
+  
+  // syntax alternative to send data into the body
+  // method post
+  // only the value is sent, not the key
+  data: 'Country=Brasil&City=Belo Horizonte',
+
+  // `timeout` specifies the number of milliseconds before the request times out.
+  // If the request takes longer than `timeout`, the request will be aborted.
+  timeout: 1000, // default is `0` (no timeout)
+
+  // `withCredentials` indicates whether or not cross-site Access-Control requests
+  // should be made using credentials
+  withCredentials: false, // default
+
+  // `adapter` allows custom handling of requests which makes testing easier.
+  // Return a promise and supply a valid response (see lib/adapters/README.md).
+  adapter: function (config) {
+    /* ... */
+  },
+
+  // `auth` indicates that HTTP Basic auth should be used, and supplies credentials.
+  // This will set an `Authorization` header, overwriting any existing
+  // `Authorization` custom headers you have set using `headers`.
+  // Please note that only HTTP Basic auth is configurable through this parameter.
+  // For Bearer tokens and such, use `Authorization` custom headers instead.
+  auth: {
+    username: 'janedoe',
+    password: 's00pers3cret'
+  },
+
+  // `responseType` indicates the type of data that the server will respond with
+  // options are: 'arraybuffer', 'document', 'json', 'text', 'stream'
+  //   browser only: 'blob'
+  responseType: 'json', // default
+
+  // `responseEncoding` indicates encoding to use for decoding responses
+  // Note: Ignored for `responseType` of 'stream' or client-side requests
+  responseEncoding: 'utf8', // default
+
+  // `xsrfCookieName` is the name of the cookie to use as a value for xsrf token
+  xsrfCookieName: 'XSRF-TOKEN', // default
+
+  // `xsrfHeaderName` is the name of the http header that carries the xsrf token value
+  xsrfHeaderName: 'X-XSRF-TOKEN', // default
+
+  // `onUploadProgress` allows handling of progress events for uploads
+  onUploadProgress: function (progressEvent) {
+    // Do whatever you want with the native progress event
+  },
+
+  // `onDownloadProgress` allows handling of progress events for downloads
+  onDownloadProgress: function (progressEvent) {
+    // Do whatever you want with the native progress event
+  },
+
+  // `maxContentLength` defines the max size of the http response content in bytes allowed
+  maxContentLength: 2000,
+
+  // `validateStatus` defines whether to resolve or reject the promise for a given
+  // HTTP response status code. If `validateStatus` returns `true` (or is set to `null`
+  // or `undefined`), the promise will be resolved; otherwise, the promise will be
+  // rejected.
+  validateStatus: function (status) {
+    return status >= 200 && status < 300; // default
+  },
+
+  // `maxRedirects` defines the maximum number of redirects to follow in node.js.
+  // If set to 0, no redirects will be followed.
+  maxRedirects: 5, // default
+
+  // `socketPath` defines a UNIX Socket to be used in node.js.
+  // e.g. '/var/run/docker.sock' to send requests to the docker daemon.
+  // Only either `socketPath` or `proxy` can be specified.
+  // If both are specified, `socketPath` is used.
+  socketPath: null, // default
+
+  // `httpAgent` and `httpsAgent` define a custom agent to be used when performing http
+  // and https requests, respectively, in node.js. This allows options to be added like
+  // `keepAlive` that are not enabled by default.
+  httpAgent: new http.Agent({ keepAlive: true }),
+  httpsAgent: new https.Agent({ keepAlive: true }),
+
+  // 'proxy' defines the hostname and port of the proxy server.
+  // You can also define your proxy using the conventional `http_proxy` and
+  // `https_proxy` environment variables. If you are using environment variables
+  // for your proxy configuration, you can also define a `no_proxy` environment
+  // variable as a comma-separated list of domains that should not be proxied.
+  // Use `false` to disable proxies, ignoring environment variables.
+  // `auth` indicates that HTTP Basic auth should be used to connect to the proxy, and
+  // supplies credentials.
+  // This will set an `Proxy-Authorization` header, overwriting any existing
+  // `Proxy-Authorization` custom headers you have set using `headers`.
+  proxy: {
+    host: '127.0.0.1',
+    port: 9000,
+    auth: {
+      username: 'mikeymike',
+      password: 'rapunz3l'
+    }
+  },
+
+  // `cancelToken` specifies a cancel token that can be used to cancel the request
+  // (see Cancellation section below for details)
+  cancelToken: new CancelToken(function (cancel) {
+  })
+}
+```
+
+## 响应的 配置
+
+一个请求的响应包含了以下的信息。
+
+```js
+{
+  // `data` is the response that was provided by the server
+  data: {},
+
+  // `status` is the HTTP status code from the server response
+  status: 200,
+
+  // `statusText` is the HTTP status message from the server response
+  statusText: 'OK',
+
+  // `headers` the headers that the server responded with
+  // All header names are lower cased
+  headers: {},
+
+  // `config` is the config that was provided to `axios` for the request
+  config: {},
+
+  // `request` is the request that generated this response
+  // It is the last ClientRequest instance in node.js (in redirects)
+  // and an XMLHttpRequest instance in the browser
+  request: {}
+}
+```
+
+当使用`then`的时候，你会收到以下的响应:
+
+```js
+axios.get('/user/12345')
+  .then(function (response) {
+    console.log(response.data);
+    console.log(response.status);
+    console.log(response.statusText);
+    console.log(response.headers);
+    console.log(response.config);
+  });
+```
+
+
+当使用`catch`或者传递一个[rejection callback](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then)作为`then`的第二个参数，将可以在响应中使用`error`对象，这一部分在[Handling Errors](#handling-errors)中有说到。
+
+## 默认配置
+
+你指定的默认配置将会被应用到每个请求中
+
+### 全局的axios配置
+
+```js
+axios.defaults.baseURL = 'https://api.example.com';
+axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
+axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
+```
+
+### 自定义的默认实例
+
+```js
+// Set config defaults when creating the instance
+const instance = axios.create({
+  baseURL: 'https://api.example.com'
+});
+
+// Alter defaults after instance has been created
+instance.defaults.headers.common['Authorization'] = AUTH_TOKEN;
+```
+
+### 配置的优先顺序
+
+
+配置将会以以下的优先顺序被合并。默认配置在[lib/defaults.js](https://github.com/axios/axios/blob/master/lib/defaults.js#L28)里面可以找到。然后是实例的 `defaults`属性，之后就是请求的`config`参数。后者将会比前者优先权更高。下面是一个例子。
+
+```js
+// Create an instance using the config defaults provided by the library
+// At this point the timeout config value is `0` as is the default for the library
+const instance = axios.create();
+
+// Override timeout default for the library
+// Now all requests using this instance will wait 2.5 seconds before timing out
+instance.defaults.timeout = 2500;
+
+// Override timeout for this request as it's known to take a long time
+instance.get('/longRequest', {
+  timeout: 5000
+});
+```
+
+## Interceptors
+
+你可以在请求或者响应被拦截前使用 `then` 或者`catch`
+
+```js
+// Add a request interceptor
+axios.interceptors.request.use(function (config) {
+    // Do something before request is sent
+    return config;
+  }, function (error) {
+    // Do something with request error
+    return Promise.reject(error);
+  });
+
+// Add a response interceptor
+axios.interceptors.response.use(function (response) {
+    // Any status code that lie within the range of 2xx cause this function to trigger
+    // Do something with response data
+    return response;
+  }, function (error) {
+    // Any status codes that falls outside the range of 2xx cause this function to trigger
+    // Do something with response error
+    return Promise.reject(error);
+  });
+```
+
+如果你想移除一个拦截器你可以
+
+```js
+const myInterceptor = axios.interceptors.request.use(function () {/*...*/});
+axios.interceptors.request.eject(myInterceptor);
+```
+
+你可以添加一个拦截器到一个自定义的axios实例中。
+
+```js
+const instance = axios.create();
+instance.interceptors.request.use(function () {/*...*/});
+```
+
+## 处理 Errors
+
+```js
+axios.get('/user/12345')
+  .catch(function (error) {
+    if (error.response) {
+      // The request was made and the server responded with a status code
+      // that falls out of the range of 2xx
+      console.log(error.response.data);
+      console.log(error.response.status);
+      console.log(error.response.headers);
+    } else if (error.request) {
+      // The request was made but no response was received
+      // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
+      // http.ClientRequest in node.js
+      console.log(error.request);
+    } else {
+      // Something happened in setting up the request that triggered an Error
+      console.log('Error', error.message);
+    }
+    console.log(error.config);
+  });
+```
+
+使用`validateStatus`配置选项，你可以定义应该抛出错误的HTTP代码。
+
+```js
+axios.get('/user/12345', {
+  validateStatus: function (status) {
+    return status < 500; // Reject only if the status code is greater than or equal to 500
+  }
+})
+```
+
+使用`toJSON`你可以获取更多关于HTTP错误的信息
+
+```js
+axios.get('/user/12345')
+  .catch(function (error) {
+    console.log(error.toJSON());
+  });
+```
+
+## 取消
+
+你可以使用*cancel token*取消一个请求
+
+> axios的请求token API是基于 [cancelable promises proposal](https://github.com/tc39/proposal-cancelable-promises).
+
+你可以使用 `CancelToken.source` 工厂类创建一个cancel token,如下所示:
+
+```js
+const CancelToken = axios.CancelToken;
+const source = CancelToken.source();
+
+axios.get('/user/12345', {
+  cancelToken: source.token
+}).catch(function (thrown) {
+  if (axios.isCancel(thrown)) {
+    console.log('Request canceled', thrown.message);
+  } else {
+    // handle error
+  }
+});
+
+axios.post('/user/12345', {
+  name: 'new name'
+}, {
+  cancelToken: source.token
+})
+
+// cancel the request (the message parameter is optional)
+source.cancel('Operation canceled by the user.');
+```
+
+你也可以通过向`CancelToken`构造函数传递一个执行方法的方式创建一个cancel token:
+
+```js
+const CancelToken = axios.CancelToken;
+let cancel;
+
+axios.get('/user/12345', {
+  cancelToken: new CancelToken(function executor(c) {
+    // An executor function receives a cancel function as a parameter
+    cancel = c;
+  })
+});
+
+// cancel the request
+cancel();
+```
+
+> 注意: 你可以使用同样的cancel token取消几个请求
+
+## 使用 application/x-www-form-urlencoded 格式
+
+默认情况下，axios 将JavaScript对象序列成`JSON`.为了能够发送`application/x-www-form-urlencoded` 的数据格式，你可以使用以下的选项.
+
+### 浏览器
+
+在浏览器中, 你可以使用 [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) 如下的API:
+
+```js
+const params = new URLSearchParams();
+params.append('param1', 'value1');
+params.append('param2', 'value2');
+axios.post('/foo', params);
+```
+
+> 注意到 `URLSearchParams`并不支持所有的浏览器（见[caniuse.com](http://www.caniuse.com/#feat=urlsearchparams) ),但是这里有一个可供使用的 [polyfill](https://github.com/WebReflection/url-search-params) 版本（注意到要确保可以polyfill全局的变量）
+
+可选的，你可以使用 [`qs`](https://github.com/ljharb/qs) 库来编码数据：
+
+```js
+const qs = require('qs');
+axios.post('/foo', qs.stringify({ 'bar': 123 }));
+```
+
+或者使用ES6的方式
+
+```js
+import qs from 'qs';
+const data = { 'bar': 123 };
+const options = {
+  method: 'POST',
+  headers: { 'content-type': 'application/x-www-form-urlencoded' },
+  data: qs.stringify(data),
+  url,
+};
+axios(options);
+```
+
+### Node.js
+
+ 在node.js中，你可以使用[`querystring`](https://nodejs.org/api/querystring.html)以下的模块:
+
+```js
+const querystring = require('querystring');
+axios.post('http://something.com/', querystring.stringify({ foo: 'bar' }));
+```
+
+同样你也可以使用 [`qs`](https://github.com/ljharb/qs) 库.
+
+###### 注意
+
+如果你想要字符串化嵌套的对象，那么 `qs`库是我们推荐的，当然`querystring`方法同样也有一些用例上的问题 (https://github.com/nodejs/node-v0.x-archive/issues/1665)
+
+## Semver
+
+直到axios到达`1.0`发布版本，重大的改变将会被发布，同样也会有一些小的版本。例如`0.5.1`和 `0.5.4` 将会有同样的API,但是`0.6.0`将会有重大的改变。
+
+## Promises
+
+axios depends on a native ES6 Promise implementation to be [supported](http://caniuse.com/promises).
+If your environment doesn't support ES6 Promises, you can.
+
+axios取决于一个将要被实现的原生ES6 Promise的实现(http://caniuse.com/promises)，如果你的环境不支持ES6的原生Promises,你可以 [polyfill](https://github.com/jakearchibald/es6-promise).
+
+## TypeScript
+
+axios 包含了 [TypeScript](http://typescriptlang.org) 定义.
+
+```typescript
+import axios from 'axios';
+axios.get('/user?ID=12345');
+```

+## Credits
+
+axios is heavily inspired by the [$http service](https://docs.angularjs.org/api/ng/service/$http) provided in [Angular](https://angularjs.org/). Ultimately axios is an effort to provide a standalone `$http`-like service for use outside of Angular.
