我封装了一下，为什么请求了两次

[jackluo2012]

`const flyio = require("flyio");
//添加请求拦截器
flyio.interceptors.request.use((request) => {
request.baseURL = baseURL;
//给所有请求添加自定义header
request.headers["X-Tag"] = "flyio";
request.url = request.url + "?beid=3";

//打印出请求体
console.log(request.body);
//终止请求
return request;
});
//添加响应拦截器，响应拦截器会在then/catch处理之前执行
flyio.interceptors.response.use( (response) => {
Toast(response.data.status)
if(response.data.status == 1){
return response.data.result
}
}, (err) => {
console.log(err);
//发生网络错误后会走到这里
//return Promise.resolve("ssss")
}
)

// get
export const _get = (req) => {
return flyio.get(req.url,req.data)
}

// post
export const _post = (req) => {
return flyio.post(req.url, req.data)
}
`

你的请求是不是夸域的？对于非简单的跨域请求，浏览器都会先发起一次预检请求(options)
