使用步骤

运行前的准备：

安装virtualenv 虚拟环境

ubuntu: apt-get install virtualenv windows: pip install virtualenv
激活虚拟环境

virtualenv venv venv\Script\activate
安装Flask

pip install Flask
导入Flask必需的插件

pip install -r requirements.txt
安装测试RESTful API工具

pip install httpie

配置

（示例代码中已经包含了data-dev.sqlite数据库文件）初始化数据库迁移脚本

python manage.py db init

创建数据库，类似于db.create_all()，以后每一次更新数据模型后，都要运行

python manage.py db migrate -m "init migration"

把更新后的数据模型应用到数据库

python manage.py db upgrade

运行网站

python manage.py runserver

RESTful API测试

发起GET请求

http --json GET http://localhost:5000/api/v1.0/posts/

或

http --json --auth : GET  http://localhost:5000/api/v1.0/posts/

返回

{
    "author": "http://localhost:5000/api/v1.0/users/1",
    "body": "hello world",
    "timestamp": "Sun, 22 Dec2015 09:23:56 GMT",
    "url": "http://localhost:5000/api/v1.0/posts/23"
}

发起POST请求

http --json --auth <email>:<password> GET  http://localhost:5000/api/v1.0/posts/

获取认证令牌

http --json --auth <email>:<password> GET  http://localhost:5000/api/v1.0/token

返回

{
    "expiration":36000,
    "token": "exkfjsljdfis..."
}

使用认证令牌

http --json --auth exkfjsljdfis...: GET http://localhost:5000/api/v1.0/posts/

返回：

{
    "next_page": "http://localhost:5000/api/v1.0/posts/?page=2",
    "prev_page": null,
    "page_count": 20,
    "total_count": 109
    "posts": [
        {
            "author": "http://localhost:5000/api/v1.0/users/1",
            "body": "Hi, this is my first tweet.",
            "body_html": null,
            "timestamp": "Mon, 09 May 2016 13:48:52 GMT",
            "url": "http://localhost:5000/api/v1.0/posts/1"
        },
        {
            "author": "http://localhost:5000/api/v1.0/users/1",
            "body": "this is my second tweet",
            "body_html": null,
            "timestamp": "Mon, 09 May 2016 13:49:12 GMT",
            "url": "http://localhost:5000/api/v1.0/posts/2"
        },
        ....
    ]
}

测试

代码覆盖率

详细用法，见manage.py文件

pip install coverage

自动化测试

Flask内建的测试客户端编写单元测试框架

test_client

Selenium进行端到端测试

pip install selenium
