RobotFramework自动化框架RequestsLibrary之Post Request

RF环境安装引用了https://blog.csdn.net/qq_15158911/article/details/80592526，所以也跟着统一了一下环境（其实现在python3各种库也都兼容了，所以也可以用python3，但各安装包都安装与之对应的版本）

1、首先根据提供的别名查找会话并在会话中发送POST请求

alias, uri, data={}, headers=None, files={}, allow_redirects=None（其中alias为接口别名，uri为url后半段：注：可以为空（有些Url地址直接为http://ip:port的形式），data为接口传递的参数，headers为接口请求头信息）

2、接口导入的库：requestsLibrary，Collections（可以通过python自带工具pip install +库名安装），新建robot套件，然后点击右侧“库”，在弹出窗口添加如下两个库名

3、右击套件新建testcase，点击打开后在新建case的Eidit界面做接口的参数化设置（此处涉及data两种方式，一种是直接将post上传的json直接设置好用例需要设置的值，另一种是将json内各参数直接拎出来做参数化如下图）

直接将data值参数化：

 

将传递的method和params下的各个参数都做参数化（此好处就是在做条件组合时每个参数可以单独设置）：

 

4、说明：

（1）headers请求头信息参数${headers}，各个请求可能请求头不一样，按实际情况设置（创建字典）；

（2）创建session时，设置session别名（alias），请求的Url，以及headers参数（创建session）；

（3）设置data参数${data}（创建字典）；

（4）设置post请求方式以及请求参数：Post request（session别名）、uri、data=${data}、headers=${headers}（请求方式及请求参数设置）

（5）打印上传的参数和值（Log：日志打印）；

（6）设置断言（Should Be equal As Strings）；断言的作用不懂得可以问百度0.0.

（7）执行完成后，删除所有session（Delete All Sessions）；

5、源码地址：https://github.com/Duanxh2018/automated_testing.git

6、执行结果（两者打印执行结果日志如下：可分别通过GetAccount.test_GetAccount、GetAccount.test_getAccountData下面日志查看执行结果）：

由于刚开始学习，对于日志显示的type问题现在还没找到解决方法，如果有哪位老鸟路过，还请告知下！
