思路图
一、配置HTTP
1）接口类型：
接口一般来说有两种，一种是程序内部的接口，一种是系统对外的接口。
(1) webservice接口：走soap协议通过http传输，请求报文和返回报文都是xml格式的，我们在测试的时候都要通过工具才能进行调用，测试。
(2) http api 接口：走http协议，通过路径来区分调用的方法，请求报文都是key-value形式的，返回报文一般都是json串，有get和post等方法。
2）接口的请求方法：get（）和post（）
常用的几种接口请求方式：
(1) GET：从指定资源获取数据
(2) POST：向指定的资源请求被处理的数据（例如用户登录）
(3) PUT：上传指定的URL，一般是修改，可以理解为数据库中的 update
(4) DELETE：删除指定资源
3）get（）方法对应的参数：url, headers, params, timeout
对于requests提供的get方法，有几个常用的参数：
url：显而易见，就是接口的地址url啦
headers：定制请求头（headers），例如：content-type = application/x-www-form-urlencoded
params：用于传递测试接口所要用的参数，这里我们用python中的字典形式（key：value）进行参数的传递。
timeout：设置接口连接的最大时间（超过该时间会抛出超时错误）
4）post（）方法对应的参数：url, headers, data, files, timeout
其中，传参的类型content-type有哪几种？
