Introduction:

requests is an http client library for Python, similar to urlib and urlib2. The requests module is developed based on the urlib module, and the code implementation is simpler.

Module installation:

pip install requests, just import requests directly when using the requests module.

Simple use of requests:

http protocol interface, the request method is divided into get and post, these two are the most commonly used. Commonly used forms of request parameters include key-value, json, file upload, interface addition of cookies, headers and other operations.

get request-url splicing parameters: 

<span style="color: #0000ff">import</span><span style="color: #000000"> requests
url </span>= <span style="color: #800000">'</span><span style="color: #800000">http://127.0.0.1:5000/gettest?username=abc</span><span style="color: #800000">'</span>
<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字符串：{"msg": "pass"}</span>
res =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url).text</span><span style="color: #0000ff"><br></span>

You can also use .json(), the return result type is a dictionary (Note: The return value type of the interface request is related to the return definition type of the interface)

<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字典：{'msg': 'pass'}</span>
res_dic =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url).json()</span><span style="color: #0000ff"><br></span>

get request - the request parameter type is in key-value form: 

<span style="color: #0000ff">import</span><span style="color: #000000"> requests

</span><span style="color: #008000">#</span><span style="color: #008000">返回结果类型是str：{"msg": "pass"}</span>
res = requests.<span style="color: #ff0000">get</span>(url, data).text

You can also use .json(), the return result type is a dictionary (Note: The return value type of the interface request is related to the return definition type of the interface)

<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字典:{"msg": "pass"}</span>
res_dic =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url, data).json()</span><span style="color: #0000ff"><br></span>
