The Requests module gets the response content
The response includes the response line, response header, and response body content, and the returned response information can be obtained through the Requests module. The obtained response content is also the actual result obtained by the execution of the interface test.
get response line
get response header
Get other response information
Code example:
# Import requests module
import requests
r = requests.get("https://www.baidu.com")
print(r.status_code) #Response status code
print(r.reason) #Response information
print(r.headers) # Get the response header to return the dict type, you can continue to use get to get the specified value
# Get other response information:
print(r.url) #Get the request address
print(r.cookies) #Get cookies
print(r.encoding) #Get The encoding format of the response
response body
According to the situation of different response body content, the Requests module has four different processing methods
1. Ordinary text data
Requests automatically decodes content from the server. Most unicode character sets can be decoded seamlessly. After a request is made, Requests makes an educated guess about the encoding of the response based on the HTTP headers. Requests will use its guessed text encoding when you access response.text. response.text has a high probability of garbled characters after use, you can first use the response.encoding attribute to change the encoding, as shown below:
Code example:
# 1, normal text data
url = "http://www.hnxmxit.com/"
response = requests.get(url=url)
print(response.content.decode("utf-8"))

2. Binary data
For non-text requests, response.content can access the request response body in bytes. And the Requests module will automatically decode the response data of gzip and deflate transfer encoding for you
# 2, binary data
response =requests.get("https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=2073439784,2147418910&fm=26&gp=0.jpg")
print(type(response.content)) # output Binary image data type
with open("E:/baidu.gif","wb") as f: # Write binary data to local file
f.write(response.content)

Three, json data
There is a built-in JSON decoder response.json() in Requests to process the returned JSON data. After use, the returned data will be treated as a json data object in python. response.json() will throw an exception if JSON decoding fails.
url = 'https://api.weixin.qq.com/cgi-bin/token'
data = {'Grant_type': 'Client_credential',
'Appid': 'WXF14419077856' ',
' Sec RET ': 92A113BD4B5FFDC72144740dc7123C99'}
Response = requests.get(url=url,params=data)
# The response is str type, so we need to convert the response into json
json_obj = response.json()
token = json_obj['access_token']
print(token)
4. Original response content (generally not used)
If you need to get the raw socket response from the server, you can use response.raw. If you are sure to get it, you also need to set stream=True in the initial request.
# 4, Raw response content (generally not used) url = "https://www.baidu.com" response = requests.get(url=url,stream=True) print(response.raw.read(10))
Practical case
Optical theory is useless, you have to learn to follow along, and you have to do it yourself, so that you can apply what you have learned to practice. At this time, you can learn from some actual combat cases.
