Python processes JSON data returned by request

One . Use Python Of requests Library request —— Response result processing

In practice , The response of many interfaces is json Formatted data , It needs to be processed and analyzed . involves json There are two methods of data processing ： Serialization and deserialization ：

python in serialize —— take python The dictionary of is converted into json Format string , For storage or transmission ;

Deserialization —— take json Format string to python Dictionaries , It is used for analyzing and processing .

JSON and DICT Format conversion method ：

import json
# Serialized into json character string
d = {‘name'：‘jod'}
j = json.dumps(d)
# Deserialize into a dictionary
print json.loads(j)

And in the requests In the library , no need json.loads Method to deserialize , It provides Of the response object json Method , Used to correct json Deserialize the response body of ：

r = requests.get(url)

r.json()

Two . request The returned data can be processed in two ways ：

    1. Yes request The response object returned from the initiation request is .json() operation ,.json The operation returns a dictionary type （ If the returned result is empty, an error will be reported ）, as follows ：

    2. Yes request In the response object of the request text Data processing json.loads(text) operation , The dictionary type is returned after the operation （ This method is recommended , Judge before use text Is it empty , An error will also be reported if it is empty ）, as follows ：

3、 ... and .  Use request Send the request and process the returned result -- Basic template

import requests
import json
# With get Method to request , You can attach parameters directly to the back , You can also pass in parameters to
response=requests.get(f"http://XXXXX/anyq?question={question}")
param={"question":question}
res = requests.get(url='https://b.faloo.com/l/0/1.html',params=param)
# The formal parameter here is params
# If it is post, We can use data Form as a parameter
params = {"username": self.username,"email": self.email, "password": self.password}
response = requests.post(request_url, data=params)
# The formal parameter here is data
# If the data returned is unicode code , for example
