Requests - 处理 GET 请求

本章将重点介绍 GET 请求，这是最常见且最常用的请求。请求模块中 GET 的操作非常简单。这是一个使用 GET 方法处理 URL 的简单示例。

示例

import requests
getdata = requests.get('https://jsonplaceholder.typicode.com/users')
print(getdata.content)
getdata.content, will print all the data available in the response.   

输出

E:\prequests>python makeRequest.py
b'[
 {
 "id": 1,
 "name": "Leanne Graham",
 "username": "Bret",

"email": "Sincere@april.biz",

 }
 }

您还可以使用 param 属性将参数传递给 get 方法，如下所示 −

import requests
payload = {'id': 9, 'username': 'Delphine'}
getdata = requests.get('https://jsonplaceholder.typicode.com/users',
params=payload)
print(getdata.content)

详细信息存储在对象有效负载中的键/值对中，并传递给 get() 方法内的 params。

输出
