Requests - 处理 GET 请求

本章将集中介绍 GET 请求，该请求最为常用，并且经常使用。requests 模块中 GET 的工作方式非常简单。以下是一个使用 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'[\n {\n "id": 1,\n "name": "Leanne Graham",\n "username": "Bret",\n
"email": "[email protected]",\n "address": {\n "street": "Kulas Light
",\n "suite": "Apt. 556",\n "city": "Gwenborough",\n "zipcode": "
92998-3874",\n "geo": {\n "lat": "-37.3159",\n "lng": "81.149
6"\n }\n },\n "phone": "1-770-736-8031 x56442",\n "website": 
"hildegard.org",\n "company": {\n "name": "Romaguera-Crona",\n "catchPhrase": 
"Multi-layered client-server neural-net",\n "bs":
"harness real-time e-markets"\n }\n }

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)

详细信息存储在键/值对中的对象 payload 中，并传递给 get() 方法内的 params。

输出

E:\prequests>python makeRequest.py
b'[\n {\n "id": 9,\n "name": "Glenna Reichert",\n "username": "Delphine",
\n "email": "[email protected]",\n "address": {\n "street":
"Dayna Park",\n "suite": "Suite 449",\n "city": "Bartholomebury",\n
"zipcode": "76495-3109",\n "geo": {\n "lat": "24.6463",\n
"lng": "-168.8889"\n }\n },\n "phone": "(775)976-6794 x41206",\n "
website": "conrad.com",\n "company": {\n "name": "Yost and Sons",\n
"catchPhrase": "Switchable contextually-based project",\n "bs": "aggregate
