Requests 简明教程

Requests - Handling GET Requests

本章将更集中于 GET 请求，GET 请求是最常见且最常用的。请求模块中的 GET 工作非常简单。下面是一个使用 URL 和 GET 方法工作的简单示例。

This chapter will concentrate more on the GET requests, which is the most common and used very often. The working of GET in the requests module is very easy. Here is a simple example about working with the URL using the GET method.

Example

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

Output

E:\prequests>python makeRequest.py
b'[\n {\n "id": 1,\n "name": "Leanne Graham",\n "username": "Bret",\n
"email": "Sincere@april.biz",\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 }

您还可以使用 param 属性将参数传递给 get 方法，如下所示 −

You can also pass parameters to the get method using the param attribute as shown below −

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

这些详细信息存储在键/值对中的对象有效负载中，并传递到 get() 方法内部的 params。

The details are stored in the object payload in the key/value pair and passed to params, inside get() method.

Output

E:\prequests>python makeRequest.py
b'[\n {\n "id": 9,\n "name": "Glenna Reichert",\n "username": "Delphine",
\n "email": "Chaim_McDermott@dana.io",\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
