Requests 简明教程

Handling POST, PUT, PATCH and DELETE Requests

在本章中，我们将介绍如何使用请求库来使用 POST 方法以及如何将参数传递到 URL 中。

In this chapter, we will understand how to use the POST method using requests library and also pass parameters to the URL.

Using POST

对于 PUT 请求，Requests 库有 requests.post() 方法，示例如下 −

For PUT request, the Requests library has requests.post() method, the example of it is shown below −

import requests

myurl = 'https://postman-echo.com/post'
myparams = {'name': 'ABC', 'email':'xyz@gmail.com'}
res = requests.post(myurl, data=myparams)
print(res.text)

Output

E:\prequests>python makeRequest.py
{"args":{},"data":"","files":{},"form":{"name":"ABC","email":"xyz@gmail.com"},
"headers":{"x-forwarded-proto":"https","host":"postman-echo.com","content-
length":"30","accept":"*/*","accept-encoding":"gzip,deflate","content-
type":"application/x-www-form-urlencoded","user-agent":"python-
requests/2.22.0","x-forwarded-
port":"443"},"json":{"name":"ABC","email":"xyz@gmail.com"},
"url":"https://postman-echo.com/post"}

在前述示例中，你可以将表单数据作为键值对传递到 requests.post() 内部的 data 参数。我们还将了解如何在请求模块中使用 PUT、PATCH 和 DELETE。

In the example shown above, you can pass the form data as key-value pair to the data param inside requests.post(). We will also see how to work with PUT, PATCH and DELETE in requests module.

Using PUT

对于 PUT 请求，Requests 库具有 requests.put() 方法，其示例如下所示。

For PUT request, the Requests library has requests.put() method, the example of it is shown below.

import requests
myurl = 'https://postman-echo.com/put'
myparams = {'name': 'ABC', 'email':'xyz@gmail.com'}
res = requests.put(myurl, data=myparams)
print(res.text)

Output

E:\prequests>python makeRequest.py
{"args":{},"data":"","files":{},"form":{"name":"ABC","email":"xyz@gmail.com"},
"headers":{"x-forwarded-proto":"https","host":"postman-echo.com","content-
length":
"30","accept":"*/*","accept-encoding":"gzip, deflate","content-
type":"applicatio
n/x-www-form-urlencoded","user-agent":"python-requests/2.22.0","x-forwarded-
port
":"443"},"json":{"name":"ABC","email":"xyz@gmail.com"},
"url":"https://postman-echo.com/put"}

Using PATCH

对于 PATCH 请求，Requests 库具有 requests.patch() 方法，其示例如下所示。

For the PATCH request, the Requests library has requests.patch() method, the example of it is shown below.

import requests
myurl = https://postman-echo.com/patch'
res = requests.patch(myurl, data="testing patch")
print(res.text)

Output

E:\prequests>python makeRequest.py
{"args":{},"data":{},"files":{},"form":{},"headers":{"x-forwarded-
proto":"https"
,"host":"postman-echo.com","content-length":"13","accept":"*/*","accept-
encoding
":"gzip, deflate","user-agent":"python-requests/2.22.0","x-forwarded-
port":"443"
},"json":null,"url":"https://postman-echo.com/patch"}

Using DELETE

DELETE 请求中，Requests 库有 requests.delete() 方法，以下所示为示例。

For the DELETE request, the Requests library has requests.delete() method, the example of it is shown below.

import requests
myurl = 'https://postman-echo.com/delete'
res = requests.delete(myurl, data="testing delete")
print(res.text)

Output

E:\prequests>python makeRequest.py
{"args":{},"data":{},"files":{},"form":{},"headers":{"x-forwarded-
proto":"https"
,"host":"postman-echo.com","content-length":"14","accept":"*/*","accept-
encoding
":"gzip, deflate","user-agent":"python-requests/2.22.0","x-forwarded-
port":"443"
},"json":null,"url":"https://postman-echo.com/delete"}
