在本章中，我们将了解如何通过Requests库使用POST方法，以及如何将参数传递给URL。

使用POST

对于PUT请求，Requests库具有request.post()方法，其示例如下所示-

汇入要求

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

输出

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"}

在上面显示的示例中，您可以将表单数据作为键值对传递给request.post()中的数据参数。我们还将在请求模块中看到如何使用PUT，PATCH和DELETE。

使用PUT

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

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

输出

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"}

使用PATCH

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

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

输出

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"}

使用DELETE

对于DELETE请求，Requests库具有request.delete()方法，其示例如下所示。

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

输出

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"}
