Python HTTP request: a powerful tool for easily mastering network communication

python HttpThe request library is a powerful tool for sending HTTP requests. It provides a set of simple The easy-to-use api enables you to easily communicate with the WEBserver. The HTTP request library has the following characteristics:

• Easy to use: The HTTP request library provides a set of simple and easy-to-use APIs that enable you to send HTTP requests easily.
• Powerful functions: The HTTP request library supports multiple HTTP request methods, including GET, POST, PUT, DELETE, etc., and also supports multiple HTTP headers and formats.
• Flexible configuration: The HTTP request library allows you to flexibly configure request parameters, such as timeout, number of retries, etc.
• Support multiple protocols: The HTTP request library supports multiple protocols, including HTTP, https, SOCKS, etc.

Send HTTP request

Sending an HTTP request is very simple. You only need to create an HTTP request object and then use the object to send the request. The following is a demo code:

import requests

# 创建一个HTTP请求对象
url = "http://www.example.com"
response = requests.get(url)

# 检查响应状态码
if response.status_code == 200:
# 请求成功，处理响应内容
print(response.text)
else:
# 请求失败，处理错误
print("请求失败，状态码：", response.status_code)

Get request response

After sending the HTTP request, you can get the request response. You can get the response using the text property of the HTTP request object, or you can get the js<strong class="keylink">ON data of the response using the </strong>JSON() method. The following is a demo code:

# 获取响应
response = requests.get("http://www.example.com")
print(response.text)

# 获取响应的JSON数据
response = requests.get("http://www.example.com/api/v1/users")
data = response.json()
print(data)

Send POST request

POST request is used to send data to the server. The following is a demo code:

# 发送POST请求
data = {"username": "admin", "passWord": "password"}
response = requests.post("http://www.example.com/login", data=data)

# 检查响应状态码
if response.status_code == 200:
# 登录成功，处理响应内容
print(response.text)
else:
# 登录失败，处理错误
print("登录失败，状态码：", response.status_code)

Send PUT request

PUT request is used to update data on the server. The following is a demo code:

# 发送PUT请求
data = {"username": "admin", "password": "new_password"}
response = requests.put("http://www.example.com/users/1", data=data)

# 检查响应状态码
if response.status_code == 200:
# 更新成功，处理响应内容
print(response.text)
else:
# 更新失败，处理错误
print("更新失败，状态码：", response.status_code)

Send DELETE request

DELETE request is used to delete data on the server. The following is a demo code:

# 发送DELETE请求
response = requests.delete("http://www.example.com/users/1")

# 检查响应状态码
if response.status_code == 200:
# 删除成功，处理响应内容
print(response.text)
else:
# 删除失败，处理错误
print("删除失败，状态码：", response.status_code)
