Python Requests put() 方法

Python Requests 的`put()`方法用于向指定的URL发送PUT请求。此方法用于使用提供的数据更新或替换给定URL处的资源。

`put()`方法类似于`requests.post()`，但专门用于替换现有资源，而不是创建新资源。它接受URL、数据、报头、文件、身份验证、超时等参数来定制请求。

此方法返回一个响应对象，其中包含有关请求状态、报头和内容的信息，可以根据应用程序的需求进一步处理。

语法

以下是Python Requests `put()`方法的语法和参数：

requests.get(url, params=None, **kwargs)

参数

以下是Python Requests `put()`方法的参数：

• url: url是要发送PUT请求的资源的URL。
• data(可选): 这是要与PUT请求一起发送的数据。
• json(可选): 要在主体中发送的JSON数据。
• kwargs(可选): 可以传递的可选参数，包括headers、cookies、auth、timeout等。

返回值

此方法返回一个Response对象。

示例1

以下是使用python requests `put()`方法的基本PUT请求的基本示例：

import requests

# Define the URL
url = 'https://httpbin.org/put'

# Define the data to be sent in the request body
data = {'key1': 'value1', 'key2': 'value2'}

# Send the PUT request with the data
response = requests.put(url, json=data)

# Print the response status code
print('Status Code:', response.status_code)

# Print the response content
print('Response Content:', response.text) 

输出

Status Code: 200
Response Content: {
  "args": {},
----------------
----------------
----------------
},
  "origin": "110.226.149.205",
  "url": "https://httpbin.org/put"
}

示例2

当使用Python中的requests模块发送PUT请求时，我们可以处理请求过程中可能发生的错误。以下示例处理put请求中的错误：

import requests

try:
    response = requests.put('https://api.example.com/nonexistent', timeout=5)
    response.raise_for_status()  # Raises an HTTPError if the status code is 4xx, 5xx
except requests.exceptions.HTTPError as err:
    print(f'HTTP error occurred: {err}')
except requests.exceptions.RequestException as err:
    print(f'Request error occurred: {err}') 

输出

Request error occurred: HTTPSConnectionPool(host='api.example.com', port=443): Max retries exceeded with url: /nonexistent (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x000001BC03605890>: Failed to resolve 'api.example.com' ([Errno 11001] getaddrinfo failed)"))

示例3

这是一个使用python requests `put()`方法设置超时的PUT请求示例：

import requests

# Define the URL
url = 'https://httpbin.org/put'

# Define the data to be sent in the request body
data = {'key1': 'value1', 'key2': 'value2'}

# Set the timeout for the request (in seconds)
timeout = 5

try:
    # Send the PUT request with the data and timeout
    response = requests.put(url, json=data, timeout=timeout)

    # Print the response status code
    print('Status Code:', response.status_code)

    # Print the response content
    print('Response Content:', response.text)

except requests.Timeout:
    # Handle timeout error
    print('Timeout Error: Request timed out.')

except requests.RequestException as e:
    # Handle other request exceptions
    print('Request Exception:', e)

输出

Status Code: 200
Response Content: {
  "args": {},
-------------------
-------------------
-------------------
 },
  "origin": "110.226.149.205",
  "url": "https://httpbin.org/put"
}
