`requests`是一个非常流行的Python库,用于处理HTTP请求。它使得在Python程序中发送HTTP/1.1请求变得更加简单和直观。requests库提供了一组简单易用的接口,支持GET、POST、PUT、DELETE等常见的HTTP方法,以及更复杂的请求功能,如文件上传、cookies管理、会话保持等。
以下是使用`requests`库的一些基本操作:
1. **发送GET请求**:
```python
import requests
response = requests.get('http://www.example.com')
```
2. **发送POST请求**:
```python
data = {'key': 'value'}
response = requests.post('http://post-api.example.com', data=data)
```
3. **处理响应**:
```python
if response.status_code == 200:
content = response.text
# 或者使用json()方法处理JSON响应
json_content = response.json()
```

requests python 转码
Requests库是Python中一个常用的HTTP库,它可以方便地发送HTTP请求和处理HTTP响应。在使用Requests库时,如果需要对请求或响应中的内容进行编码或解码,可以使用Python内置的编码库或第三方库进行转码。例如,可以使用Python内置的base64库对二进制数据进行编码和解码,也可以使用第三方库chardet对文本进行自动检测编码并进行转码。此外,Requests库本身也提供了一些编码和解码的方法,例如在发送POST请求时,可以使用multipart/form-data编码方式对请求体进行编码,具体使用方法可以参考Requests官方文档中的相关章节。
python requests python 400
A 400 error in Python requests means that the request made to the server was invalid or malformed. This can happen for a variety of reasons, such as missing or incorrect parameters in the request, an unsupported request method or HTTP version, or invalid authentication credentials.
To resolve this error, you should review the request parameters and ensure that they are correct and complete. You may also need to check the server logs or documentation to determine the specific cause of the error.
Here is an example of handling a 400 error in Python requests:
```
import requests
url = 'https://example.com/api/endpoint'
params = {'param1': 'value1', 'param2': 'value2'}
response = requests.get(url, params=params)
if response.status_code == 400:
print('Error: Bad request')
print(response.text)
else:
print(response.json())
```
In this example, we are making a GET request to an API endpoint with some parameters. If the response status code is 400, we print an error message and the response text. Otherwise, we assume that the response is valid JSON and print its contents.
