1. What are POST request parameters
In the HTTP protocol, GET and POST are two commonly used request methods.
- The GET request passes the requested data to the server through the URL parameter, while the POST request passes the data through the parameters in the request body.
- POST requests are usually used for submission of forms, uploading files, etc.
- The POST request parameter is the parameter in the request body.
In Python, we can use third-party libraries such as requests to send POST requests, and we can pass request parameters in a specific way.
2. POST request parameter delivery method in Python
There are many ways to pass POST request parameters in Python, including dictionary form, tuple form, JSON format, etc.
The following will be introduced one by one.
3. Use dictionary to pass POST request parameters
url = '/api'
data = {'name': 'John Smith', 'age': 28}
response = (url, data=data)
print()In the above code, the request parameter is saved in a dictionary and passed to the POST request as a data parameter.
As you can see, the key-value of the passed parameter corresponds to the parameters in the request body.
4. Use tuples to pass POST request parameters
import requests
url = '/api'
data = (('name', 'John Smith'), ('age', 28))
response = (url, data=data)
print()In the above code, the request parameter is saved in a tuple and passed to the POST request as a data parameter. Likewise, the tuple passing parameters corresponds to the parameters in the request body.
5. Pass POST request parameters using JSON format
import requests
import json
url = '/api'
data = {'name': 'John Smith', 'age': 28}
headers = {'Content-type': 'application/json'}
response = (url, data=(data), headers=headers)
print()In the above code, the request parameter is saved in a dictionary and converted to a string in JSON format using the method. The format of the request body is specified as JSON through the headers parameter.
In this way, the parameters are not passed in the form of a key-value, but appear in the request body as a JSON format string.
6. Use files to pass POST request parameters
import requests
url = '/api'
files = {'file': open('', 'rb')}
response = (url, files=files)
print(In the above code, the file data is read using the open method and saved as a file object in binary form.
Pass the file object as a parameter to the POST request to implement the file upload operation.
7. Conclusion
Through the above methods, we can flexibly pass POST request parameters in Python, and can easily perform form submission, file upload and other operations.
The above is personal experience. I hope you can give you a reference and I hope you can support me more.
