usecurlWhen calling an interface with parameters, the method of passing parameters depends on the HTTP method and interface requirements. Here are examples of different scenarios:
1. GET request (parameters are in URL query string)
curl "/api?name=John&age=30"
Notice: If the parameter contains special characters (such as spaces), it is required-GCooperate--data-urlencodeAutomatic encoding:
curl -G /api \ --data-urlencode "query=hello world" \ --data-urlencode "page=1"
The generated URL:/api?query=hello%20world&page=1
2. POST request (form data format)
curl -X POST \ -d "name=John" \ -d "age=30" \ /api
Or merge parameters:
curl -X POST -d "name=John&age=30" /api
Default header：Content-Type: application/x-www-form-urlencoded
3. POST request (JSON format)
curl -X POST \
-H "Content-Type: application/json" \
-d '{"name":"John", "age":30}' \
/api
4. Mix URL parameters and request body (POST)
curl -X POST \ "/api?category=tech" \ -d "title=Hello&content=World"
5. Upload file (Multipart form)
curl -X POST \ -F "file=@/path/to/" \ -F "description=My File" \ /upload
6. PUT/PATCH request
curl -X PUT \
-H "Content-Type: application/json" \
-d '{"id": 1, "status": "active"}' \
/api/resource/1
