根因分析

API 端点需要特定的查询参数，但请求 URL 中未包含该参数。

English

The API endpoint requires a specific query parameter that was not included in the request URL.

解决方案

  1. Add the missing query parameter to the URL. For example, change /api/items to /api/items?limit=10. In JavaScript: fetch('/api/items?limit=' + limit). In Python requests: requests.get('/api/items', params={'limit': 10})
  2. Check the API documentation for all required parameters. Use a tool like Postman or curl to test the endpoint: curl -X GET 'https://api.example.com/items?limit=10'
  3. If using an SDK, verify that the function call includes all required arguments. In some SDKs, the parameter may be optional with a default; check the method signature.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The server parses query parameters from the URL, not headers.

  2. 95% 失败

    GET requests typically do not have a body; the server expects the parameter in the URL.

  3. 85% 失败

    Parameter names are case-sensitive and must match exactly.
