根因分析
API 端点要求在 JSON 请求体中包含特定字段,但该字段被省略或设置为 null。
English
The API endpoint requires a specific field in the JSON request body, but it was omitted or set to null.

-
查阅 API 文档确认必填字段。将缺失的字段添加到请求体中。示例:curl -X POST https://api.example.com/users -H 'Content-Type: application/json' -d '{"email": "[email protected]", "name": "John"}' -
在发送前使用 JSON schema 验证器(如 ajv)在本地验证请求体。
无效尝试
常见但无效的做法:
-
20% 失败
Changing the HTTP method from POST to PUT does not fix the missing field issue; the server still validates the request body.
-
50% 失败
Adding the field with an empty string instead of a valid value may cause a different validation error (e.g., 'email' must be a valid email).
