解决方案

  1. 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"}'
  2. 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:

  1. 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.

  2. 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).
