使用Postman发送POST请求时提示page参数缺失，请求报错求助

Hey there! Let's break down why you're hitting that "Invalid web service call, missing value for parameter: 'page'." error when sending your POST request in Postman. Here are the key areas to check:

• Double-check where the page parameter should live
  Some APIs expect page in the URL query string (like https://your-api.com/endpoint?page=1), while others require it in the POST request body.

  • If it's a query parameter: Head to the Params tab in Postman, add a key named page, and set its value (e.g., 1).
  • If it's in the request body:
    • For form-data/x-www-form-urlencoded formats: Go to the Body tab, select the right format, and add the page field with your value.
    • For JSON bodies: Make sure your request body includes the page key, like this:

      {
        "page": 1,
        "yourOtherParam": "yourValue"
      }
      

      Also, confirm the Content-Type header is set to application/json (you can add this in the Headers tab).

• Verify the parameter name is exact
  APIs are often case-sensitive! Ensure you're using page (all lowercase) and not Page, PAGE, or a misspelled version like pgae. Even a tiny typo will cause the server to miss the parameter.

• Make sure the parameter has a valid value
  Don't leave page empty or set it to a non-valid value (like a string when the API expects a number). Double-check that the value you're sending is something the server accepts (e.g., 1, 2, etc.).

• Check your request headers
  A mismatched Content-Type header can prevent the server from parsing your request body correctly. For example, if you're sending JSON but have Content-Type set to application/x-www-form-urlencoded, the server won't recognize the page parameter in your JSON body.
