Katalon Studio中响应体内容解析失败问题求助

Hey there, let's work through why your JsonSlurper code is failing on this particular response even though it works for others. Here are actionable steps to diagnose and fix the issue:

• Validate the raw response content
  First, confirm the response is actually valid JSON. APIs sometimes return unexpected content (like HTML error pages, extra whitespace, or malformed JSON) when something goes wrong. Print the raw content to spot anomalies:

  String getContent = get_response.getResponseBodyContent()
  println "Raw Response: " + getContent // Check this output for issues like unclosed quotes or non-JSON text
  

• Fix encoding mismatches
  JsonSlurper depends on correct string encoding. If the response uses an encoding other than your default (e.g., GBK instead of UTF-8), converting it incorrectly can break parsing. Try explicitly specifying the encoding:

  // Option 1: Fetch content with explicit encoding
  String getContent = get_response.getResponseBodyContent("UTF-8")
  
  // Option 2: Convert bytes directly with correct encoding
  String getContent = new String(get_response.getResponseBodyAsBytes(), "UTF-8")
  

• Handle non-JSON responses gracefully
  APIs often return non-JSON content for error states (like 404/500 errors with HTML bodies). Add a check for the Content-Type header before parsing:

  String getContent = get_response.getResponseBodyContent()
  JsonSlurper slurper = new JsonSlurper()
  
  if (get_response.getContentType()?.contains("application/json")) {
      Map parsedJson = slurper.parseText(getContent)
  } else {
      println "Skipping non-JSON response: Content-Type is ${get_response.getContentType()}"
      println "Response content: ${getContent}"
  }
  

• Parse bytes instead of strings
  Bypassing string conversion can avoid encoding-related issues entirely. Use JsonSlurper's method that parses raw bytes:

  Map parsedJson = slurper.parse(get_response.getResponseBodyAsBytes())
  

• Clean up problematic characters
  Sometimes responses contain unescaped control characters (like invisible non-printable chars) that break parsing. Try sanitizing the content first:

  getContent = getContent.replaceAll("[\\p{Cntrl}&&[^\r\n\t]]", "") // Remove non-printable control characters
  Map parsedJson = slurper.parseText(getContent)
  

If you can share the specific error message (e.g., the stack trace from the failure) or redacted raw response content, we can narrow this down even further!
