如何使用karate.read与karate.write保留文件编码？ISO-8859-1编码XML文件读取乱码问题求助

The garbled output you're seeing happens because Karate is likely reading your ISO-8859-1 encoded XML file using the JVM's default encoding (often UTF-8) instead of the specified ISO-8859-1. Even setting -Dfile.encoding in Maven might not always override this reliably in all contexts. Here's how to fix it:

Step 1: Explicitly Specify Encoding When Reading the File #

Karate's read() function accepts an optional second parameter to specify the file encoding. Update your test script to explicitly use ISO-8859-1 when reading the XML:

* def xmlData = karate.read("someFile.xml", "ISO-8859-1")
* karate.log(karate.prettyXml(xmlData))

This ensures the file's bytes are decoded correctly into a Java string using the proper encoding, preserving special characters like å.

Additional Checks to Ensure Success #

• Confirm File Encoding: Double-check that someFile.xml is actually saved as ISO-8859-1. Some text editors (like VS Code) may default to UTF-8 unless you explicitly set the encoding when saving.
• Upgrade Maven Surefire Plugin: Your current plugin version (2.10) is quite outdated. Newer versions handle JVM arguments more reliably. Consider upgrading to the latest stable version (e.g., 3.2.5):

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.2.5</version>
    <configuration>
      <argLine>-Dfile.encoding=ISO-8859-1</argLine>
    </configuration>
  </plugin>
  

• Console Encoding: Ensure the console where you run your tests supports displaying ISO-8859-1 characters. If you're using a terminal that defaults to UTF-8, you might still see odd characters, but the underlying string in Karate will be correct (you can verify this by writing the output to a file instead of logging to the console).

When you run the modified test, the output should correctly display:

<text>å bestå gjennom fem århundrer også tålt</text>
