如何在空手道中使用 FileUtils？

Question

需要将编码后的字符串转换生成PDF并保存为pdf进行比较。

示例功能文件：

Feature: Compute All  

Scenario: trial and error
* call read('common.feature')
* def xyz = getMDash( 'my password')
* print xyz
* call read('classpath:/test/java/com/intuit/karate/FileUtils.java')



* def doWork =
"""
function('temp.txt','hello world') {
  var JavaDemo = Java.type('com.intuit.karate.FileUtils');
  var jd = new JavaDemo();
  jd.writeToFile('temp.txt','hello world');  
}
"""

* def result = call writeToFile 'temp.txt','hello world'


* def FileUtils = Java.type('com.intuit.karate.FileUtils')
* def result = FileUtils.writeToFile('temp.txt','hello world')

使用给定的示例。

日志错误：

需要有关在空手道中使用 fileUtils 的帮助。

Answer 1

空手道不支持写入文件，因为这是不好的做法。我不知道您在上面要做什么。通常您通过将响应保存在内存中来进行比较，请参阅文件上传示例：https://github.com/intuit/karate/blob/master/karate-demo/src/test/java/demo/upload/upload.feature

同样的例子还有一个使用自定义 Java 类的例子。如果您确实需要向文件中写入内容，请使用上述代码编写您自己的实用程序，并使用com.intuit.karate.demo.util.FileChecker 作为参考。
