转：How to POST GZip Request with Apache JMeter

 参考：https://stackoverflow.com/questions/33718462/how-to-post-gzip-request-with-apache-jmeter

1. Add HTTP Header Manager to your test plan and add at least the following headers:

   • Content-Type: application/json
   • Content-Encoding: gzip

2. Add Beanshell PreProcessor as a child of the request which you need to encode and add the following code to it's "Script" area:

   import org.apache.commons.io.IOUtils;
   import java.util.zip.GZIPOutputStream;
   
   
   String bodyString = sampler.getArguments().getArgument(0).getValue();
   byte [] requestBody = bodyString.getBytes();
   
   ByteArrayOutputStream out = new ByteArrayOutputStream(requestBody.length);
   GZIPOutputStream gzip = new GZIPOutputStream(out);
   gzip.write(requestBody);
   gzip.close();
   
   sampler.getArguments().getArgument(0).setValue(out.toString(0));
   

   It will get your request body, compress it and substitute on the fly so the request will be gzipped.
