Workaround for using Taroutputstream to appear request to write ' 1024x768 ' bytes exceeds size in header error

Because in the test process, the client will determine the value of each parameter in the request sent to Server B according to the response returned by server A, so it is now necessary to simulate the server's response. And this Project Server A's response returns a stream, a gzip compressed format stream, which compresses multiple files, so you need to write the appropriate groovy script. I'm using Apache's Ant package here. But it went wrong when it was running. Error hints are as follows

Caught:java.io.IOException:request to write ' 1024x768 ' bytes exceeds size in header of ' 29886 ' bytes for entry ' Rate.csv '
Java.io.IOException:request to write ' 1024x768 ' bytes exceeds size in header of ' 29886 ' bytes for entry ' Rate.csv '

Literally, then carefully read the API document read (byte[] b), read (byte[] b,int off, int len), write (byte[] wbuf), write (byte[] wbuf, int woffset, in T numtowrite) After the relevant explanation, after trying, finally solved. It seems that I used to read the file and write to the file using a method of a parameter is not good habits, although there was no problem, but this time, and then the use of Read (byte[] b,int off, int len) and write (byte[] wbuf, int woffset , int numtowrite), so that this error can be prevented from happening again.
