get 方式的签名生产，困然了我2天，今天终于解决了，记录如下
var args = sampler.getArguments();
var size = args.getArgumentCount();
var argObj = {}
for(var i=0; i< size; i++) {
var name = args.getArgument(i).getName();
var value = args.getArgument(i).getValue();
log.info(name);
log.info(value);
argObj[name] = value;
}
var argsStr = JSON.stringify(argObj);
log.info(argsStr);
var s = doSign(argsStr)
log.info(s)
sampler.getArguments().removeArgument("sign");
sampler.addArgument("sign",s);
function doSign(playload){
return playload;
}
下面的知识点是关键
import org.apache.jmeter.config.Argument;
sampler.getArguments().removeArgument("page_submission_id");
sampler.addArgument("page_submission_id","8743718386872");
