jmeter 保存响应数据

创建存放相应文件

String filepath = vars.get("RenderTradeContractFlow_resp_filepath");
log.info("----- file path :" + filepath);
//如果文件存在，则追加内容；如果文件不存在，则创建文件
File f = new File(filepath);

if(f.exists()){
    f.delete();
} else {
    File fileParent = f.getParentFile(); 
    if(! fileParent.exists()){
        fileParent.mkdirs();
    }
}
f.createNewFile();
log.info("----- success create file :" + filepath);
${__setProperty("fpp", vars.get("RenderTradeContractFlow_resp_filepath"),)};
