有人提问，loadrunner 上传文件搞不好，请求帮忙处理。让提供网址，用fiddler抓包上传部分，主要有3个请求

第一个请求

分析请求，请求中的cookie，是从登陆中获取到的，由于是帮忙，并且环境无法录制，就直接用web_add_cookie 来让脚本免登陆。第一个请求后会返回一些数据，这些数据要用在第二个请求中，这就需要用关联。同样，第二个请求的响应也返回一些数据，用到第三个请求中。第三个请求发送完毕，上传完成

 

lr脚本如下：

    web_reg_save_param("x-kss-newfilename-in-body", "LB=x-kss-newfilename-in-body":", "RB=}", LAST);

在做脚本时，第三个请求老是不成功，把脚本发送的请求和手动上传的请求对比，发现正常的请求有一行header请求 

Origin: https://yun.xxx.cn

于是添加一行lr代码：
    web_add_header("Origin",  "https://yun.xxx.com");

最后，代码运行通过，上传成功
