loadrunner关联取参--响应值unicode编码处理过

背景：做电商提交订单，需要获取订单号，然后进行支付、状态变更等操作

submitOrder()
{

    lr_think_time();

    /* 提交订单 */

/*
 specsId:规格ID，hyh_goods_specs
 phone userkey:hyh_user表中phone和user_key2 登陆用户
 userAddressId：hyh_user_address表中ID
 */

    web_reg_save_param("order",
        "LB=orderNo%22%3A%22",
        "RB=%22%7D",
        "NotFound=ERROR",
        "Search=All",
        LAST);

    web_custom_request("appapi_13",
        "URL={url}/appapi?act=submitorder",
        "Method=POST",
        "Resource=0",
        "RecContentType=text/html",
        "Referer=",
        "Snapshot=t103.inf",
        "Mode=HTTP",
        "EncType=application/json; charset=utf-8",
        "Body={'payType':'alipay','versionCode':'3.0.6','yqhCheck':'0','specsId':'516','goodsId':'100446','phone':'{phone}','comment':'','count':'1','userkey':'{userkey}','couponId':'0','userAddressId':'{addressid}'}",
        LAST);

    lr_output_message("the output is %s",lr_eval_string("{order}"));
}

成功后响应内容应该是：

{"msg":2,"msgText":"订单提交成功","orderNo":"201611151660688"} 未转码前的

实际的响应结果转码unicode

%7b%22msg%22%3a2%2c%22msgText%22%3a%22%e8%ae%a2%e5%8d%95%e6%8f%90%e4%ba%a4%e6%88%90%e5%8a%9f%22%2c%22orderNo%22%3a%22201611151660688%22%7d

看到这样的，可以用站长工具进行解码：

LR中关联参数取值，左右边界可直接放转码后的结果
