LoadRunner脚本开发：接口关联和md5加密（四）

一. 关联一：登录接口依赖注册接口请求参数中的mobile

web_reg_save_param_regexp的使用

{randomPhone}的属性设置

源码：先请求注册接口，注册接口请求成功后，再去请求登录接口，登录和注册的手机号一致

Action()
    
{
    
    //定义固定参数
    lr_save_string("192.168.0.105", "host");
    lr_save_string("8080", "port");
    lr_save_string("/mobile/api", "func");
    
    
    
    //提取token值
    web_reg_save_param_regexp(
        "ParamName=register_token",
        "RegExp=token":"(.*?)"",
        "Ordinal=1",
        SEARCH_FILTERS,
        LAST);


    
    //注册接口
    web_custom_request("register",
        "URL=http://{host}:{port}{func}/user/register",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "EncType=application/json;charset=utf-8",
        "Body={"mobile":"138{randomPhone}","password":"123456","code":"3367","platform":"windows","username":"test11","sex":1,"age":20,"email":"123456@qq.com"}",
        LAST);
    
    
    
    //lr_eval_string()函数是获取值
    //如果注册成功，继续登录
    if(lr_eval_string("{register_token}")) {
           lr_output_message("===========注册成功=============");
           
           web_custom_request("login",
        "URL=http://{host}:{port}{func}/user/login",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "EncType=application/json;charset=utf-8",
        "Body={"mobile":"138{randomPhone}", "gqid":"", "password":"123456"}",
        LAST);

    } else {
           lr_output_message("===========注册失败=============");
    }


    return 0;
}

二. 关联二：充值密码接口需要登录接口的返回值token作为入参

web_reg_save_param_regexp的使用

lr_eval_string()的理解

先看个例子：如果参数 register_gqid未定义，那么gqid的值应该默认为"{register_gqid}"

Action()
{
    lr_eval_string("{register_gqid}");
    lr_save_string(lr_eval_string("{register_gqid}"), "gqid");
　  lr_output_message(lr_eval_string("{gqid}"));
    return 0;
}

那么，我们之前用这种形式判断到底对不对：if(lr_eval_string("{register_gqid}"))——这个值会不会永远是True

因为register_gqid参数是从注册接口的响应结果里匹配的，如果匹配不到，会不会采用默认值"{register_gqid}"。答案是否定的，因为register_gqid有定义，它的定义就是去响应结果里进行正则匹配，无外乎两种结果，1. 能拿到，正常进行下面的if判断，2. 拿不到，进行if判断之前就报错了，不存在默认值。这里需要区分lr_eval_string()参数有没有定义的情况

源码

Action()
    
{
    
    //定义固定参数
    lr_save_string("192.168.0.105", "host");
    lr_save_string("8080", "port");
    lr_save_string("/mobile/api", "func");
    
    
    //统计gqid出现的次数
//    web_reg_find("Text=gqid",
//                 "SaveCount=gqid_count",   
//                 LAST);
    
    

    //提取gqid值
    web_reg_save_param_regexp(
        "ParamName=register_gqid",
        "RegExp=gqid":"(.*?)"",
        "Ordinal=1",
        SEARCH_FILTERS,
        LAST);
    
    
    
    //提取登录后的token值
    web_reg_save_param_regexp(
        "ParamName=login_token",
        "RegExp=token":"(.*?)"",
        "Ordinal=1",
        SEARCH_FILTERS,
        LAST);

    
    
    //注册接口
    web_custom_request("register",
        "URL=http://{host}:{port}{func}/user/register",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "EncType=application/json;charset=utf-8",
        "Body={"mobile":"138{randomPhone}","password":"123456","code":"3367","platform":"windows","username":"test11","sex":1,"age":20,"email":"123456@qq.com"}",
        LAST);
    
    
    
    //lr_eval_string()函数是获取参数值，如果参数值不存在，则对应的字符串"{register_gqid}"，
    //因此 if(lr_eval_string("{register_gqid}"))始终为true
    //方法一：atoi()转换
    //if(atoi(lr_eval_string("{register_gqid}"))) 
    //方法二：SaveCount
    //if (atoi(lr_eval_string("{gqid_count}")) == 1)
    //如果提前定义了变量，匹配只有两种情况，1. 能匹配到，进入if判断，2. 不能匹配到，if判断前就直接抛错了，因此不存在默认值的情况。只有没有提前定义变量，才会存在默认值
    
    //if(atoi(lr_eval_string("{register_gqid}"))) {
    if(lr_eval_string("{register_gqid}")) {

           lr_output_message("===========注册成功=============");
           
           //如果注册成功，继续登录
           web_custom_request("login",
        "URL=http://{host}:{port}{func}/user/login",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "EncType=application/json;charset=utf-8",
        "Body={"mobile":"", "gqid":"{register_gqid}", "password":"123456"}",
        LAST);

    } else {
           lr_output_message("===========注册失败=============");
           return -1;
    }
    
    
    if(lr_eval_string("{login_token}")) {
        
        lr_output_message("===========登录成功================"); 
        lr_save_string(Change_to_Md5("123456_loadrunner"), "payPwd");
        
        //如果登录成功，则重置支付密码
        web_custom_request("recharge",
        "URL=http://{host}:{port}{func}/user/resetpaypwd",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "EncType=application/json;charset=utf-8",
        "Body={"token":"{login_token}", "password":"{payPwd}"}",
        LAST);

    } else {
        
        lr_output_message("===========登录失败================");
        return -1;
    }
    return 0;
}

三. md5加密：重置支付密码需要的支付密码为md5加密

引入md5.h

选中Extra Files，点击右键，出现Create New File...和Add Files to Script...

两种方式均可以，但建议选择第一种，因为第二种有可能出现乱码，第一种的做法是，新建一个md5.h文件，将md5.h中的代码拷贝进去

然后在globals.h中添加一个引入 #include "md5.h"

 真正的Action中是这样调用的：代码同上
