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
