lr-web services协议

1、web services协议简介

   web services协议是建立可交互操作的分布式应用程序的新平台,它通过一系列标准和协议来保证程序之间的动态链接,其中最基本的协议包括soap,wsdl,uddi。

2、若开发只给了一个webservices的url,未提供报文请求格式,要怎么操作?http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

      用soap ui工具可获得

 1)新建soap项目,命名且输入wsdl url,点击ok即可;

2)可查看到该url下的所有接口,双击你要查看的接口名,就可以在右边窗口查看到响应的请求报文;

3、loadrunner操作

创建web services脚本,以获取天气预报服务为例;http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

a、此次运用了三个模式来创建脚本请求:web_service_call、soap_request、web_custom_request

b、请求中带中文,不转码导致得到的响应非所期望的,此时需要转码,如下:

          lr_convert_string_encoding("深圳",NULL,"utf-8","cityname");
          lr_save_string(lr_eval_string("{cityname}"),"cityname");

c、响应中由于有中文显示出为乱码,转码如下: 

         lr_convert_string_encoding(lr_eval_string("{response}"),"utf-8",NULL,"msg");

d、若响应时一个xml,可用lr_xml_get_values()

例:lr_xml_get_values("XML={response}",
        "Query=/Envelope/Body/getWeatherbyCityNameResponse/getWeatherbyCityNameResult/string[2]",
                      "ValueParam=getcityname",
                      LAST);

web_service_call模式:

1)在SOA Tools中选中Manage Services

2)导入url地址

3)直接点击ok

4)在SOA Tools里点击add service call

 5)选择好服务名、接口和soap,再填写输入参数

6)填写输出参数名

点击ok后,在loadrunner里生成了web_service_call请求;

对脚本请求做修改,添加事物、if判断,脚本如下:

     Action()
{
        lr_start_transaction("获取天气预报城市名");
        web_service_call( "StepName=getWeatherbyCityName_101",//步骤名称 
        "SOAPMethod=WeatherWebService|WeatherWebServiceSoap|getWeatherbyCityName",//服务名称 soap  获取那个接口 (城市天气预报) 
        "ResponseParam=response",//返回的参数信息 
        "Service=WeatherWebService",//webservice的服务 
        "ExpectedResponse=SoapResult",//请求的返回
        "Snapshot=t1555823842.inf",//快照 
        BEGIN_ARGUMENTS,//输入参数 开始 
        "theCityName={cityname}",//请求输入,城市=深圳或者其它城市名称 
        END_ARGUMENTS,//结束参数 
        BEGIN_RESULT,//返回值的开始 
        "getWeatherbyCityNameResult/*[2]=Param_string",//返回参数保存在Param_string
        END_RESULT,//返回值 的结束 
        LAST);
        if (strcmp(lr_eval_string("{Param_string}"),lr_eval_string("{cityname}"))==0)
        {
        lr_end_transaction("获取天气预报城市名", LR_PASS);
        }
        else
        {
        lr_end_transaction("获取天气预报城市名", LR_FAIL);
        }
        
    return 0;
}

soap request模式:

1)在SOA Tools下选中import SOAP;

2)选中soap的xml文件,根据例子,填写好url和soap actions;

 3)点击ok,生成一个soap_request请求在脚本里;

4)修改脚本,添加if判断,脚本如下:

Action()
{
    lr_convert_string_encoding(lr_eval_string("{getcity}"),NULL,"utf-8","cityname");
    lr_save_string(lr_eval_string("{cityname}"),"cityname1");
    lr_start_transaction("获取城市天气预报");
    soap_request("StepName=SOAP Request",    //步骤名称                                     
        "URL=http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",//请求的url地址                                         
        "SOAPEnvelope="//发送到服务器的xml包 
        "<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">"
            "<soap:Body>"
                "<getWeatherbyCityName xmlns="http://WebXml.com.cn/">"
                    "<theCityName>{cityname1}</theCityName>"
                "</getWeatherbyCityName>"
            "</soap:Body>"
        "</soap:Envelope>",                                        
        "SOAPAction=http://WebXml.com.cn/getWeatherbyCityName",                                        
        "ResponseParam=response",    //存储服务器 响应的输出参数名称                                     
        "Snapshot=t1555845699.inf",                                        
        LAST);

    //lr_convert_string_encoding(lr_eval_string("{response}"),"utf-8",NULL,"msg");
    //lr_output_message("msg结果:%s",lr_eval_string("{msg}"));
    lr_xml_get_values("XML={response}",
        "Query=/Envelope/Body/getWeatherbyCityNameResponse/getWeatherbyCityNameResult/string[2]",
                      "ValueParam=getcityname",
                      LAST);

    if (strcmp(lr_eval_string("{getcityname}"),lr_eval_string("{getcity}"))==0)
        {
        lr_end_transaction("获取城市天气预报", LR_PASS);
        lr_output_message("获取指定城市天气成功");
        }
        else
        {
        lr_end_transaction("获取城市天气预报", LR_FAIL);
        lr_output_message("获取指定城市天气失败");
        }
    
    return 0;
}

web_custom_request模式:

1)此模式较简单,与http协议post请求方法一致:

2)脚本Action()

{
    lr_convert_string_encoding(lr_eval_string("{getcity}"),NULL,"utf-8","cityname0");
    lr_save_string(lr_eval_string("{cityname0}"),"cityname1");
    web_reg_save_param_ex(
        "ParamName=recityname",
        "LB=<string>",
        "RB=</string>",
        "Ordinal=ALL",
        SEARCH_FILTERS,
        LAST);
    lr_start_transaction("获取城市天气预报");

    
    web_custom_request("web_custom_request",
        "URL=http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "Mode=HTTP",
        "EncType=text/xml; charset=utf-8",
        "Body=<?xml version="1.0" encoding="utf-8"?>"
"<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">"
  "<soap:Body>"
    "<getWeatherbyCityName xmlns="http://WebXml.com.cn/">"
      "<theCityName>{cityname1}</theCityName>"
    "</getWeatherbyCityName>"
  "</soap:Body>"
"</soap:Envelope>",
        LAST);
    lr_convert_string_encoding(lr_eval_string("{recityname_2}"),"utf-8",NULL,"recityname_2");
    lr_save_string(lr_eval_string("{recityname_2}"),"recityname");
    if (strcmp(lr_eval_string("{recityname}"),lr_eval_string("{cityname}"))==0)
    {
        lr_end_transaction("获取城市天气预报", LR_PASS);
        lr_output_message("获取城市天气预报成功");

    }
    else
    {
        lr_end_transaction("获取城市天气预报", LR_PASS);
        lr_error_message("获取城市天气预报失败");
    }

    return 0;
}
