loadrunner之WebServices协议脚本编写（三种请求模式）

以天气预报网站为例：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

一、web_service_call模式

步骤如下：

经过增加事务和if 判断的脚本如下：

Action()
{

    lr_start_transaction("获取天气预报");

    web_service_call(
         "StepName=getWeatherbyCityName_102",
        "SOAPMethod=WeatherWebService|WeatherWebServiceSoap|getWeatherbyCityName", //服务名称|soap|获取哪个接口（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=t1555506477.inf",
        BEGIN_ARGUMENTS,    //输入参数开始
        "theCityName={NewParam}",   //请求输入
        END_ARGUMENTS,        //结束参数
        BEGIN_RESULT,    //返回值得开始
        "getWeatherbyCityNameResult/*[2]=Param_string",  //返回的参数保存在Param_string
        END_RESULT,  //返回值结束
        LAST);

    if(strcmp(lr_eval_string("{NewParam}"),lr_eval_string("{Param_string}"))==){
        lr_end_transaction("获取天气预报", LR_PASS);
    }else{
        lr_end_transaction("获取天气预报", LR_FAIL);
    }

    return ;

}

二、soap_request模式 （外加查看请求报文的小插曲）

当开发只给你一个地址时，我们可以使用 soap UI 工具查看 步骤如下：

lr12 操作步骤如下：

根据城市名获取天气预报的接口文档地址：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?op=getSupportCity

脚本加上改造之后的如下：

Action()
{
    lr_convert_string_encoding(lr_eval_string("{city_name}"),NULL,"utf-8","city");
    lr_save_string(lr_eval_string("{city}"),"cityName");
   // lr_think_time(10);
    lr_start_transaction("获取天气预报");

    soap_request("StepName=SOAP Request",
        "URL=http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",
        "SOAPEnvelope="
        "<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>{cityName}</theCityName>"
                "</getWeatherbyCityName>"
            "</soap:Body>"
        "</soap:Envelope>",
        "SOAPAction=http://WebXml.com.cn/getWeatherbyCityName",
        "ResponseParam=response",
        "Snapshot=t1555573201.inf",
        LAST);

    lr_xml_get_values("XML={response}",
                      "Query=/Envelope/Body/getWeatherbyCityNameResponse/getWeatherbyCityNameResult/string[2]",
                      "ValueParam=responseValue",
                      LAST);
    lr_output_message("返回城市名称：%s",lr_eval_string("{responseValue}"));
    if(strcmp(lr_eval_string("{responseValue}"),lr_eval_string("{city_name}"))==){ //响应的参数  与参数化转码之前的参数对比
         lr_end_transaction("获取天气预报", LR_PASS);
    }else{
        lr_end_transaction("获取天气预报", LR_FAIL);
    }

    return ;
}

运行结果：

三、web_custom_request函数，创建HTTP协议完成webserive协议

脚本如下：

Action()
{
        web_custom_request("web_custom_request",
        "URL=http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",
        "Method=POST",
        "TargetFrame=",
        "Resource=0",
        "Referer=",
        "Mode=HTTP",
        "EncType=application/soap+xml; charset=utf-8",
        "Body=<?xml version=\"1.0\" encoding=\"utf-8\"?>"
"<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">"
  "<soap12:Body>"
    "<getWeatherbyCityName xmlns=\"http://WebXml.com.cn/\">"
      "<theCityName>59134</theCityName>"
    "</getWeatherbyCityName>"
  "</soap12:Body>"
"</soap12:Envelope>",
        LAST);

    return ;
}
