LR做webservices协议

获取天气的url地址：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?op=getWeatherbyCityName
第一种方法：
1.在lr12里新建一个Web Services协议的项目
2.点击manage services
点击import，选择URL填写url地址信息

		lr_start_transaction("获取天气预报");

	web_service_call( 
		"StepName=getWeatherbyCityName_101",//步骤名称
		"SOAPMethod=WeatherWebService|WeatherWebServiceSoap|getWeatherbyCityName",//调用的一些服务的名称|soap|请求的方法获取哪个接口（城市天气预报）
		"ResponseParam=response",//返回的参数信息
		"Service=WeatherWebService",//webservice的服务
		"ExpectedResponse=SoapResult",//请求的返回信息
		"Snapshot=t1555506334.inf",//快照
		BEGIN_ARGUMENTS,//开始输入参数
		"theCityName={city_name}",//请求输入的数据，城市={city_name}
		END_ARGUMENTS,//结束参数的输入
		BEGIN_RESULT,//返回值的开始
		"getWeatherbyCityNameResult/*[1]=Param_string",//返回的参数保存在Param_string里面，[1]是数组的下标
		END_RESULT,//返回值的结束
		LAST);
		if(strcmp(lr_eval_string("{Param_string}"),lr_eval_string("{city_name}"))==0)
		{
			lr_end_transaction("获取天气预报",LR_PASS);
		}
		else
		{
			lr_end_transaction("获取天气预报",LR_FAIL);
		}

第二种方法
1.先把请求数据存放到记事本里，改后缀为xml
2.lr里
导入刚刚的xml文件
3.

	lr_convert_string_encoding("厦门",NULL,"utf-8","cityname");//将中文的utf-8转换成lr的编码方式
	//lr_convert_string_encoding（lr_eval_string
	lr_save_string(lr_eval_string("{cityname}"),"city_name");//把cityname保存给city_name
	soap_request("StepName=SOAP Request",		//步骤的名称								
		"URL=http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",		//请求的url								
		"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>{city_name}</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的名称								
		"Snapshot=t1555509167.inf",									    
		LAST);
	lr_convert_string_encoding(lr_eval_string("{response}"),"utf-8",NULL,"msg");
	//通过这个函数来获取参数值
	lr_xml_get_values("XML={response}",
		 "Query=/Envelope/Body/getWeatherbyCityNameResponse/getWeatherbyCityNameResult/string[2]",//对输入字符串xml的查找或快速查找，指定元素或属性
	                  "ValueParam=city_code",//存储查询结果的输出参数的名称
	                  LAST);
	lr_output_message("返回的城市名称:%s",lr_eval_string("{city_code}"));

第三种方法
忘记了可以用检查点来做if判断
复习了检查点，后续要慢慢看视频补充笔记到博客

Action()
{
	lr_convert_string_encoding(lr_eval_string("{city_name_value}"),NULL,"utf-8","cityname");
	lr_save_string(lr_eval_string("{cityname}"),"city_name");//把cityname保存给city_name
	
	lr_start_transaction("获取天气预报");
	//根据城市名称做检查点
	web_reg_find("Search=Body",
		"SaveCount=city_name_count",//统计检查点的次数
		"Text={city_name}",//要检查的参数
		LAST);
	web_custom_request("web_custom_request",
		"URL=http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",
		"Method=POST",
		"TargetFrame=",//fram名称
		"Resource=0",
		"Referer=",
		"Mode=HTTP",
		"EncType=text/xml; charset=utf-8",
		"BodyBinary=<?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>{city_name}</theCityName>"
   " </getWeatherbyCityName>"
  "</soap:Body>"
"</soap:Envelope>",
		LAST);
	//atoi：指定的字符转换成整型
	//lr_eval_string：获取当前参数的值
	if(atoi(lr_eval_string("{city_name_count}"))>=1)
	{
	   	lr_end_transaction("获取天气预报",LR_PASS);
	}
	else
	{
		lr_end_transaction("获取天气预报",LR_FAIL);
	}
	
	return 0;
}
