IOS调用webService函数获取数据的相关问题
本帖最后由 bixuemeigui 于 2012-11-30 18:12:37 编辑 开发一个IOS应用程序：需要调用WebService函数取得数据库中的数据：
数据查询接口函数为：String getReportMassage ( String startStatTime, String endStatTime, String operator, String password，String type);

下面是使用ASIHTTPRequest类调用WebService函数：

//生成soap消息函数getASISOAP11Request
-(NSString*)getASISOAP11Request:(NSString *) WebURL
                         webServiceFile:(NSString *) wsFile
                           xmlNameSpace:(NSString *) xmlNS
                         webServiceName:(NSString *) wsName
                           wsParameters:(NSMutableArray *) wsParas
{
    //1、初始化SOAP消息体
    NSString * soapMsgBody1 = [[NSString alloc] initWithFormat:
                               @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                               "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n"
                               "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"\n"
                               "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                               "<soap:Body>\n"
                               "<%@ xmlns=\"%@\">\n", wsName, xmlNS];
    
    NSString * soapMsgBody2 = [[NSString alloc] initWithFormat:
                               @"</%@>\n"
                               "</soap:Body>\n"
                               "</soap:Envelope>", wsName];
    
    //2、生成SOAP调用参数
    NSString * soapParas = [[NSString alloc] init];
    soapParas = @"";
    if (![wsParas isEqual:nil]) { 
 
        int i = 0;
        for (i = 0; i < [wsParas count]; i = i + 2) {
            soapParas = [soapParas stringByAppendingFormat:@"<%@>%@</%@>\n",
                         [wsParas objectAtIndex:i],
                         [wsParas objectAtIndex:i+1],
                         [wsParas objectAtIndex:i]];
        }
    }
    
    //3、生成SOAP消息
    NSString * soapMsg = [soapMsgBody1 stringByAppendingFormat:@"%@%@", soapParas, soapMsgBody2];
    NSLog(@"%@",soapMsg);
    return soapMsg;
    }
//发送Soap消息
-(void)ServiceRequestUrl:(NSString*)WebURL ServiceMethodName:(NSString*)strMethod SoapMessage:(NSString*)soapMsg{
//请求发送到的路径
    NSURL * url = [NSURL URLWithString:[NSString stringWithFormat:@"%@", WebURL]];

    //NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    //[theRequest setURL:url];
   theRequest= [ASIHTTPRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]];

    //以下对请求信息添加属性前四句是必有的，第五句是soap信息。
[theRequest addRequestHeader:@"Host" value:[url host]];
    [theRequest addRequestHeader:@"Content-Type" value:@"text/xml; charset=utf-8"];
[theRequest addRequestHeader:@"Content-Length" value:msgLength];
    [theRequest addRequestHeader:@"SOAPAction" value:[NSString stringWithFormat:@"%@%@",defaultWebServiceNameSpace,strMethod]];
    [theRequest setRequestMethod:@"POST"];
//传soap信息
    [theRequest appendPostData:[soapMsg dataUsingEncoding:NSUTF8StringEncoding]];
    [theRequest setValidatesSecureCertificate:NO];
    //[theRequest setTimeOutSeconds:60.0];
    [theRequest setDefaultResponseEncoding:NSUTF8StringEncoding];

//return theRequest;
}

#pragma -
#pragma 同步请求
//返回数据
-(NSString*)SysServiceUrl:(NSString*)strUrl ServiceMethodName:(NSString*)strMethod SoapMessage:(NSString*)soap
{
    ASIHTTPRequest *request=[self requestServiceUrl:strUrl ServiceMethodName:strMethod SoapMessage:soap];
 [request startSynchronous];
    NSError *error=[request error];
    int statusCode = [request responseStatusCode];
    NSLog(@"%d",statusCode);
    if (error||statusCode!=200) {
               return @"";
       
    }
   return [SoapXmlParseHelper SoapMessageResultXml:[request responseString] ServiceMethodName:strMethod]; 
 
}
//发送请求，获取数据
- (void)sender: (id) sender {   
    NSString *startStatTime =[NSString stringWithFormat:@"20121120"];
    NSString *endStatTime =[NSString stringWithFormat:@"20121130"];
    NSString *Operator =[NSString stringWithFormat:@"800001"];
    NSString *password =[NSString stringWithFormat:@"E10ADC3949BA59ABBE56E057F20F883E"];
    NSString *type =[NSString stringWithFormat:@"01"];
    NSMutableArray *paras=[[NSMutableArray alloc]
initWithObjects:@"startStatTime",startStatTime,@"endStatTime",endStatTime,@"operator" ,Operator,@"password",password,@"type",type,nil];
  
//调用函数 
    NSString *soapMsg =[self getASISOAP11Request:@"http://192.168.86.230:8088/dvteboss_ws/wsservice/" webServiceFile:@"ReportWS" xmlNameSpace:@"http://tempuri.org/" webServiceName:@"getReportMassage" wsParameters:paras];
    
    ServiceHelper* service =[[ServiceHelper alloc] init]; 
    NSString* requestString = [service SysServiceUrl:@"http://192.168.86.230:8088/dvteboss_ws/wsservice/ReportWS" ServiceMethodName:@"getReportMassage" SoapMessage:soapMsg]; 
    
    NSLog(@"%@",requestString);         
}

返回的是一个网页的源代码，并没有返回我想要的XML文件，请问这是为什么啊，是我请求发送出现问题了吗？



求高手指教！！！！！！！！！！！

[解决办法]
帮你顶一下，没做过WebService..
[解决办法]
抓过包看看请求头，各部分符合不
[解决办法]
有条件你可以抓一下android发的包，和ios发的包对比一下就清楚了，
[解决办法]
一般前两个方法没有什么大问题，有问题就是后面的两个方法，望lz耐心调试，看看你的webservice可行不？
[解决办法]
怎么看的这样混乱呢，
使用CWHessianArchiver 几行代码搞定的东西啊
NSURL *url = [NSURL URLWithString:ADDRESS];
id<HessianService> ts = (id<HessianService>)[CWHessianConnection proxyWithURL:url protocol:@protocol(HessianService)];
[CWHessianArchiver setMethodName:@"getReportMassage" forSelector:@selector(getReportMassage:endStatTime:operator:password:type:)];
NSString* returnXml = [ts getReportMassage:@"" endStatTime:@"" operator:@"" password:@"" type:@""];
