请求格式无效：text/xml; charset = utf-8

问题描述：

我是iphone开发新手。请求格式无效：text/xml; charset = utf-8

我想从iphone应用程序发送NSSTRING到服务器。

有了下面的代码

线

NSString *soapMessage = [NSString stringWithFormat: 
          @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" 
          "<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" 
          "<soap12:Body>\n" 
          "<SaveData xmlns=\"http://tempuri.org/\">\n" 
          "<xmlstring>%@</xmlstring>\n" 
          "</SaveData>\n" 
          "</soap12:Body>\n" 
          "</soap12:Envelope>\n", StringXml 
          ]; 
    NSLog(@"Soap Messaage......%@",soapMessage); 

    NSURL *url = [NSURL URLWithString:urlString]; 
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url]; 
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; 

    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
    [theRequest addValue: @"http://tempuri.org/SaveData" forHTTPHeaderField:@"SOAPAction"]; 
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; 
    // [theRequest addValue: StringXml forHTTPHeaderField:@"xmlstring"]; 
    [theRequest setHTTPMethod:@"POST"]; 
    [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; 
    //[theRequest setHTTPBody: [StringXml dataUsingEncoding:NSUTF8StringEncoding]]; 

    NSURLConnection *connectionResponse = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

但回到我的错回复

即

System.InvalidOperationException：请求格式无效：文本/ XML;字符集= UTF-8。在System.Web.Services.Protocols.HttpServerProtocol.ReadParameters（）在System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest（）

如何在来到这个问题？

显示代码用于接收数据.. – AppleDelegate

后 - （无效）连接：（NSURLConnection的*）连接didReceiveResponse：（NSURLResponse * ）响应 {} - （void）connection：（NSURLConnection *）connection didReceiveData：（NSData *）data {NSMutableData * webdata = [[NSMutableData alloc] initWithData：data]; NSString * theXML = [[NSString alloc] initWithBytes：[webdata mutableBytes] length：[webdata length] encoding：NSUTF8StringEncoding]; NSLog（@“received theXML：％@”，theXML）; } - （无效）连接：（NSURLConnection的*）连接didFailWithError：（NSError *）错误 {的NSLog（@ “用theConenction ERROR”）;} - （无效）connectionDidFinishLoading：（NSURLConnection的*）连接 {} –

答

不要使用NSURLConnection的只是设置肥皂envelope..use这个代替

NSError *WSerror; 
     NSURLResponse *WSresponse; 

     @try 
     { 

     NSMutableData *resMutableData = (NSMutableData *)[NSURLConnection sendSynchronousRequest:theRequest returningResponse:&WSresponse error:&WSerror]; 


      NSString *theResponse = [[NSString alloc]initWithBytes:[resMutableData mutableBytes] length:[resMutableData length] encoding:NSUTF8StringEncoding]; 
      NSLog(theResponse); 

     } 
     @catch(NSException* ex) 
     { 
      NSLog(@"Webservice Request Failed: Error %@", [WSerror code]); 
     }

以为我又得到了同样的错误。我已经在safari上检查了我的网址。它给出了正确的答复。但我的代码不能。 –

你在哪里使用了你的文件中的上述代码？ – AppleDelegate

在我的应用程序中的UIViewController.m文件中 –
