ios-Soap方法通过http post请求调用，但响应为空

Question

xxI是iPhone新手。在我的应用肥皂方法 使用导入和导出data..while进口工作不错，但出口不工作从SOAP网络服务的响应是空的..

//参数

NSString *cust=@"<NEWCUSTOMERS><NEWCUSTOMER></NEWCUSTOMER></NEWCUSTOMERS>"; 
    NSString *trans=@"<TRANS><TRAN></TRAN></TRANS>"; 
    NSString *RETURNS=@"<RETURNS><RETURN></RETURN></RETURNS>"; 
    NSString *prepayment=@"<PREPAYMENTS><PREPAYMENT></PREPAYMENT></PREPAYMENTS>"; 
    NSString *receipt=@"<RECEIPTS><RECEIPT></RECEIPT></RECEIPTS>"; 
    NSString *spcode1=@"BB"; 
    NSString *companyShortName=@"Sample Company Limited"; 
    NSString *companyCode=@"01"; 

//肥皂网址：

NSURL *url = [NSURL URLWithString:@"http://xxx.xxx.xxx.xx/SAAP/SOAP.asmx"]; 

// SOAP Methos：

NSString *soapMsg=[NSString stringWithFormat:@"<?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>" 
         "<PostXMLStr xmlns=\"http://tempuri.org/\">" 
         "<cust>%@</cust>" 
         "<tran>%@</tran>" 
         "<ret>%@</ret>" 
         "<ppay>%@</ppay>" 
         "<recp>%@</recp>" 
         "<sCode>%@</sCode>" 
         "<companyShortName>%@</companyShortName>" 
         "<companyCode>%@</companyCode>" 
         "</PostXMLStr>" 
         "</soap:Body>" 
         "</soap:Envelope>",cust,trans,RETURNS,prepayment,receipt,spcode1,companyShortName,companyCode]; 

    NSMutableURLRequest *requests = [[NSMutableURLRequest alloc] initWithURL:url]; 
    NSLog(@"soapMsg= %d soapMsg=%@",soapMsg.length,soapMsg); 
    NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMsg length]]; 
    NSLog(@"msgLength=%@ ",msgLength); 

    [requests addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
    [requests addValue:@"chunked" forHTTPHeaderField:@"transfer-coding"]; 
    [requests addValue:msgLength forHTTPHeaderField:@"Content-Length"]; 
    [requests setValue:@"http://tempuri.org/PostXMLStr" forHTTPHeaderField:@"SOAPAction"]; 
    [requests setHTTPMethod:@"POST"]; 

    [requests setHTTPBody:[soapMsg dataUsingEncoding:NSUTF8StringEncoding]]; 
    // [requests setHTTPBodyStream:dataStream]; 
    //[requests setTimeoutInterval:2000]; 
    NSLog(@"request=%@",requests); 

    NSURLResponse *response; 
    NSError *error = nil; 

//强大的文本：

NSMutableData *data =[[NSMutableData alloc]init]; 
    data =(NSMutableData *) [NSURLConnection sendSynchronousRequest:requests returningResponse:&response error:&error]; 

//[NSURLConnection connectionWithRequest:requests delegate:self]; 
    //NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:requests delegate:self startImmediately:YES]; 
    //NSURLConnection *connection=[NSURLConnection connectionWithRequest:requests delegate:self]; 


NSLog(@"requestdata=%@",data); 
    stringSoap = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
    NSDictionary *headers = [(NSHTTPURLResponse *)response allHeaderFields]; 
    NSLog(@"data %@",headers); 
    NSLog(@"error %@ data str %@ resulString=%@",error,stringSoap,resulString); 

//从SOAP方法结果：有数据str是空的响应..

}

请帮我...

有没有可能是你的Transfer-Coding:chunked头被混淆服务器，并因此无法处理您的数据？你知道Content-Length，所以显然不需要大块发送数据，我认为你无论如何都可以用NSURLConnection这样做。
