我正在尝试开发一个使用SOAP服务中的数据的应用程序。是我第一次使用SOAP服务。阅读了几本教程之后，我认为我可以以正确的方式将请求设置为服务，但是我总是在响应中出错。怎么了 ？！
NSString *soapMessage = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
"<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:ns1=\"urn:Lottery.Intf-ILottery\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:enc=\"http://www.w3.org/2003/05/soap-encoding\">\n"
"<env:Body>\n"
"<ns1:GetUpcomingLotteries env:encodingStyle=\"http://www.w3.org/2003/05/soap-encoding\">\n"
"<EntityID xsi:type=\"xsd:int\">2</EntityID>\n"
"<Password xsi:type=\"xsd:string\">Smart@Winners</Password>\n"
"<SortBy xsi:type=\"xsd:int\">0</SortBy>\n"
"<limit xsi:type=\"xsd:int\">0</limit>\n"
"</ns1:GetUpcomingLotteries>\n"
"</env:Body>\n"
"</env:Envelope>"];
NSURL *sRequestURL = [NSURL URLWithString:@"xxxxxxxxx"];
NSMutableURLRequest *myRequest = [NSMutableURLRequest requestWithURL:sRequestURL];
NSString *sMessageLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[myRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[myRequest addValue: @"urn:Lottery.Intf-ILottery/GetUpcomingLotteries" forHTTPHeaderField:@"SOAPAction"];
[myRequest addValue: sMessageLength forHTTPHeaderField:@"Content-Length"];
[myRequest setHTTPMethod:@"POST"];
[myRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:myRequest returningResponse:&response error:&error];
NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
最佳答案
下载ATTACHED PROJECT HERE
//在.h文件中
#import "TBXML.h"

if( theConnection ) {

[self showUpdating];
self.webResponseData = [NSMutableData data];
}else {
NSLog(@"Some error occurred in Connection");
[self showNetworkError];
}
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"Received Bytes from server: %lu", (unsigned long)[self.webResponseData length]);
NSString * strXml = [[NSString alloc] initWithBytes: [self.webResponseData mutableBytes] length:[self.webResponseData length] encoding:NSUTF8StringEncoding];
NSLog(@"---- %@" ,strXml);
TBXML *sourceXML = [[TBXML alloc] initWithXMLString:strXml error:nil];
TBXMLElement *rootElement = sourceXML.rootXMLElement;
TBXMLElement *entryElement = [TBXML childElementNamed:@"soap:Body" parentElement:rootElement];
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
[self.webResponseData setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[self.webResponseData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
NSLog(@"Some error in your Connection. Please try again.");
[self showNetworkError];
}
或打开FireFox
安装SOA客户端扩展
在那测试您的API
在SOA客户端中检查更新时，我得到以下标头
<?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><GetUpcomingLotteries xmlns="http://tempuri.org/"><EntityID>2</EntityID><Password>Smart@Winners</Password><SortBy>0</SortBy><limit>0</limit></GetUpcomingLotteries></soap:Body></soap:Envelope>
和以下响应（可能是服务器错误）
