无法从iPhone连接到基于soap的wcf服务

Question

我正试图使用iPhone应用程序中的SOAP web服务，但在与Charles进行检查时出现以下错误：

值不能为null ；参数名称：s

以下是我的代码：

NSString *soapMessage = [NSString stringWithFormat:@"<?xml version="1.0" encoding="utf-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><updateTimesheet><TimeSheetHourID>222</TimeSheetHourID></updateTimesheet></SOAP-ENV:Body></SOAP-ENV:Envelope>"];
NSURL *url = [NSURL URLWithString:@"http://172.xx.xxx.xx:xxxx/postService.svc/basic"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];

NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
NSLog(@"Message Length..%@",msgLength);
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"urn:IpostService/updateTimesheet" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[NSError alloc] init];
//NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
NSData *responseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&urlResponse error:&error];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) {
    NSLog(@"Response: %@", result);
    //here you get the response 
}

我得到错误代码500作为响应。有人能帮我吗？

谢谢

Answer 1

错误500是-内部服务器错误。这意味着——服务器遇到意外情况，无法完成请求。

请确保向服务器发送了正确的请求。你能在其他地方消费吗？

问题不在于您的代码。。我建议您跟踪Web服务代码。
