iOS 上的 SOAP 不工作

Question

我对 SOAP 很陌生，所以不要介意我的愚蠢。 我有一个 SOAP Web 服务，位于 http://207.7.208.250:31361/SSI_MOBILE_PROD_INQ

WSDL 如下

这就是我正在做的事情来获取...... 我想发送 UPC 代码并检索生成的 xml，然后我将解析并检索数据。

NSMutableString *sRequest = [[NSMutableString alloc] init];
        [sRequest appendString:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"];
        [sRequest appendString:@"<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/\">"];
    [sRequest appendString:@"<soap:Body>"];
    [sRequest appendString:@"<SSI_MOBILE_PROD_INQ xmlns=\"http://207.7.208.250:31361/SSI_MOBILE_PROD_INQ/\">"];
    [sRequest appendString:@"<CALL_SSI_MOBILE_PROD_INQ>"];
    [sRequest appendString:@"<UPC>"];
    [sRequest appendString:@"78285630648"];
    [sRequest appendString:@"</UPC>"];
    [sRequest appendString:@"</CALL_SSI_MOBILE_PROD_INQ>"];
    [sRequest appendString:@"</SSI_MOBILE_PROD_INQ>"];
    [sRequest appendString:@"</soap:Body>"];
    [sRequest appendString:@"</soap:Envelope>"];

    NSURL *weatherServiceURL = [NSURL URLWithString:@"http://207.7.208.250:31361/SSI_MOBILE_PROD_INQ"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:weatherServiceURL];

    [request addValue:@"text/xml; charset:UTF-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue:@"http://207.7.208.250:31361/SSI_MOBILE_PROD_INQ" forHTTPHeaderField:@"SOAPAction"]; 

    [request setHTTPMethod:@"POST"];

    [request setHTTPBody:[sRequest dataUsingEncoding:NSUTF8StringEncoding]];

    NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    if (conn) {
        myMutableData = [NSMutableData data];
        NSLog(@"Conn is true");
    }
    [NSURLConnection connectionWithRequest:request delegate:self];

    NSError *WSerror;
    NSURLResponse *WSresponse;

    NSData *returnData = (NSMutableData*)[NSURLConnection sendSynchronousRequest:request
                                          returningResponse:&WSresponse error:&WSerror];
if(WSerror){
     NSLog(@"%@", [WSerror localizedDescription]);
 }
if (returnData) {

    NSString *content = [NSString stringWithUTF8String:[myMutableData bytes]];
    DebugLog(@"yeah %@", content);
}

我没有从内容字符串中得到任何输出。 我想我没有正确调用 SOAP 方法......？ 你有什么想法？

Answer 1

我发现您的代码存在一些问题：

NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[NSURLConnection connectionWithRequest:request delegate:self];
NSData *returnData = (NSMutableData*)[NSURLConnection sendSynchronousRequest:request
                                          returningResponse:&WSresponse error:&WSerror];

connectionWithRequest:delegate:
创建并返回已初始化的 URL 连接，并开始加载 URL 请求的数据。

initWithRequest:委托：
返回一个初始化的 URL 连接并开始加载 URL 请求的数据。

sendSynchronousRequest:returningResponse:错误：
执行指定 URL 请求的同步加载。

请参阅： NSURLConnection 类参考< /a>

你为什么用同样的方法做这三个事情？两个异步 URL 连接和一个同步连接。

强烈建议不要在主线程上使用 sendSynchronousRequest。

您只需要一个 URL Connection 对象来发送 URL 请求的异步加载。注释掉之后的其余部分：

if (conn) {
        myMutableData = [NSMutableData data];
        NSLog(@"Conn is true");
    } 

Change myMutableData = [NSMutableData data]; myMutableData = [[NSMutableData alloc] init];

并实现 NSURLConnectionDelegate 方法来接收异步回调：

-(NSCachedURLResponse *)connection:(NSURLConnection *)connection
                 willCacheResponse:(NSCachedURLResponse *)cachedResponse
{
  return nil;
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
   NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
   NSInteger statusCode = [httpResponse statusCode];
   NSLog(@"Http Status Code: %i",statusCode);
   if ([response respondsToSelector:@selector(statusCode)])
{
  int statusCode = [((NSHTTPURLResponse *)response) statusCode];
  if (statusCode >= 400)
  {
    [connection cancel];  // stop connecting; no more delegate messages
    NSDictionary *errorInfo
      = [NSDictionary dictionaryWithObject:[NSString stringWithFormat:
          NSLocalizedString(@"Server returned status code %d",@""),
            statusCode]
                                    forKey:NSLocalizedDescriptionKey];
    NSError *statusError
      = [NSError errorWithDomain:@"HTTP Error"
                            code:statusCode
                        userInfo:errorInfo];
    [self connection:connection didFailWithError:statusError];
  }
}
   [myMutableData setLength:0];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
   [myMutableData appendData:data];
}

- (void)connection:(NSURLConnection *)connection
  didFailWithError:(NSError *)error
{
   NSLog(@"Connection failed! Error - %@ %@",
          [error localizedDescription],
          [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]);
   connection = nil;
   [myMutableData release],myMutableData = nil;
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
   NSString *result =[[NSString alloc]initWithData:myMutableData encoding:NSUTF8StringEncoding];   
   NSLog(@"downloaded output  %@",result);

   [result release];
   [myMutableData release],myMutableData = nil;     
}
