目標c：web服務，如何講述具體的方法來訪問

Question

我試圖訪問http://services-staging.cmtnyc.com/payment/payment.asmx Web服務和

AuthorizeCreditTrip我查了.NET應用此WebService和它工作正常，但在Objective-C它不會以相同的數據作出響應。

Web服務公開5種方法，我想訪問4th。但我認爲這段代碼並沒有指定訪問的方式。 forHTTPHeaderField:@"SOAPAction"告訴我，但我不認爲它的正確鏈接放在這裏。

不響應意味着它沒有發送任何迴應。

我認爲我無法設置有效的SOAPAction

Answer 1

我用下面的代碼，並致力於對我罰款：

NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url]; 

    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]]; 
    [req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
    [req addValue:@"http://tempuri.org/SearchCustomer" forHTTPHeaderField:@"SOAPAction"]; 
    [req addValue:msgLength forHTTPHeaderField:@"Content-Length"]; 

    [req setHTTPMethod:@"POST"]; 
    [req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]]; 

其中網址我的網址，soapMsg是我的SOAP消息，@「HTTP ：//tempuri.org/Method「是肥皂行動。

Answer 2

這裏是我有工作：

NSURL *urlWS = [NSURL URLWithString:kUrlServer]; 
NSMutableURLRequest *theRequest; 
theRequest = [NSMutableURLRequest requestWithURL:urlWS]; 

NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; 
[theRequest addValue: @"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; 
[theRequest setHTTPMethod:@"POST"]; 
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; 

也許你缺少application/soap+xml。
