Iphone objective-c:Webservice，如何讲述访问的具体方法

我正在尝试访问web服务和

AuthorizeCreditTrip我在.Net应用程序上检查了此Web服务及其工作正常，但在objective-c中，它没有使用相同的数据进行响应

web服务公开了5种方法，我想访问第4种。但是我认为这段代码没有指定访问的方法

forHTTPHeaderField:@“SOAPAction”

告诉我们，但我不认为它在这里的链接是正确的

不响应意味着它不发送任何响应

我认为我无法设置有效的SOAPAction

以下是我如何让它工作的：

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]];

也许您缺少

应用程序/soap+xml

干杯

我使用了以下代码，对我来说效果很好：

    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，url是我的url，soapMsg是我的soap消息，@”http://tempuri.org/Method“是soap操作。

我建议你检查你的参数是否正确，因为你的代码看起来很好。实际上，这个web服务公开了5个方法，这个代码应该访问AuthorizeCreditTrip方法，但是这个代码没有告诉你要访问哪个函数。。我想这就是问题所在……@Azhar:你找到解决办法了吗。我也遇到了同样的问题。你能提供这个问题的答案吗。
