Question

我正在尝试开发这个可以与本地网络下的C＃Web服务进行通信的iOS应用程序。我正在使用AFNetworking来实现沟通。现在，我已经在this tutorial的帮助下从Web服务中读取了xml数据，这意味着我的应用程序可以连接到Web服务。但我真正想要做的是，将数据从应用程序传递到Web服务。我写了一些示例代码：

AFmyAPIClient *myClient = [AFmyAPIClient sharedClient];
NSMutableDictionary *requestArray = [NSMutableDictionary new];
NSString *details = [_listOfItems description];
float tempF= [_listOfItems totalPrice];
NSString *price = [NSString stringWithFormat:@"%f",tempF];
int tempI = 1;
NSString *table = [NSString stringWithFormat:@"%u",tempI];

[requestArray setObject:details forKey:@"details"];
[requestArray setObject:price forKey:@"price"];
[requestArray setObject:table forKey:@"table"];

[myClient postPath:@"setOrderDetails" parameters:requestArray success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"success!");
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"%@",error);
    }];

构建并运行此应用程序后，它会生成以下错误消息：

2013-11-03 16:25:48.654 HLR[16149:70b] <?xml version="1.0" encoding="utf-8"?>

    "Content-Length" = 34;
    "Content-Type" = "text/plain; charset=utf-8";
    Date = "Sun, 03 Nov 2013 05:25:34 GMT";
    Server = "Microsoft-IIS/7.5";
    "X-AspNet-Version" = "2.0.50727";
    "X-Powered-By" = "ASP.NET";
} }}

在我的C＃Web服务方面，我有以下Web方法：

[Web Method]
public void setOrderDetails(String orderDetails)
{
         //store orderDetails into a text file.

}

我是iOS开发的新手，我不明白在调用此方法时我真正传递给Web服务的是什么：

[myClient postPath:@"setOrderDetails" parameters:requestArray success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSLog(@"success!");
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"%@",error);
        }];

我是否只是将NSDictionary作为参数传递给C＃Web服务？如果是这样的话，我可以在Web服务端使用这个NSDictionary做什么？

我不知道这是否是将数据传递到Web服务的正确方法。我真正想要做的是将一些字符串传递给Web服务，我该如何实现呢？

任何建议都将不胜感激！

您将XML内容作为URL参数传递。您需要在请求的正文中传递它。以下是使用AFNetworking发布XML的几个问题：
