iPhone将xml发布到ASP.net MVC webservices

Question

是否可以从iPhone OS将XMLData发布到the服务。we服务是在带有RESTFul url的ASP.net MVC3.0中开发的，我们希望iPhone开发人员以RESTFul格式发送输入数据作为POST变量。

webservice操作结果如下所示，其中sightings是预期作为POST变量传递的参数

 public ActionResult Update(XDocument sightings)
 {
    try
    {
        XMLHelper xmlHelper = new XMLHelper();
    }
 }

这是绝对适用的，您所需要做的就是使用NSMutableURLRequest，如下所示：

NSString* sXMLToPost = @"<?xml version=\"1.0\"?><Name>user</Name>";

NSData* data = [sXMLToPost dataUsingEncoding:NSUTF8StringEncoding];

NSURL *url = [NSURL URLWithString:@"http://myurl.com/RequestHandler.ashx"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[sXMLToPost dataUsingEncoding:NSUTF8StringEncoding]];

NSURLResponse *response;
NSError *error;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

if (error) {
//handle the error
}

现在，在您的ASHX文件中，解析InputStream以读取发布的XML：

System.IO.Stream str; String strmContents;
Int32 counter, strLen, strRead;

str = Request.InputStream;

strLen = Convert.ToInt32(str.Length);

byte[] strArr = new byte[strLen];

strRead = str.Read(strArr, 0, strLen);

// Convert byte array to a text string.
strmContents = "";
for (counter = 0; counter < strLen; counter++)
{
    strmContents = strmContents + strArr[counter].ToString();            
}

请记住，您始终可以使用以下命令检查请求类型：

if (context.Request.RequestType == "POST")
