Question

创建了一个扩展名为.php的Web服务，我通过soap传递参数。但它的回报是出于我的理解。我还使用正确的输入检查RestClient，然后返回实际输出。这在代码中没有正确进行。可能出了什么问题？

输入的xml结构是，

<?xml version="1.0" encoding="utf-8"?>
<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/">
 <soap:Header>
 </soap:Header>
 <soap:Body>
   <getUpdates>
  <user_location></user_location>
  <application_type>FC</application_type>
  <last_updated_date>2014-11-25</last_updated_date>
  <platform>Android</platform>
  </getUpdates>
 </soap:Body>
</soap:Envelope>

我的网络服务方法是，

-(void) notifyDatacalled
{

    NSString * post= @"<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/\"><soap:Header></soap:Header><soap:Body><getUpdates><user_location>new york</user_location><application_type>free</application_type><last_updated_date>2014-12-12</last_updated_date><platform>ios</platform></getUpdates></soap:Body></soap:Envelope>";


    NSURL *url = [NSURL URLWithString:@"http://game.techone.com/webservices/service.php"];

    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    [request setTimeOutSeconds:30];
    [request setDelegate:self];
    [request setPostBody:[[post dataUsingEncoding:NSUTF8StringEncoding] mutableCopy]];
    [request addRequestHeader:@"Content-Type" value:@"text/xml"];
    [request addRequestHeader:@"Content-Length" value:[NSString stringWithFormat:@"%d",[post length]]];
    [request addRequestHeader:@"SOAPAction" value:@"getUpdates"];
    [request setPostLength:[post length]];
    [request setRequestMethod:@"POST"];
    [request startSynchronous];

    NSError *error = [request error];
    if (error)
    {

    }
    else
    {
           NSString *XmlResult = [NSString stringWithFormat:@"%@",[request responseString]];
            NSDictionary *dictioneryResult = [XMLReader dictionaryForXMLString:XmlResult error:nil];
  }
}

我得到的回应是，

"SOAP-ENV:Envelope" =     {
        "SOAP-ENV:Body" =         {
            "ns1:getUpdatesResponse" =             {
                return =                 {
                    "SOAP-ENC:arrayType" = "xsd:anyType[0]";
                    "xsi:type" = "SOAP-ENC:Array";
                };
                "xmlns:ns1" = "http://schemas.xmlsoap.org/soap/envelope/";
            };
        };
        "SOAP-ENV:encodingStyle" = "http://schemas.xmlsoap.org/soap/encoding/";
        "xmlns:SOAP-ENC" = "http://schemas.xmlsoap.org/soap/encoding/";
        "xmlns:SOAP-ENV" = "http://schemas.xmlsoap.org/soap/envelope/";
        "xmlns:xsd" = "http://www.w3.org/2001/XMLSchema";
        "xmlns:xsi" = "http://www.w3.org/2001/XMLSchema-instance";
    };

尝试添加

[request addRequestHeader:@"Accept" value:@"text/xml"];

到您的网络服务请求。您正在调用的REST服务默认为json。许多人经常根据请求返回XML。
