Question

我正在尝试使用肥皂网服务，它只返回一个日期（测试）。但我无法连接Web服务。我只是从Web服务接收wsdl但我无法获得所需的数据。以下是我在目标c中的代码

 NSString *soapMessage = @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<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/\">\n"
"<soap:Body>\n"
"<getDate xmlns:type=\"xsd:string\">\n"
"</getDate>\n"
"</soap:Body>\n"
"</soap:Envelope>\n";
NSURL *url = [NSURL URLWithString:@"http://10.1.6.5/gnosis2/public/wslogin/"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[req addValue:@"text/xml; charset=utf-8"  forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://10.1.6.5/gnosis2/public/wslogin/" forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:req delegate:self];

我想从Web服务中使用getDate方法。有人可以帮帮我吗？

修改
上面的代码给了我以下xml，它与在浏览器中查看的wsdl相同：

<?xml version="1.0"?><definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://10.1.6.5/gnosis2/public/wslogin/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="MyWebService" targetNamespace="http://10.1.6.5/gnosis2/public/wslogin/"><types><xsd:schema targetNamespace="http://10.1.6.5/gnosis2/public/wslogin/"/></types><portType name="MyWebServicePort"><operation name="getDate"><documentation>Get the server date and time</documentation><input message="tns:getDateIn"/><output message="tns:getDateOut"/></operation><operation name="getAgeString"><documentation>Get a nicely formatted string of a person's age</documentation><input message="tns:getAgeStringIn"/><output message="tns:getAgeStringOut"/></operation></portType><binding name="MyWebServiceBinding" type="tns:MyWebServicePort"><soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/><operation name="getDate"><soap:operation soapAction="http://10.1.6.5/gnosis2/public/wslogin/#getDate"/><input><soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://10.1.6.5/gnosis2/public/wslogin/"/></input><output><soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://10.1.6.5/gnosis2/public/wslogin/"/></output></operation><operation name="getAgeString"><soap:operation soapAction="http://10.1.6.5/gnosis2/public/wslogin/#getAgeString"/><input><soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://10.1.6.5/gnosis2/public/wslogin/"/></input><output><soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://10.1.6.5/gnosis2/public/wslogin/"/></output></operation></binding><service name="MyWebServiceService"><port name="MyWebServicePort" binding="tns:MyWebServiceBinding"><soap:address location="http://10.1.6.5/gnosis2/public/wslogin/"/></port></service><message name="getDateIn"/><message name="getDateOut"><part name="return" type="xsd:string"/></message><message name="getAgeStringIn"><part name="name" type="xsd:string"/><part name="age" type="xsd:int"/></message><message name="getAgeStringOut"><part name="return" type="xsd:string"/></message></definitions>

请仔细阅读以下链接http://www.icodeblog.com/2008/11/03/iphone-programming-tutorial-intro-to-soap-web-services/

非常简单的方法是生成WSDL类。可以使用https://code.google.com/p/wsdl2objc/执行此操作。遵循https://code.google.com/p/wsdl2objc/wiki/UsageInstructions

的指示

以下代码块帮助我使用SOAP请求处理Web服务。

-(void)getWebServiceContent {

    NSURL *url = [NSURL URLWithString:@"http://url_value_here"];
    NSString *soapBody = @"soap_body_here";

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPBody:[soapBody dataUsingEncoding:NSUTF8StringEncoding]];
    [request setHTTPMethod:@"POST"]; //GET
    [request addValue:@"Value_to_be_added" forHTTPHeaderField:@"SOAPAction"];
    [request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation,id responseObject{

        NSLog(@"Success : Content : %@",[operation responseString]);
    } failure:^(AFHTTPRequestOperation *operation,NSError *error) {

        NSLog(@"Failed");
    })];

    [operation start];
}
