1。后台利用 cxf 构建一个web service服务。

  • HelloWorld.java

  16. @WebMethod
  17. String sayHi(String text);
  18. @WebMethod
  19. boolean userLogon(String username,String userpasswd);
  20. }
  • HelloWorldImpl.java

  38. {
  39. return true;
  40. }else{
  41. return false;
  42. }
  43. }
  44. }
  • java 的web service 访问客户端

其中要注意的几点。

  • [cpp] view plaincopy

    1. <ns1:userLogon xmlns:ns1=\"http://localhost:8080/SampleWebService/webservice/HelloWorld/\">"
    2. "<arg0>%@</arg0>"
    3. "<arg1>%@</arg1>"
    4. "</ns1:userLogon>"

    中web service 中的 userLogon方法的调用 要用ns1来引用。

  • 传递的参数 不能和 webservice的变量名来写。而只能写成 arg0 和 arg1 这种方式。我查阅其他网上资料，都是写成<username>和<userpasswd>这种element的形式。但是在我的这个演示中，如果写成这种方式。后台会无法获得传入的变量。而用arg0 这种方式是可以传入。我不清楚是否是和 java cxf的webservice搭建环境和版本有关。

注意:如果后台的WebService是.net开发的，调用的程序略有不同：

例如 后台的ws服务链接是 ：http://10.100.111.231:9000/MobileService.asmx

那么访问这个url，会返回如下内容：

这个页面提示了SOAP 1.1 和 SOAP 1.2 的调用的内容

那么，我们在objectiveC中代码应该写成

static NSString * wsURL = @"http://10.100.111.231:9000/MobileService.asmx";

NSString *soapMessage = [NSString stringWithFormat:
                             @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"

                             "<soap:Body>\n"
                             "<Logon xmlns=\"http://tempuri.org/\">"

                             "<password>%@</password>"
                             "</Logon>"
                             "</soap:Body>\n"
                             "</soap:Envelope>",self.userNameTextField.text,self.userPasswordTextField.text];
    
    NSLog(@"调用webserivce的字符串是:%@",soapMessage);
    //请求发送到的路径
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",wsURL]];
    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
    
     //以下对请求信息添加属性前四句是必有的，
    [urlRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [urlRequest addValue:@"http://tempuri.org/Logon" forHTTPHeaderField:@"SOAPAction"];
    NSLog(@"SOAPAction is %@ ",@"http://tempuri.org/Logon");
    [urlRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

//请求
    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
    theConnection = nil;

注意红色的代码，这个http://tempurl.org/Logon 是要和 .net中的代码一致。否则无法访问。
