如何用IOS调用WebService（SOAP接口）

如何用IOS调用WebService（SOAP接口）

- (NSString *)skHkshListOfpagenow2:(NSInteger)aPagenow pagesize:(NSInteger)aPagesize {
   
  MURPXzshServiceSoapBinding *binding = [[MURPXzshServiceSoapBinding alloc]initWithAddress:[NSString stringWithFormat:@"%@%@", self.jjjj, XZSH_SERVICE]];//接口地址
  binding.logXMLInOut = YES;//可以直接copy
  MURPXzshService_HkshList *parm = [[MURPXzshService_HkshList alloc] init];//接口中方法初始化
  parm.xxxx = [umcid stringValue];//接口中方法传参数
  parm.pagenow = [NSNumber numberWithInteger:aPagenow];//接口中方法传参数
  parm.pagesize = [NSNumber numberWithInteger:aPagesize];//接口中方法传参数
  MURPXzshServiceSoapBindingResponse *resp = [binding HkshListUsingParameters:parm];//调用方法
   
  //下面是返回值
  for (id mine in resp.bodyParts) {
   
    if ([mine isKindOfClass:[MURPXzshService_HkshListResponse class]]) {
       
      NSString *resultStr = [mine HkshListResult];
       
      return resultStr;
    }
  }
  return nil;
}

注意：上面我的webService名字是MURPXzshService，Soap是MURPXzshServiceSoapBinding，调用的方法是HkshList。
方法二：直接通过网络请求调用，解析XML的方法。
不说了，先上代码：

- (void)viewDidAppear:(BOOL)animated {
   
  [super viewDidAppear:animated];
   
  //假如在这开始请求
  NSString *webServiceBodyStr = [NSString stringWithFormat:
                  @"<Jsjy_yjy 
                  "<xxx>34192</xxx>"
                  "<pagenow>1</pagenow>"
                  "<pagesize>20</pagesize>"
                  "</Jsjy_yjy>"];//这里是参数
  NSString *webServiceStr = [NSString stringWithFormat:
                @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                "<soap:Envelope   xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                "<soap:Body>\n"
                "%@\n"
                "</soap:Body>\n"
                "</soap:Envelope>",
                webServiceBodyStr];//webService头
   
  NSString *SOAPActionStr = [NSString  @"Jsjy_yjy"];//SOAPAction
   
  NSURL *url = [NSURL URLWithString:@"http://xxxx/key/MurpjsjyService.asmx"];
  NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
  NSString *msgLength = [NSString stringWithFormat:@"%ld", webServiceStr.length];
  [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-type"];
  [theRequest addValue:SOAPActionStr forHTTPHeaderField:@"SOAPAction"];
  [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
  [theRequest setHTTPMethod:@"POST"];
  [theRequest setHTTPBody:[webServiceStr dataUsingEncoding:NSUTF8StringEncoding]];
  NSURLConnection *theConn = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
  if (theConn) {
     
    NSLog(@"8888哈哈哈笑");
  }else {
    NSLog(@"5555你给我哭");
  }
}
 //接收到数据的代理

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
   
   
}
 
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
   
  NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
  NSLog(@"%@", str);//得到想要的XML字符串然后解析
   
  //系统自带的
  NSXMLParser *par = [[NSXMLParser alloc] initWithData:[str dataUsingEncoding:NSUTF8StringEncoding]];
  [par setDelegate:self];//设置NSXMLParser对象的解析方法代理
  [par parse];//调用代理解析NSXMLParser对象，看解析是否成功
}
//解析XML

#pragma mark xmlparser
//step 1 :准备解析
- (void)parserDidStartDocument:(NSXMLParser *)parser{
   
   
}
//step 2：准备解析节点
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
  NSLog(@"%@", NSStringFromSelector(_cmd) );
}
//step 3:获取首尾节点间内容
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
  NSLog(@"%@", string);
}
 
//step 4 ：解析完当前节点
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
  NSLog(@"%@",NSStringFromSelector(_cmd) );
}
 
//step 5；解析结束
- (void)parserDidEndDocument:(NSXMLParser *)parser{
   
}
//获取cdata块数据
- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock{
   
}

以上内容就是用IOS调用WebService（SOAP接口）的方式，希望对大家有所启迪。
