如何用IOS調用WebService(SOAP接口)

編輯:關於IOS教程

在一次項目開發過程中,用到IOS調用WebService接口,所以抽個空把這方面的內容給大家整理出來,分享給大家。

方法一:使用WSDL2ObjC工具,將接口轉成OC類。

1.在浏覽器中輸入webService接口地址(Safari不可用,我用的是Firefox),如:http://xxx.xxx.asmx, 地址後面添加上.wsdl成http://xxx.xxx.asmx.wsdl打開。

2.將頁面另存為wsdl文件,保存的時候後綴加上.wsdl,保存成如xxxxService.asmx.xml.wsdl。

3.使用WSDL2ObjC工具將wsdl文件轉成OC類。

4.將生成的OC類的全部文件導入到項目中。然後就可以調用了。現在沒有寫Demo,我就貼一部分調用代碼,以後有機會傳個Demo上來。

- (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];//接口中方法傳參數
  parm.pagenow = [NSNumber numberWithInteger:aPagenow];//接口中方法傳參數
  parm.pagesize = [NSNumber numberWithInteger:aPagesize];//接口中方法傳參數
  MURPXzshServiceSoapBindingResponse *resp = [binding HkshListUsingParameters:parm];//調用方法
   
  //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,調用的方法是HkshList。

方法二:直接通過網絡請求調用,解析XML的方法。

不說了,先上代碼:

- (void)viewDidAppear:(BOOL)animated {
   
  [super viewDidAppear:animated];
   
  //假如在這開始請求
  NSString *webServiceBodyStr = [NSString stringWithFormat:
                  @"<Jsjy_yjy xmlns=\"http://murpcn.com/murpwebservice/\">"
                  "<xxx>34192</xxx>"
                  "<pagenow>1</pagenow>"
                  "<pagesize>20</pagesize>"
                  "</Jsjy_yjy>"];//這裡是參數
  NSString *webServiceStr = [NSString stringWithFormat:
                @"<?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"
                "%@\n"
                "</soap:Body>\n"
                "</soap:Envelope>",
                webServiceBodyStr];//webService頭
   
  NSString *SOAPActionStr = [NSString stringWithFormat:@"http://xxx.com/murpwebservice/%@", @"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你給我哭");
  }
}
 //接收到數據的代理

- (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字符串然後解析
   
  //系統自帶的
  NSXMLParser *par = [[NSXMLParser alloc] initWithData:[str dataUsingEncoding:NSUTF8StringEncoding]];
  [par setDelegate:self];//設置NSXMLParser對象的解析方法代理
  [par parse];//調用代理解析NSXMLParser對象,看解析是否成功
}
//解析XML

#pragma mark xmlparser
//step 1 :准備解析
- (void)parserDidStartDocument:(NSXMLParser *)parser{
   
   
}
//step 2:准備解析節點
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
  NSLog(@"%@", NSStringFromSelector(_cmd) );
}
//step 3:獲取首尾節點間內容
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
  NSLog(@"%@", string);
}
 
//step 4 :解析完當前節點
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
  NSLog(@"%@",NSStringFromSelector(_cmd) );
}
 
//step 5;解析結束
- (void)parserDidEndDocument:(NSXMLParser *)parser{
   
}
//獲取cdata塊數據
- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock{
   
}

以上內容就是用IOS調用WebService(SOAP接口)的方式,希望對大家有所啟迪。
