iOS开发之iPhone通过get和post方式请求asp.net webservice

这篇文章，我将通过一个简单的例子来展现iPhone通过get和post方式请求asp.net webservice。

webservice

1、创建一个webservice

2、在webconfig中启用http get 和http post。

         < webServices >
             < protocols >
                 < add  name ="HttpSoap" />
                 < add  name ="HttpPost" />
                 < add  name ="HttpGet" />
                 < add  name ="Documentation" />
             </ protocols >
         </ webServices >

iphone客户端调用：

1、get的方式：

NSString  * queryString  =
          [NSString stringWithFormat:
    @“http: // 10.5.23.117:5111/Service1.asmx/HelloWorld?param=123%@“,
    ipAddress.text];
    NSURL  * url  =  [NSURL URLWithString:queryString];
    NSMutableURLRequest  * req  =  [NSMutableURLRequest requestWithURL:url];
    [req addValue:@“text / xml; charset = utf - 8 ” forHTTPHeaderField:@“Content - Type”];
    [req addValue:  forHTTPHeaderField:@“Content - Length”];
    [req setHTTPMethod:@“GET”];
    [activityIndicator startAnimating];
    conn  =  [[NSURLConnection alloc] initWithRequest:req  delegate :self];
     if  (conn) {
        webData  =  [[NSMutableData data] retain];
    }

2、post的方式：

< class="brush:objc;gutter:false;">NSString *postString =@"123"; NSURL *url = [NSURL URLWithString: @“http://10.5.23.117:5111/Service1.asmx/HelloWorld2”]; NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@“%d”, [postString length]]; [req addValue:@“application/x-www-form-urlencoded” forHTTPHeaderField:@“Content-Type”]; [req addValue:msgLength forHTTPHeaderField:@“Content-Length”]; [req setHTTPMethod:@“POST”]; [req setHTTPBody: [postString dataUsingEncoding:NSUTF8StringEncoding]]; [activityIndicator startAnimating]; conn = [[NSURLConnection alloc] initWithRequest:req delegate:self]; if (conn) { webData = [[NSMutableData data] retain]; }
