iOS开发之iPhone通过get和post方式请求asp.net web service（转）

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" />
            
         复制代码

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: 0 forHTTPHeaderField:@“Content - Length”];
    [req setHTTPMethod:@“GET”];
    [activityIndicator startAnimating];
    conn  = [[NSURLConnection alloc] initWithRequest:req  delegate :self];
     if (conn) {
        webData  = [[NSMutableData data] retain];
    } 复制代码

2、post的方式：

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];}
