iphone客戶端調用：

1、get的方式：

NSString<wbr></wbr> * queryString<wbr></wbr> =
<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>[NSString<wbr>stringWithFormat:<br><wbr><wbr><wbr><wbr>@“http:</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr> // 10.5.23.117:5111/Service1.asmx/HelloWorld?param=123%@“,
<wbr><wbr><wbr><wbr>ipAddress.text];<br><wbr><wbr><wbr><wbr>NSURL<wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr> * url<wbr></wbr> = <wbr>[NSURL<wbr>URLWithString:queryString];<br><wbr><wbr><wbr><wbr>NSMutableURLRequest<wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr> * req<wbr></wbr> = <wbr>[NSMutableURLRequest<wbr>requestWithURL:url];<br><wbr><wbr><wbr><wbr>[req<wbr>addValue:@“text</wbr></wbr></wbr></wbr></wbr></wbr></wbr> / xml;<wbr>charset</wbr> = utf - 8 ”<wbr>forHTTPHeaderField:@“Content</wbr> - Type”];
<wbr><wbr><wbr><wbr>[req<wbr>addValue:</wbr></wbr></wbr></wbr></wbr> 0 <wbr>forHTTPHeaderField:@“Content</wbr> - Length”];
<wbr><wbr><wbr><wbr>[req<wbr>setHTTPMethod:@“GET”];<br><wbr><wbr><wbr><wbr>[activityIndicator<wbr>startAnimating];<br><wbr><wbr><wbr><wbr>conn<wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr> = <wbr>[[NSURLConnection<wbr>alloc]<wbr>initWithRequest:req<wbr></wbr></wbr></wbr></wbr> delegate :self];
<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr> if <wbr>(conn)<wbr>{<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>webData<wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr> = <wbr>[[NSMutableData<wbr>data]<wbr>retain];<br><wbr><wbr><wbr><wbr>}</wbr></wbr></wbr></wbr></wbr></wbr></wbr>

2、post的方式：

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