iphone之通过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。

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

iphone客户端调用：

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：

view sourceprint?

NSString*postString =@"123";

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>NSURL*url = [NSURLURLWithString:

<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 = [NSMutableURLRequestrequestWithURL:url];

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>NSString*msgLength = [NSStringstringWithFormat:@“%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 = [[NSURLConnectionalloc] 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 = [[NSMutableDatadata] retain];

<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>}
