NSString \*action = @"getAllSubwayStationsByLine";  
int line = 1;  
NSURL \*url = \[NSURL URLWithString: @"http://192.168.1.18:8080/MobileServer/MobileWebService?wsdl"\];  
NSString \*body = \[NSString stringWithFormat: @"  
<soapenv:Envelope xmlns:soapenv=\\"http://schemas.xmlsoap.org/soap/envelope/\\" xmlns:wsc=\\"wsclient.fg114.com\\">  
<soapenv:Header/>  
<soapenv:Body>  
<wsc:getAllSubwayStationsByLine>  
<line>%d</line>  
</wsc:getAllSubwayStationsByLine>  
</soapenv:Body>

NSMutableRequest \*req = \[self requestWithURL: url\];  
\[req setHTTPMethod: @"POST"\];  
\[req setHTTPBody: \[body dataUsingEncoding: NSUTF8StringEncoding\]\];  
\[req addValue: \[NSString stringWithFormat: @"\\"%@\\"", action\] forHTTPHeaderField: @"SOAPAction"\];  
\[req addValue: @"text/xml; charset=utf-8" forHTTPHeaderField: @"Content-Type"\];

这篇博客写得也不错，可以参考

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 >

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];
        }
