iOS開發之iPhone通過get和post方式請求asp.net webservice

這篇文章，我將通過一個簡單的例子來展現iPhone通過get和post方式請求asp.net webservice。

webservice

1、建立一個webservice

2、在webconfig中啟用http get 和http post。

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

iphone用戶端調用：

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];
    }複製代碼

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];    }
