html - 发送数据到网站

Question

我有一个问题。我从程序(xcode，我在 Objective C 上开发)向服务器发送一个 POST 请求，数据已发送，但我需要在网站上注册(身份验证)并且我不知道我是如何发送这个字符串的

NSString * param = [NSString stringWithFormat:@"action=login&name=%@&password=%@", myName, myPassword]

我的完整代码:

request.HTTPMethod = @"POST";

NSString * myName = _loginLogin.text;
NSString * myPassword= _passwordLogin.text;

NSString * param = [NSString stringWithFormat:@"action=login&name=%@&password=%@", myName, myPassword];
request.HTTPBody = [param dataUsingEncoding:NSUTF8StringEncoding];

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

我使用这个*(www.dnevnik.ru)*页面。

对于我的网站字符串 NSString *postString = [NSString stringWithFormat:@"&username=%@&password=%@", username, password]; 不适合？

使用以下代码: 只需添加

@property (nonatomic, strong) NSMutableData *responseData;

在您的.h文件中

NSUserDefaults *loginData = [NSUserDefaults standardUserDefaults];
    NSString *username = [loginData objectForKey:@"username"] ;
    NSString *password = [loginData objectForKey:@"password"];

    NSString *postString = [NSString stringWithFormat:@"&username=%@&password=%@", username, password];
    NSString *urlString = @"http://YourUrl";
    NSURL *myURL = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSMutableURLRequest *detailRequestToServer =[NSMutableURLRequest requestWithURL:myURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0];
    [detailRequestToServer setHTTPMethod:@"POST"];
    [detailRequestToServer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    const char *utfString = [postString UTF8String];
    NSString *utfStringLenString = [NSString stringWithFormat:@"%zu", strlen(utfString)];
    [detailRequestToServer setHTTPBody:[NSData dataWithBytes: utfString length:strlen(utfString)]];
    [detailRequestToServer setValue:utfStringLenString forHTTPHeaderField:@"Content-Length"];

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:detailRequestToServer delegate:self];
    if (theConnection)
    {
        self.responseData = [[NSMutableData alloc] init];
    }
    else
        NSLog(@"Connection Failed!");
