Ios 在NSString中过帐两个键值对

我正在尝试使用

nsurlconnection

中的

post

在服务器上发布登录信息。我必须将两个键值对设置为

emailIdSignIn:abc@def.com

和

密码签名：xxxxxxx

。但问题是，我在服务器上只获得了

emailIdSignIn

值，并且

passwordSignIn

的值附加在

emailIdSignIn

字段中，

passwordSignIn

为零。我也尝试了

NSDictionary

，但在这种情况下，两个字段都得到了

null

。我无法更改服务器端代码。这是我的密码 客户端

 /* initiating request with the url */
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://192.168.1.2:8080/referamaid/app/noauth/serviceconsumer/login"]];

    NSString *loginData = [NSString stringWithFormat:@"emailIdSignIn=%@,passwordSignIn=%@",[self.emailTextField text],[self.passwordTextField text],nil];

    NSLog(@"login data = %@", loginData);


    NSData *postData = [loginData dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSError *error;

    NSString *postLength = [NSString stringWithFormat:@"%lu", [postData length]];

    /* specify the request type */

    [request setHTTPMethod:@"POST"];


    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];

    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

    /* set the data to be posted on server into body for "POST"*/

    [request setHTTPBody:postData];

    NSLog(@"posted data = %@", postData);

    /* inititate connection between app and server*/

    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];
    [connection scheduleInRunLoop:[NSRunLoop mainRunLoop]
                          forMode:NSDefaultRunLoopMode];

    [connection start];
    if(!connection)
    {
        // Release the receivedData object.

        receivedData = nil;

        // Inform the user that the connection failed.
    }
}
}

    String retVal = null;
    ObjectMapper objectMapper = new ObjectMapper();

        String emailId = request.getParameter("emailIdSignIn");
        String password = request.getParameter("passwordSignIn");

发件人：

当web浏览器从web表单元素发送POST请求时 默认Internet媒体类型为“application/x-www-form-urlencoded”。[8] 这是一种对可能重复的键值对进行编码的格式 钥匙。每个键值对由一个“&”字符分隔，每个 键与其值之间用“=”字符分隔。键和值 通过将空格替换为“+”字符，然后 对所有其他非字母数字[9]字符使用URL编码

因此，您需要使用

&

字符，而不是

，

：

NSString *loginData = [NSString stringWithFormat:@"emailIdSignIn=%@&passwordSignIn=%@",[self.emailTextField text],[self.passwordTextField text]];

NSLog（@“登录数据=%@”，登录数据）打印正确的数据？您可以显示您尝试的字典代码吗？这是登录数据=emailIdSignIn=k@k.com，passwordSignIn=12345678为什么不使用AFNetworking库，在这里您可以使用参数创建NSDictionary并将其传递给.POST方法？我使用NSDictionary保存数据，然后使用NSDictionary->JSON->POST
