Question

我必须在iOS中访问Rest api，我正在使用RestKit。服务器只接受POST请求并以JSON发送响应。只是帮我用RestKit调用登录api。网址如下：

http://mobile.domian.co/apiversion/user/login

和帖子参数：

APP_KEY（字符串），签名（字符串），时间戳（日期时间），USER_ID（字符串），密码（字符串）。

可用的回复表示

{
"status": "0",
"result": {
    "error_code": "1",
    "error_msg": "Login failed. Wrong username or password"
}

{ “状态”：“1”， “结果”：{ “数据”：{ “avatar”：“”， “email”：“sd.p@clozette.co”， “user_name”：“sd”， “时事通讯”：“1”， “bio_data”：“关于我自己”， “mth_dob”：“1”， “yr_dob”：“1981”， “故乡”：“”， “dob_priv”：“1”， “hometown_priv”：“1”， “bio_data_priv”：“1”， “block_comment_notification”：” 0” ， “block_liked_notification”：” 0” ， }

请帮帮我。提前谢谢。

这是答案（您应该将日期时间转换为字符串）： -

        NSString *post =[NSString stringWithFormat:@"app_key=%@&signature=%@&timestamp=%@&user_id=%@&password=%@",appKEY,Signature,Datetime,UID,Password];

    NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

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

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:@"Your URL"]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSError *error;
    NSURLResponse *response;
    NSData *returnData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    if (error)
{
    NSLog(@"Error is %@",[error localizedDescription]);
}

    returnString=[[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding];
    if(!returnString)
    {
        UIAlertView *erroralert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"There is an error getting response" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        [erroralert show];
        [erroralert release];
    }
    else 
    {
        NSLog(@"%@",returnString);
    }
    SBJSON *json = [[SBJSON new] autorelease];
    NSMutableDictionary *dic = [[NSMutableDictionary alloc] initWithDictionary:[json objectWithString:returnString error:nil]];
