uber api乘车请求得到401个非自动化错误响应

Question

我正在尝试为UBER.I构建mac应用程序，我已经完成了Aouth2的所有步骤。我成功地获得了access_token。我也可以检索用户的个人资料和历史，但当我试图发布“乘坐请求”，我得到401个未经授权的错误response.please help.Thank你提前。我的代码如下。

**

//POST /v1/requests
    NSString *sandBoxURL=@"https://sandbox-api.uber.com/v1";
    NSString *url = [NSString stringWithFormat:@"%@/requests", sandBoxURL];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
    [request addValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue:[NSString stringWithFormat:@"Bearer %@", _accessToken] forHTTPHeaderField:@"Authorization"];

    NSError *error = nil;
    request.HTTPMethod = @"POST";
    request.HTTPBody = [NSJSONSerialization dataWithJSONObject:params options:0 error:&error];
    NSLog(@"Request for Product Request:%@",request);
    [self performNetworkOperationWithRequest:request completionHandler:^(NSDictionary *requestDictionary, NSURLResponse *response, NSError *error)
     {
         NSLog(@"Response for Product Request:%@",response);
         NSLog(@"Result:%@",requestDictionary);
         NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
         if (httpResponse.statusCode >= 200 && httpResponse.statusCode < 300)
         { //OK
             UberRequest *requestResult = [[UberRequest alloc] initWithDictionary:requestDictionary];
             // handler(requestResult, response, error);
         }
         if (409 == httpResponse.statusCode) { //needs surge confirmation
             NSLog(@"Surge Conflict");
         }
         else
         {
            NSLog(@"Error In response");

         }
     }];

**我得到的回应是：

    { URL: https://sandbox-api.uber.com/v1/requests } { status code: 401, headers {
    Connection = "keep-alive";
    "Content-Length" = 83;
    "Content-Type" = "application/json";
    Date = "Mon, 07 Nov 2016 11:19:35 GMT";
    Server = nginx;
    "Strict-Transport-Security" = "max-age=0";
    "X-Content-Type-Options" = nosniff;
    "X-Uber-App" = "uberex-sandbox, migrator-uberex-sandbox-optimus";
    "X-Uber-Missing-Scopes" = true;
    "X-XSS-Protection" = "1; mode=block";
} }
Result:{
    code = unauthorized;
    message = "Requires at least one scope. Available scopes: ";
}

我找到解决办法了。问题是我的作用域input.While请求令牌，即使您登录的帐户是开发人员的，我们也需要正确地放置作用域。在我的例子中，我需要请求范围来标记。
