为什么我在向 Uber Sandbox 发送请求时会收到此错误消息? NSURLErrorDomain 错误-1012

Why am I getting this error posting a request to the Uber Sandbox? NSURLErrorDomain error -1012

我可以从产品路径中获取产品 ID,但是在尝试 post 向沙盒安排乘车请求时出现此错误。试图弄清楚我在这里做错了什么。我添加了不记名令牌。我不确定它想要什么或缺少什么。

func performPostUberRequest(url: NSURL, prodId: String) {
    let params:[String: AnyObject] = [
        "start_latitude" : "39.955715",
        "start_longitude" : "-75.1680298",

        "end_longitude" : "-75.1409609",
        "product_id": prodId

    var error: NSError?
    var request: NSMutableURLRequest = NSMutableURLRequest(URL: url)
    request.HTTPMethod = "POST"
    request.addValue("Bearer \(uberToken)", forHTTPHeaderField: "Authorization")
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions.allZeros, error: &error)
    NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()){
        response, data, error in
        if let error = error {
            println(error)
        } else if data != nil {
            if let json: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as? NSDictionary {
                println(json)
            }
        }
    }
}

根据您的评论:{ code = unauthorized; message = "Missing scope: request"; },您可能错过了范围,可以在您的 Uber 开发人员仪表板上指定,您在其中注册了应用程序并获得了密码和客户端 ID 等。

如果您这样做了,您应该在开始请求 authorization codeaccess tokenOAuth2.0 时将必要的范围添加到参数中。

在我的实现中,范围指定如下:

[[NXOAuth2AccountStore sharedStore] setClientID:_clientID
                                         secret:_clientSecret
                                          scope:[NSSet setWithObjects:@"request", @"history_lite", @"profile", @"request_receipt", nil]
                               authorizationURL:[NSURL URLWithString:@"https://login.uber.com/oauth/authorize"]
                                       tokenURL:[NSURL URLWithString:@"https://login.uber.com/oauth/token"]
                                    redirectURL:[NSURL URLWithString:_redirectURL]
                                  keyChainGroup:nil
                                 forAccountType:_applicationName];
