Ios 推特API允许我通过状态发布推特，但如果我想添加图像，则不上传媒体

在登录Twitter并通过身份验证后，我能够成功地将一条推文（只是消息）发布到更新url

常数

let kTwitterPOSTmethod = "POST"
let kTwitterUpdateURL = "https://api.twitter.com/1.1/statuses/update.json"
let kTwitterUploadURL = "https://upload.twitter.com/1.1/media/upload.json"

Twitter客户端的东西

  let store = Twitter.sharedInstance().sessionStore

  if let userid = store.session()?.userID {

    let client = TWTRAPIClient(userID: userid) //from logInWithCompletion() in the previous VC

....

}

当base64Image字符串为“”时有效的函数

包含图像时不起作用的函数。我发布到上传url并尝试使用JSON序列化程序函数获取媒体id字符串，但它告诉我我未经授权

    else {

        let postImageWithStatusRequest = client.URLRequestWithMethod(kTwitterPOSTmethod, URL: kTwitterUploadURL, parameters: ["media": snapBase64String], error: nil)

        client.sendTwitterRequest(postImageWithStatusRequest, completion: { (response, data, error) in

            if error != nil {

                print(error?.localizedDescription)
            }


            if let mediaDict = self.dataToJSON(data!) {

                let message = ["status": withMessage, "media_ids": mediaDict["media_id_string"]]

                let request = client.URLRequestWithMethod(kTwitterPOSTmethod,
                    URL: kTwitterUpdateURL, parameters: message as! [String : AnyObject], error:nil)

                client.sendTwitterRequest(request, completion: { (response, data, connectionError) -> Void in

                    if connectionError == nil {
                        print("sendTwitterRequest(): \(response)")
                        complete(success: true)
                    }
                    else {
                        print("sendTwitterRequest(): \(connectionError)")
                        complete(success: false)
                    }


                })
            }
        })

    }

JSON转换函数

class func dataToJSON(data: NSData) -> AnyObject? {

    do {
        return try NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers)
    } catch let myJSONError {
        print(myJSONError)
    }
    return nil
}

我收到的错误消息。。。我是否需要不同的身份验证才能发布到服务器的上载部分？我不知道为什么它允许我发布状态，但当我想发布媒体时，它不起作用

▿ 可选的 -Some:Error Domain=TwitterAPIErrorDomain Code=32“请求失败：未经授权（401）” UserInfo={NSErrorFailingURLKey=,， NSLocalizedDescription=请求失败：未经授权（401）， NSLocalizedFailureReason=Twitter API错误：无法进行身份验证 你（代码32）}

谢谢你的帮助

我弄明白了，这与身份验证无关，这个错误很容易引起误解

我所做的是改变了我编码base64字符串的方式。我只是将选项设置为nothing，而不是64CharacterLineLength，结果成功了

let base64String = mapSnapData.base64EncodedStringWithOptions([])
snapBase64String = base64String

更新：我将参数“media”更改为“media\u data”，我认为它应该是，并且仍然得到相同的东西…更新：我将参数“media”更改为“media\u data”，我认为它应该是，并且仍然得到相同的东西。。。
