Paperclip::Errors::NotIdentifiedByImageMagickError - Rails 应用 + Swift 2

Question

我正在尝试从 Swift 2 应用程序上传照片，但收到错误请求。

我正在使用：

亚马逊 EC2
Ruby 在 Rails
回形针

我正在执行这段代码：

Swift

func convertImageToBase64(image: UIImage) -> String {
   let imageData = UIImagePNGRepresentation(image)
   let base64Encoded = imageData!.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)
   return base64Encoded
}

然后我通过参数发送信息：

let image_str = self.global.convertImageToBase64(self.global.compressForUpload(self.newMediaImage.image!, withHeightLimit:750, andWidthLimit:750))

parameters["spot[image]"] = "data:image/png;base64,\(image_str)"

注意我的 headers 是：

headers["Accept"] = "application/json"
headers["Content-Type"] = "multipart/form-data"
headers["Access-Control-Request-Method"] = "POST"
headers["Access-Control-Request-Headers"] = "X-Requested-With"

我收到此消息错误：

Answer 1

现在可以了。解决方案是：

我刚刚将 aws-sdk gem 的版本更改为 < 2 gem 'aws-sdk', '>= 2.0.0' 效果很好。

除此之外，我 re-installed imagem在 amazon ec2 和 Rmagick 上使用 agick。
