回形针::错误:: NotIdentifiedByImageMagickError-Rails应用程序+ 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。

我在用：

• 亚马逊EC2
• Ruby on Rails
• 回形针

我正在执行以下代码：

迅速

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

然后我通过一个参数发送信息：

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)"

请注意，我的标题是：

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

现在正在工作。 解决方案是：

我只是将aws-sdk gem的版本从<2更改为gem 'aws-sdk', '>= 2.0.0' ，效果很好。

除此之外，我还在Amazon EC2和Rmagick上重新安装了imagemagick。
