Aws :: S3 :: Errors :: InvalidArgument：在bucket.put_object上

如何解决Aws :: S3 :: Errors :: InvalidArgument：在bucket.put_object上

我正在尝试将base64编码的图像上传到S3存储桶。登录后，我的存储桶列表可以正确显示。我正在尝试使用bucket＃put_object

上传

关于无效参数是什么，我看不到任何提示。

我的JSON正文看起来像.. ““产品”：{ “ product_photo”：“ data：image / png; base64，iVBORw0KGgoAAAANSUhEUgAAAT8AAADQCAYAAABxw2ZIAAABQGlDQ1BJQ0MgUHJvZmlsZQAAKJFjYGASSCwoyGFhYGDIGszCQJAQJAQAQJAQJAQJAQJAQJAQJAQA

如果我使用Carrierwave文件存储，则图像可以很好地保存。

如何仅使用aws-sdk上传我的base64图像？

编辑：每个@D都启用了导线跟踪。 SM

解决方法

启用wire trace来查看发送到S3的内容和响应是什么。

,

根据 documentation，:acl 的允许选项为 private,public-read,public-read-write,authenticated-read,aws-exec-read,bucket-owner-read,bucket-owner-full-control。

因此，您必须将 public_read 更改为 public-read

obj = bucket.put_object({body: data,key: name,content_type:type,acl:"public-read"})
