我正在尝试一起使用Shrine和fineuploader将我的文件直接上传到S3。
我面临的问题是Shrine gem的presign_endpoint是一个GET请求,它返回一个格式如下的json响应:
{
"url": "https://my-bucket.s3-eu-west-1.amazonaws.com",
"fields": {
"key": "b7d575850ba61b44c8a9ff889dfdb14d88cdc25f8dd121004c8",
"policy": "eyJleHBpcmF0aW9uIjoiMjAxNS0QwMToxMToyOVoiLCJjb25kaXRpb25zIjpbeyJidWNrZXQiOiJzaHJpbmUtdGVzdGluZyJ9LHsia2V5IjoiYjdkNTc1ODUwYmE2MWI0NGU3Y2M4YTliZmY4OGU5ZGZkYjE2NTQ0ZDk4OGNkYzI1ZjhkZDEyMTAwNGM4In0seyJ4LWFtei1jcmVkZW50aWFsIjoiQUtJQUlKRjU1VE1aWlk0NVVUNlEvMjAxNTEwMjQvZXUtd2VzdC0xL3MzL2F3czRfcmVxdWVzdCJ9LHsieC1hbXotYWxnb3JpdGhtIjoiQVdTNC1ITUFDLVNIQTI1NiJ9LHsieC1hbXotZGF0ZSI6IjIwMTUxMDI0VDAwMTEyOVoifV19",
"x-amz-credential": "AKIAIJF55TMZYT6Q/20151024/eu-west-1/s3/aws4_request",
"x-amz-algorithm": "AWS4-HMAC-SHA256",
"x-amz-date": "20151024T001129Z",
"x-amz-signature": "c1eb634f83f96b69bd675f535b3ff15ae184b102fcba51e4db5f4959b4ae26f4"
},
"headers": {}
}
Fineuploader使用签名端点执行POST请求,因此返回“不允许的方法”错误。
var uploader = new qq.s3.FineUploader({
request: {
endpoint: '{ CDN_ENDPOINT_URL }'
accessKey: '{ ACCESS_KEY }'
},
objectProperties: {
bucket: '{ BUCKET_NAME }'
host: '{ BUCKET_HOST_NAME }'
},
signature: {
endpoint: '/presign'
}
});
有没有办法将fineuploader的签名方法更改为GET方法,还是我完全朝错误的方向?欢迎任何有关创建此功能的建议。
我想做一些与https://github.com/gorails-screencasts/shrine-direct-upload-to-s3/blob/master/app/assets/javascripts/uploads.js类似的事情,但需要使用精细上传器。
