通过NG-文件上传上传到Amazon S3;错误400 [英] Uploading to Amazon S3 via ng-file-upload; Error 400
问题描述
我使用 NG-文件上传以将照片上传到S3。我测试了我的S3桶，并与NG-文件上传我的政策/签名生成演示工具并已成功用它的照片上传到我的桶中。
的编辑：的一个关键的区别似乎是增加了一个头的：
授权：令牌3j4fl8jk0lqfkj4izj2w3ljfopljlwep1010notreal
这是在我的code present但不是在演示页。也许是我的角度应用程序。
通过安装鲍尔，采取了相关的组件，试图上传文件，并得到看起来像这样的错误：
400？＆LT; XML版本=1.0编码=UTF-8＆GT;？
＆LT;错误＆GT;
＆LT; code基InvalidArgument＆LT; / code＆GT;
＆LT;消息＆GT;不支持的授权类型＆lt; /信息＆GT;
＆LT; ArgumentName＆GT;授权＆LT; / ArgumentName＆GT;
＆LT; ArgumentValue＆GT;令牌3j4fl8jk0lqfkj4izj2w3ljfopljlwep1010notreal＆LT; / ArgumentValue＆GT;
＆LT;＆的requestId GT; F1F5FK - 不实81FED9CA＆LT; /＆的requestId GT;

＆LT; /错误＆GT;
搜索周围，我注意到很多400错误，但与 ArgumentValue 为令牌[some- code-这里就不多的情况下] 。
看着 AWS文档， InvalidArgument 是有人相当新的AWS有点不透明。
这是我在编码策略（蟒蛇）：
#exptime ='2100-07-31T06：23：35Z#for调试
policy_document = {过期：exptime，
条件： [
{桶：settings.AWS_STORAGE_BUCKET_NAME}，
[开始，以'$钥匙，]，
{以acl：私有}，
[开始-带，$内容类型，]，
[开始-带，$文件名，]，
[内容长度范围，0，5000000]
]
}
要重申，这一政策与上述演示工作，所以我希望在我的前端设计了一个问题：
$ scope.upload =功能（文件）{
file.upload = Upload.upload（{
网址：'https://mybucket.s3-us-west-2.amazonaws.com'，
方法：POST，
字段：{
键：file.name，
AWSAccessKeyId：myAccessKeyId，
ACL：私人，
政策：myPolicyEn codeD，
签名：mySignatureEn codeD，
内容类型：file.type ===空||
file.type ==='？ 应用程序/八位字节流：file.type，
文件名：file.name
}，
文件：文件
}）;
}
我花了一段时间才能找到它，但我的编辑指出，展望请求头中的角应用程序的登录/ AUTH过程中使用的令牌是发送作为默认，和亚马逊的服务不喜欢这一点。删除页眉在这种特殊情况下的http请求解决问题。
在我的前端上传服务这样的样子：
$ scope.upload =功能（文件）{
file.upload = Upload.upload（{
网址：'https://mybucket.s3-us-west-2.amazonaws.com'，
方法：POST，
字段：{
键：file.name，
AWSAccessKeyId：myAccessKeyId，
ACL：私人，
政策：myPolicyEn codeD，
签名：mySignatureEn codeD，
内容类型：file.type ===空||
file.type ==='？ 应用程序/八位字节流：file.type，
文件名：file.name
}，
标题：{
'授权'：未定义
}，
文件：文件
}）;
}
I am using ng-file-upload to upload a photo to S3. I have tested my S3 bucket and my policy/signature generator with the ng-file-upload demo tool and have successfully used it to upload the photo to my bucket.
Edit: A key difference seems to be the addition of a header:
Authorization:Token 3j4fl8jk0lqfkj4izj2w3ljfopljlwep1010notreal
That is present in my code but not in the demo page. Perhaps it's my angular app.
Installed through bower, took the relevant components, tried to upload a file, and get an error that looks like this:
400: <?xml version="1.0" encoding="UTF-8"?>
<Error>
<Code>InvalidArgument</Code>
<Message>Unsupported Authorization Type</Message>
<ArgumentName>Authorization</ArgumentName>
<ArgumentValue>Token 3j4fl8jk0lqfkj4izj2w3ljfopljlwep1010notreal</ArgumentValue>
<RequestId>F1F5FK-not-real-81FED9CA</RequestId>
<HostId>CQEW98p3D2e+pVz-not-real-codeu28m7asqpGjagL3409gj3f4kijKJpofk</HostId>
</Error>
Searching around, I've noted many 400 Errors but not many cases with the ArgumentValue as Token [some-code-here].
Looking at AWS documentation, InvalidArgument is a bit opaque for someone rather new to AWS.
And here is the policy that I'm encoding (Python):
#exptime = '2100-07-31T06:23:35Z' #for debugging
policy_document = {"expiration": exptime,
"conditions": [
{"bucket": settings.AWS_STORAGE_BUCKET_NAME},
["starts-with", '$key', ""],
{"acl": "private"},
["starts-with", "$Content-Type", ""],
["starts-with", "$filename", ""],
["content-length-range", 0, 5000000]
]
}
To reiterate, this policy with the aforementioned demo worked, so I expect a problem on my front-end implementation:
$scope.upload = function(file) {
file.upload = Upload.upload({
url: 'https://mybucket.s3-us-west-2.amazonaws.com',
method: 'POST',
fields: {
key: file.name,
AWSAccessKeyId: myAccessKeyId,
acl: 'private',
policy: myPolicyEncoded,
signature: mySignatureEncoded,
"Content-Type": file.type === null ||
file.type === '' ? 'application/octet-stream' : file.type,
filename: file.name
},
file: file
});
}
Took me a while to find it, but as my edit pointed out, looking into the request header a token used in the Angular app's login/auth process was being sent as a default, and Amazon's service didn't like that. Removing the header in the http request for this specific case solved the issue.
The upload service on my front-end thus looks like:
$scope.upload = function(file) {
file.upload = Upload.upload({
url: 'https://mybucket.s3-us-west-2.amazonaws.com',
method: 'POST',
fields: {
key: file.name,
AWSAccessKeyId: myAccessKeyId,
acl: 'private',
policy: myPolicyEncoded,
signature: mySignatureEncoded,
"Content-Type": file.type === null ||
file.type === '' ? 'application/octet-stream' : file.type,
filename: file.name
},
headers: {
'Authorization': undefined
},
file: file
});
}
