我正在尝试将视频上传到之前使用$cordovaCapture录制的亚马逊s3. 捕获过程正常工作,作为响应,我得到了对象： [MediaFile] 0: MediaFileend: 0 fullPath: "file:/storage/sdcard/DCIM/Camera/VID_20160919_144041.mp4
捕获过程正常工作,作为响应,我得到了对象：
[MediaFile]
0:
MediaFileend: 0
fullPath: "file:/storage/sdcard/DCIM/Camera/VID_20160919_144041.mp4"
lastModified: null
lastModifiedDate: 1474288843000
localURL: "cdvfile://localhost/persistent/DCIM/Camera/VID_20160919_144041.mp4"
name: "VID_20160919_144041.mp4"
size: 17098
start: 0
type: "video/mp4"
__proto__: utils.extend.F
length: 1
__proto__: Array[0]
然后,在我上传视频之前,我向服务器请求Authenticating URL,如下所示：
的NodeJS
getSignedUrl: function (filename, type, callback) {
if (filename) {
AWS.config.update({
accessKeyId: 'my_access_key',
secretAccessKey: 'my_secret_access_key',
region: 'my_region'
});
var s3 = new AWS.S3();
s3.getSignedUrl('putObject', {Bucket: 'my_bucket', Key: 'uploads/' + filename, ContentType: type}, function (err, url) {
if (err) {
callback(err);
} else {
callback(url);
}
});
} else {
callback('Error');
}
}
这给了我下一个端点：
https://s3-my_region.amazonaws.com/my_buckethttp://img.558idc.com/uploadfile/VID_20160919_144…=video%2Fmp4&Expires=1474289746&Signature=sF67ukPu3oELJXzsmAXCeeEJ%2FE4%3D
在我获得指向上传的URL之后,这里出现了问题：
有这个代码：
var options = {
httpMethod: "PUT",
fileName: name,
mimeType: type,
chunkedMode: 'false',
encodedURI: 'false',
headers: {
"Content-Type": type
}
};
$cordovaFileTransfer.upload(url, videoPath, options)
.then(function (result) {
callback(result);
}, function (err) {
callback(err);
}, function (progress) {
p = progress;
});
这是我得到的错误：
http status: 403
Code: 1

听起来问题是在标题周围,这不能按预期工作.
同样,我在我的客户端尝试了第二个选项代码,直接遵循cordova-plugin-file-transfer的文档：
var options = new FileUploadOptions(),
ft = new FileTransfer();
options.httpMethod = "PUT";
options.fileName = name;
options.mimeType = type;
options.headers = {
ContentType: type
};
options.chunkedMode = "false";
options.encodeURI = "false";
ft.upload(videoPath, url, callback, callback, options);
具有相同的响应错误.
在这里,我也遇到了Content-Type的问题.即使在文档中声明如下：
var headers = {
"Content-Type": 'video/mp4'
};
options.headers = headers;
它让我回到下一个错误：
http status: 501
description: <?xml version="1.0" encoding="UTF-8"?>
<Error>
<Code>NotImplemented</Code>
<Message>
A header you provided implies functionality that is not implemented
</Message>

<RequestId>231F38AFFBB587C6</RequestId>
.
.
.
</Error>
就像一张纸条,我用它的$http.post工作,就像我在this的其他帖子一样.
UPDATE
在这个问题上调查得更多,使用nodeJS代码我也无法上传任何东西,所以我只是这样修改了S3构造函数：
s3 = new AWS.S3({
signatureVersion: 'v4',
region: "us-west-2"
});
之后,像这样通过控制台检查curl：
curl -v -H "Content-Type: application/octet-stream" --upload-file "/Users/my_user/Desktop/VID_20160920_233443.mp4" "https://s3-us-west-2.amazonaws.com/my_buckethttp://img.558idc.com/uploadfile/VID_20160920_233443.mp4?Content-Type=video%2Fmp4&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJV3UP7LBEKPYMLGA%2F20160921%2Fus-west-2%2Fs3%2Faws4_request&X-Amz-Date=20160921T103723Z&X-Amz-Expires=600&X-Amz-Signature=8463625a45237452280b3dc9cfd89366093f7b78f8c76598ba2240f06c7f20c9&X-Amz-SignedHeaders=host%3Bx-amz-acl&x-amz-acl=public-read"

改变像这个新的角度代码：
var options = new FileUploadOptions(),
ft = new FileTransfer();
options.httpMethod = "PUT";
options.fileKey = "file";
options.fileName = name;
options.mimeType = type;
options.chunkedMode = false;
options.headers = {
"Content-Type": type,
"x-amz-acl": 'public-read'
};
ft.upload(videoPath, url, callback(null), callback, options);
问题仍然存在：

这里我包含了我的FileUploadOptions()：

从ngCordova直接尝试使用$cordovaFileTransfer插件,我收到另一个错误：
"<?xml version="1.0" encoding="UTF-8"?> <Error><Code>AuthorizationQueryParametersError</Code><Message>Error parsing the X-Amz-Credential parameter; the Credential is mal-formed; expecting "<YOUR-AKID>/YYYYMMDD/REGION/SERVICE/aws4_request".</Message><RequestId>C863350E96804F5C</RequestId><HostId>7TmXBDlsGNvDmLFKgLePTMAg+Onf8y1ZPTEWmbdHPAyWHFIdt1+5J7U3H8Ygnf3sebMRpRNdxXA=</HostId></Error>"

为了尽可能地澄清一切,我已经部署了一个github,其中包含我正在工作的所有后端/前端.
再次感谢.

感谢daserge的帮助,我可以得到我的PUT的标题.下面我粘贴结果：
HTTP/1.1 400 Bad Request x-amz-request-id 3F686CFD09B5C6DD x-amz-id-2 KDrmvzhnrWfLB+Tdttg88MaPVOp2LOBAhwEqiBR0XdMpaje3lRsiM6mHfjv5ULzD7GweiT9C2T0= Content-Type application/xml Date Sat, 24 Sep 2016 17:00:03 GMT Server AmazonS3 Transfer-Encoding chunked Proxy-Connection Close PUT /my_buckethttp://img.558idc.com/uploadfile/VID_20160924_190000.mp4?Content-Type=video%252Fmp4&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJV3UP7LBEKPYMLGA%252F20160924%252Fus-west-2%252Fs3%252Faws4_request&X-Amz-Date=20160924T170002Z&X-Amz-Expires=600&X-Amz-Signature=ca3c992290bdf51e14bab6d67e4c520b280368bdd2a0274b552dc3e975f55c9d&X-Amz-SignedHeaders=host%253Bx-amz-acl&x-amz-acl=public-read HTTP/1.1 Content-Type application/octet-stream Content-Length 56116 User-Agent Dalvik/2.1.0 (Linux; U; Android 5.0; Aquaris E5 HD Build/LRX21M) Host s3-us-west-2.amazonaws.com Connection Keep-Alive Accept-Encoding gzip
然后我意识到有2个参数错误：
Content-Type: application/xml Transfer-Encoding: chunked
同样,我已经考虑过编码.它应该是/它就像％2F一样.
这很奇怪,因为我使用params的方式似乎是正确的：
options = {
fileKey: 'file',
fileName: name,
chunkedMode: false,
httpMethod: 'PUT',
mimeType: "application/octet-stream",
headers: {
"Content-Type": "application/octet-stream"
}
};
$cordovaFileTransfer.upload(server, filePath, options)
.then(function (result) {
console.log(result);
}, function (err) {
console.log(err);
}, function (progress) {
console.log(progress);
});
同样,感谢bvakiti我已经意识到有一条错误消息,因为我正在将视频发送到https.我正在尝试http.
您从AWS获得的端点与使用$cordovaFileTransfer的方式之间似乎存在冲突.当您在服务器中使用s3.getSignedUrl获取端点时,只会对响应URL的参数进行编码(基本URL保持非编码状态).
当你使用$cordovaFileTransfer时,该函数再次对params进行编码,这就是为什么你看到％2F与//匹配的原因.
有3种选择：
>相反,在你的$cordovaFileTransfer调用之前,解码params
var host = server.split('?')[0] + '?' + decodeURIComponent(server.split('?')[1]);
>使用documentation中描述的options.params
在其他帮助评论中建议的encodeURI：false选项对我不起作用
希望能帮助到你.
