如何在 AWS S3 上上传多个文件并使用 Angular 将 url 存储到 Firebase?
How to upload multiple files on AWS S3 and storing the url to Firebase using Angular?
我使用 AWS S3 作为托管(文件)并使用 firebase 作为数据库,它可以正常上传单个文件吗?
有什么方法可以通过 Angular 在 S3 上上传多张图片吗?
您可以通过 AWS S3 Cognito 执行此操作 link 此处尝试此操作:
http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/browser-examples.html#Amazon_S3
也试试这个代码
只需更改区域、IdentityPoolId 和您的存储桶名称
<!DOCTYPE html>
<html>
<head>
<title>AWS S3 File Upload</title>
<script src="https://sdk.amazonaws.com/js/aws-sdk-2.1.12.min.js"></script>
</head>
<body>
<input type="file" id="file-chooser" />
<button id="upload-button">Upload to S3</button>
<div id="results"></div>
<script type="text/javascript">
AWS.config.region = 'your-region'; // 1. Enter your region
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
IdentityPoolId: 'your-IdentityPoolId' // 2. Enter your identity pool
});
AWS.config.credentials.get(function(err) {
if (err) alert(err);
console.log(AWS.config.credentials);
});
var bucketName = 'your-bucket'; // Enter your bucket name
var bucket = new AWS.S3({
params: {
Bucket: bucketName
}
});
var fileChooser = document.getElementById('file-chooser');
var button = document.getElementById('upload-button');
var results = document.getElementById('results');
button.addEventListener('click', function() {
var file = fileChooser.files[0];
if (file) {
results.innerHTML = '';
var objKey = 'testing/' + file.name;
var params = {
Key: objKey,
ContentType: file.type,
Body: file,
ACL: 'public-read'
};
bucket.putObject(params, function(err, data) {
if (err) {
results.innerHTML = 'ERROR: ' + err;
} else {
listObjs(); // this function will list all the files which has been uploaded
//here you can also add your code to update your database(MySQL, firebase whatever you are using)
}
});
} else {
results.innerHTML = 'Nothing to upload.';
}
}, false);
function listObjs() {
var prefix = 'testing';
bucket.listObjects({
Prefix: prefix
}, function(err, data) {
if (err) {
results.innerHTML = 'ERROR: ' + err;
} else {
var objKeys = "";
data.Contents.forEach(function(obj) {
objKeys += obj.Key + "<br>";
});
results.innerHTML = objKeys;
}
});
}
</script>
</body>
</html>
希望对其他人有所帮助:)

我建议使用我们的最新产品 Firebase Storage, which is a Firebase wrapper around Google Cloud Storage 来直接从移动客户端提供安全、可恢复的上传和下载——它基本上用 Firebase 数据库集成解决方案取代了它!此后,我们还获得了慷慨的免费套餐和有竞争力的价格,以及与 S3 直接兼容的 API(通过 Google 云存储)。
