从浏览器直接将字符串上传到s3，而无需本地文件 [英] direct upload string from browser to s3 without local file

问题描述

我正在使用javascript，node.js和aws sdk.有很多关于使用签名URL直接将现有文件上传到S3的示例，但是现在我尝试上传字符串并在S3中创建文件，而没有任何本地保存的文件.有什么建议吗?

I am using javascript, node.js and aws sdk. There are many examples about uploading existing files to S3 directly with signed URL, but now I am trying to upload strings and create a file in S3, without any local saved files. Any suggestion, please?

推荐答案

尚未尝试 amazon-web-services ， amazon-s3 或 aws-sdk，尽管如果您能够上传 File 或 FormData 对象，则可以在JavaScript上创建一个或两个对象，然后上传对象.

Have not tried amazon-web-services, amazon-s3 or aws-sdk, though if you are able to upload File or FormData objects you can create either or both at JavaScript and upload the object.

// create a `File` object
const file = new File(["abc"], "file.txt", {type:"text/plain"});
// create a `Blob` object
// will be converted to a `File` object when passed to `FormData`
const blob = new Blob(["abc"], {type:"text/plain"});    
const fd = new FormData();
fd.append("file", blob, "file.txt");
