在javascript中发送和接收blob

Question

I want to send a blob using a JQuery ajax request and receive it server-side with Node.js + express.

I would send the blob as a JSON string, but it seems that none of the binary data is included in it:

{"type":"audio/wav","size":344108}

How else could it be sent?

Answer 1

JSON doesn't support binary data. You will have to encode your binary data first: Binary Data in JSON String. Something better than Base64
