multipartform-data

问题 I'm trying to upload a binary file to a Flask endpoint without using any type of multipart/form-data . I'd like to simply POST or PUT the data inside the file to the endpoint, and save it to a file on the server. The only examples I can find, and the only method discussed in other questions, uses multipart/form-data . The following "works", but the SHA256 hashes usually don't match, whereas uploading as form-data works fine. @application.route("/rupload/<filename>", methods=['POST', 'PUT'])

问题 I'm trying to use the native Fetch and FormData APIs to upload multiple files at once to the server but I can't for the life of me get it to work.

问题 Is there an equivalent to this statement in jQuery? var value = document.getElementById(id).files[0]; Using the standard jQuery selectors with .files[0] appended doesn't appear to work, and I can't find an equivalent jQuery command to .files.
