Unable to extract image file uploaded on React frontend on Flask backend

问题 I'm trying to send an image file(that resides locally) from my react single page frontend app to my flask backend. Some of the things I have tried out but not limited to are capturing my content type and indicating the encType on the front end. Although, the post requests indicates that it was successful. However, when I log the requests.files, request.form, request.values, I get no data input. Obviously, there's something I'm missing out and could really use any help I could get from anyone.

Until today I though only InternetExplorers (<8) would show that behavior. Am I wrong here? Can somebody confirm that Chrome does not fully support ajax readystate 3 ? 回答1: After doing a lot of research and reading in webkits developer forum, I finally can tell what is happening and how to prevent that in chrome / webkit / safari
