我正在嘗試上傳一個大約1.62MB的圖像到一個用燒瓶寫的終點。request.files對象始終為空。我檢查了以下問題,但沒有成功:

這是我的服務器:

from flask import Flask, request, jsonify, render_template

import sys

app = Flask(__name__)

app.config['UPLOAD_FOLDER'] = r"C:\Temp"

app.debug = True

@app.route("/demo-upload", methods=["GET", "POST"])

def ProcessImage():

if request.method == "POST":

print(request.files)

try:

if 'file' in request.files:

with open("test-upload.png", "wb") as iFile:

print(request['file'])

iFile.write(request.files['file'])

except Exception as e:

print(e)

return jsonify("Ok")

@app.route("/", methods=["GET"])

def DemoIndexPage():

return render_template("index.html")

if __name__ == "__main__":

app.run()

我的客戶:

crossorigin="anonymous">

Demo

Status Demo

upload image to process.

Success!

function ProcessImage()

{

var form_data = new FormData($('#File')[0]);

console.log(form_data)

$.ajax({

type: 'POST',

url: '/demo-upload',

data: form_data,

contentType: false,

cache: false,

processData: false,

async: false,

success: function (data) {

console.log('Success!');

$("#status").show();

},

});

}

在我看來,一切都很干凈,我不知道自己錯在哪里。請求對象中的“文件”屬性始終為空。我還嘗試了postman使用post-request,表單數據key=file,value=uploaded文件,以及頭內容type=“multipart/form data”。感謝您的幫助!
