我正在尝试上传一个大约1.62MB的图像到一个用烧瓶写的终点。request.files对象始终为空。我检查了以下问题,但没有成功:
这是我的服务器:
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()
我的客户:
crossorigin="anonymous">
DemoStatus 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();
},
});
}
在我看来,一切都很干净,我不知道自己错在哪里。请求对象中的“文件”属性始终为空。我还尝试了postman使用post-request,表单数据key=file,value=uploaded文件,以及头内容type=“multipart/form data”。感谢您的帮助!
