[英]Flask server with threading gives “error: [Errno 32] Broken pipe”
I have enabled threaded
in the Flask dev server but it seems that it doesn't fix the "Broken pipe" error described in Flask broken pipe with requests . 我已在Flask开发服务器中启用了
threaded
,但似乎无法解决带有请求的Flask中断管道中描述的“中断管道”错误。
from flask import Flask, request
import requests
app = Flask(__name__)
@app.route('/compare', methods=['POST'])
def compare():
data = request.get_json()
img = data['img']
imgdata = requests.get(img).content # Error is from here
filename = 'hello.jpg'
with open(filename, 'wb') as f:
f.write(imgdata)
return 'Yes'
if __name__ == '__main__':
app.run(threaded=True, host='0.0.0.0', port=80)
Traceback (most recent call last):

error: [Errno 32] Broken pipe
It may be because the connection is being prematurely closed or the file is too large. 可能是因为连接过早关闭或文件太大。 Try this:
尝试这个:
import requests, shutil
from requests.exceptions import ReadTimeout, ConnectionError
img_url = data['img']
filename = 'hello.jpg'
try:
response = requests.get(img_url, stream=True)
with open(filename, 'wb') as img_file:
shutil.copyfileobj(response.raw, img_file)
except ReadTimeout:
print("Connection timeout")
except ConnectionError:
print("Connection refused")
