AttributeError:“请求"对象没有属性"is_xhr"

问题描述

我正在尝试运行布谷鸟API.布谷鸟网络在我的系统上运行正常.但是当我尝试使用布谷鸟API时，出现以下错误:

I am trying to run cuckoo api. Cuckoo web is working fine on my system. But when I tried cuckoo api, I got the following error:

File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1982, in wsgi_app

  return getattr(self._get_current_object(), name)

AttributeError: 'Request' object has no attribute 'is_xhr'

我尝试通过添加以下代码来更改api.py:

I tried to change api.py by adding the following code:

@app.route("/publish/epoch/end/", methods=['POST'])
def publish():
    #payload = request.form.get('data')
    payload = unquote(request.data.split('=')[1]).replace('+','')
    try:
       `enter code here` data = json.loads(payload)
    except:
        return {'error':'invalid payload'}

    def notify():
        msg = str(time.time())
        for sub in subscriptions[:]:
            sub.put(payload)

    gevent.spawn(notify)
    return "OK"

@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        model.save()
        # Failure to return a redirect or render_template
    else:
        return render_template('index.html')

但这对我没有帮助.该问题的解决方案是什么?

But that didn't help me. What could be the solution to this issue?

推荐答案

从Werkzeug 0.13开始不推荐使用 request.is_xhr 属性，并在Werkzeug 1.0.0中将其删除.当使用Flask< = 0.12.4和Werkzeug> = 1.0.0时，您会收到此错误，因为Flask在1.0.0版本之前的源代码中使用此属性.您可以升级Flask(> = 1.0.0)来解决此问题:

The request.is_xhr property was deprecated since Werkzeug 0.13 and removed in Werkzeug 1.0.0. You will get this error when using Flask <= 0.12.4 and Werkzeug >=1.0.0 because Flask uses this property in the source before the 1.0.0 version. You can just upgrade Flask (>=1.0.0) to fix this issue:

$ pip install -U flask

否则，您也可以将Werkzeug降级到0.16.1:

Otherwise, you can also downgrade Werkzeug to 0.16.1:

$ pip install werkzeug==0.16.1
