JSONDECODEError: Erwartungswert: Zeile 1 Spalte 1 (char 0) ⇐ Python

[Anonymous]

Ich erhalte einen Fehler, der den Wert erwartet: Zeile 1 Spalte 1 (char 0) Beim Versuch, JSON zu dekodieren. Im Folgenden ist der Code, den ich für die Curl -Anforderung verwende.

Code: Select all

response_json = self.web_fetch(url)
response_json = response_json.decode('utf-8')
return json.loads(response_json)

def web_fetch(self, url):
buffer = StringIO()
curl = pycurl.Curl()
curl.setopt(curl.URL, url)
curl.setopt(curl.TIMEOUT, self.timeout)
curl.setopt(curl.WRITEFUNCTION, buffer.write)
curl.perform()
curl.close()
response = buffer.getvalue().strip()
return response
