解决方案：settings.py中加入 ：SESSION_SERIALIZER = 'django.contrib.sessions.serializers.PickleSerializer'

事由：Django去访问一个web api接口，两次连接之间需要通过Session()保持身份验证。

        
def sendCode(request): 
    mobile =json.loads(request.body).get("Mobile")
    http = requests.Session()
    result = http.get(f'http://127.0.0.1:8000/api/login?mobile={mobile}&func=send_code')
    request.session['http'] = http
    request.session['httpMobile'] = mobile
    return result

def verifyCode(request): 
    code =json.loads(request.body).get("code")
    mobile = request.session.get('httpMobile')
    http = request.session.get('http')
    result = http.get(f'http://127.0.0.1:8000/api/login?mobile={mobile}&func=verify_code&code={code}')
    return result

提示：Object of type Session is not JSON serializable

加入SESSION_SERIALIZER = 'django.contrib.sessions.serializers.PickleSerializer' 后解决。
