使用表单发布时出现字符错误

Question

有人遇到过这样的错误吗？当我尝试使用表单登录并检查 mysql 中的数据时，出现错误：

Request Method: POST
Request URL:    http://tesmyapp.loc/post/login/
Django Version: 1.9.7
Exception Type: OperationalError
Exception Value:    
near "????????������????????����": **syntax error**
Exception Location: /myapp/env/lib/python2.7/site-packages/django/db/backends/sqlite3/operations.py in _quote_params_for_last_executed_query, line 129
Python Executable:  /myapp/env/bin/uwsgi

我不确定这是mysql的错误，因为当我尝试在不检查数据库的情况下发布时，错误仍然出现

views.py 中的函数

@csrf_protect
def post_login(request):
    if request.method == 'POST':
        username = request.POST.get("username", "")
        password = request.POST.get("password", "")
        mylogin = check_login(username, password)
        if mylogin > 0:
            occur = "success"
            request.session['member'] = username
            return HttpResponseRedirect("/home")

如果有人遇到此错误，请分享解决方案。谢谢
