Question

我想通过Ajax调用Twilio api，获取sms日志，然后将结果打印为HTML。我无法正确解析ajax调用的响应。

python代码是：

@application.route("/custom_log", methods=['POST'])
def customlog():
    to_number = request.values.get('to_number', None)
    user_id = session.query(User.id).filter(User.validation == request.cookies.get("validation")).scalar()
    sub_account_sid = session.query(Credential.twilio_id).filter(Credential.user_id == user_id).scalar()
    sub_account_auth_token = session.query(Credential.twilio_token).filter(Credential.user_id == user_id).scalar()
    client = TwilioRestClient(sub_account_sid, sub_account_auth_token) 
    msgs = client.messages.list(to=to_number) 
    for m in msgs:  
        print m.status
    return msgs

ajax代码是：

<script>
$(document).ready(function() {
    $( "#custom_log_btn" ).click(function() {
    alert('script')
        var to_number = $('#to_number').val();
        //var date_from = $('#datepicker_from').datepicker({ dateFormat: 'yyyy-mm-dd' }).val();
        //var date_to = $('#datepicker_to').datepicker({ dateFormat: 'yyyy-mm-dd' }).val();
        $.ajax({
            url: '/custom_log',
            data: { 'to_number': to_number }, 
            type: 'POST',
            success: function(msgs) {
                alert(msgs)
                var html = '<table class="table table-striped table-hover">{% for m in msgs %}';
                    html += '<tr>';
                    html += '<td><a href="/detail?sid="{{ m.sid }}">Detail</a></td>';
                    html += '<td>{{ m.date_sent }}</td>';
                    html += '<td>{{ m.from_ }} </td>';
                    html += '<td>{{ m.to }} </td>';
                    html += '<td>{{ m.status }} </td>';
                    html += '</tr>';
                    html += '{% endfor %}</table>';
                    $("#result").html(html);

                    return false;
                //});
            },
            error: function(error) {
                console.log(error);
            }
        });
    });
});
</script>

追溯是：

我认为错误来自返回线。我已经尝试了返回'OK'，返回m.status，这也不会产生预期的结果。我希望能够将结果从Twilio api调用传递回ajax函数，以便我可以打印它。我怎样才能做到这一点？

确实，您不允许返回列表。返回json.dumps(msgs)并在javascript中将其解析为JSON.parse(response)。然后你将有一个javascript数组。

使用Python，Flask和Ajax，我如何解析ajax调用的响应并打印为HTML？
