【问题描述】:
我正在学习 Polymer。我无法计算使用<iron-ajax>“发布”的代码。我正在使用在线测试 API (https://reqres.in/),我应该会收到带有状态码 200 的回复:
{"token": "QpwL5tke4Pnpja7X"}".
我找不到显示POST 示例的教程。过去 24 小时我一直在网上搜索,但所有内容都是关于 GET 而不是 POST。
如果任何熟悉 <iron-ajax> 的人都可以查看我的代码并帮助我使其工作或弄清楚如何编写正确的代码,这对像我这样的初学者非常有帮助。
- 我的代码与
body属性是否正确? -
响应是
200状态码还是令牌?<!-- @license Copyright (c) 2016 The Polymer Project Authors. All rights reserved.
