Thinkphp 在api开发中异常返回依然是html的解决方式
现在谁不开发接口的呢？但是在接口开发过程中，报错误异常后居然返回错误的信息依然是html信息！TP官方也不知道为啥不添加，说好的为接口而生，我的解决方案也很简单，把系统的异常处理类复制出来，去掉模板相关，直接以json方式输出
下面是解决方案：
1:按照TP扩展异常的方式引用这个文件
https://www.kancloud.cn/manual/thinkphp5_1/354092
// 判断默认输出类型
// $app 是配置数组
if ($app['default_return_type'] == 'json') {
// 异常处理handle类 留空使用 \think\exception\Handle
$app['exception_handle'] = '\\app\\common\\exception\\JsonException';
}
return $app;
异常处理类：
<?php
