egg.js 24.16错误和异常统一处理

module.exports = ()=>{
    return async function errorHandle(ctx,next){
        try{
            await next();
        }catch(error){
            // 错误日志
            ctx.app.emit('error',err,ctx);
            
            ctx.status = error.status;
            ctx.body={
                msg:'fail',
                data:error.mssage
            }
        }
        return next();
    }
}

// add your middleware config here 'errorHandle'
  config.middleware = ['errorHandle'];

async create() {
    this.ctx.throw(500,'故意出错');
}
