    使用express框架封装restful接口，post请求跟响应都使用json格式，使用了body-parser模块
    var app = express();
    app.use(bodyParser.json());

    只要json格式一有错，发起请求后把出错信息都返回来了
    如何让异常只显示在服务端console里，而不显示到前端？
  • JSON
  • 前端
  • express

    加一个错误处理的中间件在body-parser module 后面试试。
    app.use(function (err, req, res, next) {
    //error handler
    })

    @neone app.js里面有处理错误的语句。
    if(app.get('env') === 'development')

    )

    通过环境变量来判断是否输出详细的信息。

    app.set('env', 'production');
    即可。
