当我尝试访问/ course/new时出现错误[ReferenceError: next is not defined].
我如何以及在哪里为我的断层函数定义下一个?如果我只是next像我在早期模型中所做的那样添加一个参数,我只会得到更多错误.
courseController:
module.exports = {
'new':function(req, res, err){
Student.findOne(req.param('takes'), function foundStudent (err, student){
if (err) return next(err);
if (!student) return next();
res.view({
student: student
});
});
},
create: function(req,res,next){
Course.create(req.params.all(), function courseCreated (err, course){
if(err) next(err);
res.json(course)
});
}
};

我正在尝试从 Python 客户端调用在 .Net Core 项目上运行的 GRPC 服务器。
当针对localhost:5001它运行时工作正常,但针对同一网络内机器的实际 IP 运行时,192.168.1.230:5001它不起作用,并且出现错误DNS resolution failed。
我已经下载了 SSL 证书,目前正在从客户端将其作为文件读取。它在对抗时有效,localhost所以我认为这不是问题。
有没有更好的方法来进行这种让客户端在单独的设备上运行但与服务器在同一网络上的测试?在开发过程中将 GRPC 服务器托管在外部似乎并不是最好的解决方案。

def main():

cert = file.read()

我可以让吐司弹出,所以 onclicklistener 似乎正在工作。但是,导航部分不起作用。如果我只是在托管 recyclerview 的片段内设置一个按钮并添加button.setOnClickListener(Navigation.createNavigateOnClickListener(R.id.workoutDetailsFragment))它可以很好地导航。所以问题似乎是从 onbindviewholder 内的 onclicklistener 内部调用导航功能
