是否可以在ExpressJS中禁用/删除特定路由的中间件？ [英] Is it possible to disable/remove a middleware for specific route in ExpressJS?

问题描述

我想禁用以前在app.js中设置的特定中间件，例如：

I want to disable a specific middleware, which I've set up previously in the app.js, for example:

app.use(express.bodyParser());

然后我想删除那个 bodyParser（）例如：

And then I want to remove that bodyParser() for a specific route for instance:

app.post("/posts/add", Post.addPost);

谢谢

推荐答案

您可以编写一个函数来检测条件，如下所示：

You could write a function to detect a condition, like this:

function maybe(fn) {
    return function(req, res, next) {
        if (req.path === '/posts/add' && req.method === 'POST') {
            next();
        } else {
            fn(req, res, next);
        }
    }
}

然后修改应用程序。使用语句：

And then modify the app.use statement:

app.use(maybe(express.bodyParser()));
