Express.js多种方法 [英] Express.js multiple methods

问题描述

因此在Express中，您可以执行以下操作:

So in Express you can do:

app.get('/logo/:version/:name', function (req, res, next) {
    // Do something
}    

和

app.all('/logo/:version/:name', function (req, res) {
    // Do something
}    

是否只有两种方法(即GET和HEAD)?如:

Is there a way to just have two methods (ie. GET and HEAD)? Such as:

app.get.head('/logo/:version/:name', function (req, res, next) {
    // Do something
}    

推荐答案

只需拔出匿名函数并为其命名:

Just pull out the anonymous function and give it a name:

function myRouteHandler(req, res, next) {
  // Do something
}

app.get('/logo/:version/:name', myRouteHandler);
app.head('/logo/:version/:name', myRouteHandler);

或使用常规的中间件功能并检查req.method:

Or use a general middleware function and check the req.method:

app.use('/logo/:version/:name', function(req, res, next) {
  if (req.method === 'GET' || req.method === 'HEAD') {
    // Do something
  } else
    next();
});
