无法弄清楚为什么找不到角形链接

Question

I am sending a request

$http.get('/loadpage?category='+$scope.selectedCategory+'&page='+$scope.selectedPage).then(function(response){

    }).catch(function(){
        console.log("Error caught!");
    });

On my router.js file,

I have

router.get('/loadpage?category=xx&page=yy', function(req, res) {

res.send("Is this working");
});

I am not sure why my server is showing the following error.

angular.js:12587 GET http://localhost:3000/loadpage?category=1&page=1 404 (Not Found)

Because I tried sending a request to another url

router.get('/runthis/category=:xx',function(req, res){
var p = req.params.xx;

res.send(p);
});

by

function runthis (){
    $http.get('runthis/category=smackthat').then(function(response){
        console.log(response.data);
    }).catch(function(){
        console.log("Error caught!");
    });
}

And it works perfectly.

Can anyone help. Thanks

Answer 1

您正在对查询字符串（URL的?foo=bar部分）进行操作，以表示查询字符串已解析为req.query，例如req.query.foo === 'bar'因此路由应为/loadpage和您应该从req.query获取数据

Answer 2

Why don't you make your url a bit simpler such as :

router.get('/loadpage/:category/:page', function(req, res) {
   res.send("Is this working");
});

Makes your url parameters more semantic. and call it as :

$http.get('/loadpage/'+$scope.selectedCategory+'/'+$scope.selectedPage).then(function(response){

}).catch(function(){
    console.log("Error caught!");
});

Also, when you defined your url without : in router.get('/loadpage?category=xx&page=yy'... The router is looking for an exact match for the called url, in your case, you are passing variables and unless those 2 have xx and yy in them respectively, it's working as expected and throwing 404
