我有这个用于分享照片的网络应用程序.
现在我有这条路线应该从以下数组返回所有用户的照片.
路线:
router.get('/getphotos',function(req, res){
var reqPhotos = [];
console.log( "\n" + req.body.username + "\n");
try{
for(x =0; x < req.body.following.length; x++){
reqPhotos.push({username: req.body.following[x].username});
}
}
catch(err){
console.log(err);
}
Photo.find({username: reqPhotos}).exec(function(err, allPhotos){
if(err){console.log(err);}
else{
res.json(allPhotos);
}
});
});

我发现req.body.following是未定义的.这是我用angular调用它的方式:
$scope.getPhotos = function(){
if($scope.identification){
flng = angular.copy($scope.identification.following);
flng.push($scope.identification.username);
var data = {username: $scope.identification.username, token: $scope.identification.token, following: flng}
//IDENTIFICATION HAS ALL THE INFO.
$http.get('/users/getphotos', data).success(function(response){
$scope.photos = response;
});
}
}

为什么会发生这种情况以及如何解决?
谢谢!
不确定服务器端,但我看到角度代码中有两个问题.在执行HTTP GET请求时,您无法传递正文.尝试通过网址传递任何必要的数据.
此外,返回的实际数据将在response.data.做这样的事情:
var urlData = ""; //add any url data here, by converting 'data' into url params
$http.get('/users/getphotos/' + urlData).then(function(response){
$scope.photos = response.data;
});

要构建urlData,请查看此问题.
当然,您必须调整服务器,以便从URL中读取数据,而不是从正文中读取数据.
