javascript - 从 Angular Controller 发布到 Node

Question

好吧，我不明白这里发生了什么，在本地工作但在我的服务器上不工作。

我有一个发布到我的 Node 服务器的 Angular Controller 。

每次我尝试运行触发我得到的帖子的函数时

POST http://www.mysite.co.uk/mm3/back-end/savephotos 404 (Not Found)

老实说我迷路了，我重写了 5 次我找不到问题。

如果有人能看出我哪里出了问题，请帮忙。

Angular Controller

mm3\js\controller.js

 //all photos've been pushed now sending it to back end
                    $timeout(function () {
                        $http.post('back-end/savephoto', $scope.photosToPhp).then(function (success) {
                            $scope.generating = false;
                            $scope.generateBtn = 'Generate';
                            //creating mock up gallery
                            for (var x = 0; x < success.data.photos; x++) {
                                var file = '/mm3/tmp/' + success.data.folder + "/out" + x + ".png";
                                $scope.gallery.push(file);
                            }
                            $scope.photosToPhp = [];
                        }, function (error) {
                        });

                    }, 800);

然后是我的 Node 后端

更新: 所以我在我的函数中添加了一些控制台日志，以查看它哪里出了问题以及它到达了哪里。我不断得到:

test 1 function started error saving photo

mm3\back-end\controller.js

     app.post('/mm3/back-end/savePhoto', function (req, res) {
    console.log('test 1 function started');
    var folder = Math.random().toString(36).substr(2, 20);
    var photos = req.body;
    var counts = 0;
    var callback = function(counts){
        if(counts < photos.length){
            saveBase64(photos[counts],folder,counts,callback);
            console.log('test 2 save photo');
        }else{
            var counts = 0;
            var response = {"folder":folder, "photos": photos.length};
            console.log('test 3 save photo else');
            res.send(response)
        }
    };
    saveBase64(photos[counts],folder,counts,callback);
});

app.post('/mm3/downloadZip', function(req, res){
    var photos = req.body;
    var out =  photos[0];
    var test = out.split('/');
    var loc  = test.pop();
    var end =  test.join('/');
    console.log('test 3 function Generate zip file');
    console.log(end);
    var outName = '/' + end +'/mm3/MockUp.zip';
    var output = fs.createWriteStream(outName);
    var archive = archiver('zip', {store: true });
    var zip = function(photos, f){
        for(var t = 0; t < photos.length; t++){
            var file = 'mockUp'+ t +'.jpg';
            var from = '/var/www/html' +  photos[t];
            archive.file( from, { name: file });
        }
        f();
    };

    output.on('close', function() {
        var photos = req.body;
        var out =  photos[0];
        var test = out.split('/');
        var loc  = test.pop();
        var end =  test.join('/');
        res.send(end + '/MockUp.zip');
        console.log('archiver has been finalized and the output file descriptor has closed.');
    });
    archive.on('error', function(err) {
        throw err;
    });

    archive.pipe(output);
    zip(photos, f);
    function f(){
        archive.finalize();
    }
});

function saveBase64(photo,folder, counts, callback){
    var result = photo.split(',')[1];
    var path = '/mm3/tmp/' + folder;
    var filename = path + "/out"+ counts + ".png";
    mkdirp( path, function() {

        fs.writeFile(filename, result, 'base64', function(error){
            if (error) {
                console.log('error saving photo');
            }else{
                console.log('photo saved');
                counts ++;
                callback(counts);
            }
        });
    });
}

我认为这是问题所在:

app.post('back-end/savephoto', function (req, res) {
    // skipped some lines
});

改成

app.post('/back-end/savephoto', function (req, res) {
        // skipped some lines
    });
