MeanJs：如何 POST 数据？为什么服务操作不触发？

Question

我是 angular 的新手，MeanJs 需要帮助。我做错了什么，如何 post 数据并得到答案？我想执行 Complile 函数并将代码从文本框传递到服务器并对其进行处理并获得答案。但是如何在lab.client.service.js或其他文件中编写代码？
因为我没有得到从文件 [3] 开始执行代码的任何信息。我使用 https://www.youtube.com/watch?v=DOqLbJTvCv8&feature=youtu.be 教程编写了这段代码。

文件

lab.client.view.html 我有文本框绑定到 data.code angular 对象
```
<textarea ng-model="data.code"></textarea>
```

并且在 :

中有两个带触发功能的按钮

<div style="margin:12px;">
<button type="button" class="btn btn-primary" ng-click="LabController.compile()">Compile</button>
<button type="button" class="btn btn-primary" ng-click="LabController.compileAndUpload()">Cimpile & Upload</button>
</div>

lab.client.controller.js

'use strict';

angular.module('core').controller('LabController', ['$scope', 'Lab',
function($scope, Lab) {
    $scope.data = {
        code: ''
    };

    this.compile = function() {
                console.log('User clicked compile', $scope.data.code);       //This message is printed in browser console.
        $scope.message = Lab.compile                                   //But this action does not executes???
    };

    this.compileAndUpload = function() {
                 console.log('User clicked compileAndUpload', $scope.data.code);    //This message is printed in browser console.
         $scope.message = Lab.compileAndUpload;             //But this action does not executes???
    };
}
]);

lab.client.service.js

'use strict';

angular.module('core').factory('Lab', ['$resource', function($resource) {
    console.info("client.service: Veikia!");
    return $resource('lab', {                           
        compile: {                     //I do not see that there URL were triggered
            method: 'POST',
            url: '/lab/compile'  
        },
        compileAndUpload: {   //I do not see that there URL were triggered
            method: 'POST',
            url: '/lab/compileAndUpload',               
        }
    });
}
]);

lab.server.routes.js

'use strict';

module.exports = function(app) {
var lab = require('../../app/controllers/lab.server.controller');

// Lab Routes
app.route('/lab/compile')
    .post(lab.compile);

app.route('/lab/compileAndUpload')
    .post(lab.compileAndUpload);
};

lab.server.controller.js

'use strict';

var mongoose = require('mongoose'),
_ = require('lodash');

var response = {
'message' : 'It works'
};

exports.compile = function(req, res) {
var code = req.body.data.code;
res.jsonp(response);
};

exports.compileAndUpload = function(req, res) { 
    var code = req.body.data.code; 
res.jsonp(response);
};

您的代码有两个问题：

自定义资源操作定义不正确。参见argument list。第二个参数用于默认参数：

return $resource('lab', {}, {  // <-- 3rd argument                          
 compile: {                     
    method: 'POST',
    url: '/lab/compile'  
 },
 compileAndUpload: {
    method: 'POST',
    url: '/lab/compileAndUpload',               
 }
});

在 $scope.message = Lab.compile 中，您正在分配操作而不是调用它：

this.compile = function() {
     console.log('User clicked compile', $scope.data.code);       //This message is printed in browser console.
     $scope.message = Lab.compile() // <-- invoke
};

this.compileAndUpload = function() {
     console.log('User clicked compileAndUpload', $scope.data.code);    //This message is printed in browser console.
     $scope.message = Lab.compileAndUpload();
};
