jQuery ajax 请求有效，同样的 AngularJS ajax 请求无效 [英] jQuery ajax request works, same AngularJS ajax request doesn't

问题描述

我正在学习 AngularJS 并尝试构建从 Wordpress 获取数据的前端系统.

I'm learning AngularJS and trying to build front-end system that gets data from Wordpress.

在后端，一切似乎都设置正确，当我使用 jQuery ajax 请求时，它可以毫无问题地获取数据.

On the back-end side everything seems to be set up properly and when I use jQuery ajax request it gets the data without problems.

jQuery.ajax({
    type: 'POST',
    url: '/wp-admin/admin-ajax.php',
    data: {
        action: 'getdataajax'
    },
    success: function(data, textStatus, XMLHttpRequest){
        console.log(data);
    },
    error: function(MLHttpRequest, textStatus, errorThrown){
        console.log(errorThrown);
    }
});

但是当我尝试用 AngularJS 做同样的事情时，它不起作用.我正在尝试使用如下代码复制 ajax 请求:

But when I try to do the same thing with AngularJS, it does not work. I'm trying to replicate the ajax request with code like this:

myApp.factory('productsData', function($http, $log) {
    return {
        getProducts: function(successcb) {
            return $http({ 
                method: 'POST', 
                url: '/wp-admin/admin-ajax.php', 
                data: {action: 'getdataajax'}
            }).success(function(data, status, headers, config) {
                    successcb(data);
                    $log.info(data, status, headers(), config)

            }).error(function(data, status, headers, config) {
                    $log.warn(data, status, headers(), config)
            });
        },

    };
});

如果我记录它，它会输出 0.我错过了什么?

If I log it, it outputs 0. What am I missing?

感谢您的帮助.

附言控制器看起来像这样:

P.S. Controller looks like this:

myApp.controller('ProductsController', function ProductsController($scope, productsData) {

    $scope.sortorder = 'name';

    // $scope.products = productsData.products;
    // $scope.products = productsData.getProducts();

    productsData.getProducts(function(products){
        $scope.products = products;
    });
});

推荐答案

在 angularjs 代码中，使用 params: 而不是 data:.

In the angularjs code, use params: instead of data:.

在 jquery 中，提供给 data: 配置设置的对象将转换为查询字符串 (?key1=val1&key2=value2)，除非您设置 processData: false.在 angularjs 中，您必须使用 params: 来获取查询字符串，data: 作为 json 或字符串发送.

In jquery the object supplied to the data: config setting is converted to a query string (?key1=val1&key2=value2) unless you set processData: false. in angularjs, you have to use params: to get a query string, data: is sent as json or string.
