来自 Cordova 的 REST 服务和 WAMP（本地）

Question

我正在尝试使用 WAMP（在本地）在 Web 服务（由我的 PrestaShop 网站准备）中提取产品。

我的代码： index.js

var app = {

  initialize: function() {
    this.bindEvents();
  },

  bindEvents: function() {
    this.onDeviceReady();
  },

  onDeviceReady: function() {
    var password = '';
    var key = 'F51Q7VWPRREG7TA25DEY8UIZT8V79E5V';
    var url = 'http://localhost/Test/prestashop/api/products?PHP_AUTH_USER="password"&ws_key="key"';

    $.ajax({
      type: "GET",
      dataType: "xml",
      url: url,
      success: this.onSuccess(data),
      error: this.onErreur()
      }); 
  },

  onSuccess: function(data) {
    alert("Success");
  },

  onErreur: function() {
    alert("Error");
  }
};

app.initialize();

![在此处输入图片描述][1]

我尝试用我的 IP 替换 localhost，但还没有成功。我没有提醒 "Success" 或 "Error"。我不明白为什么。我搜索了很多东西，都没有成功。

我用我的浏览器尝试了 index.html 和 index.js 并且它有效。

Answer 1

我也遇到过同样的问题。

我同意@Keval，你可能没有访问互联网的权限。

添加此插件 https://github.com/apache/cordova-plugin-whitelist 并转到您的 config.xml 文件。在这一行中，只需填写这一行，当然还有您的 IP 地址：

<allow-navigation href="http://xxx.xxx.xxx.xxx/*" />

这可能会解决问题，因为 <access origin="*" /> 还不够。（至少，对我来说还不够）

Answer 2

为了解决我的问题（将 Android 模拟器连接到 Wamp（本地）），我按照本教程进行操作：http://www.bradcurtis.com/hosts-files-and-the-google-android-emulator/
