Phonegap跨域AJAX POST请求不适用于Android [英] Phonegap Cross-domain AJAX POST Request not working on Android

问题描述

跨域 AJAX POST 请求在 Web 浏览器(包括手机浏览器)上运行良好，但不适用于使用 Phonegap

Cross-domain AJAX POST request works perfectly fine on web browsers including browsers on mobile phones, but doesn't work for native applications built using Phonegap

我创建了一个登录表单，用户必须输入他们的登录凭据，然后由 heroku 上托管的服务器进行验证，如果凭据有效，则返回 json {"success":true}输入.

I have created a login form that users have to enter their login credentials, then they are verified by the server that is hosted on heroku and returns json {"success":true} if valid credentials are entered.

我的 Ajax 脚本:

$.ajax({
   type: "POST",
   url: "http://domain.com/public/auth/app-login",
   contentType: "application/x-www-form-urlencoded; charset=utf-8",
   dataType: "json",
   data: {identity: <username from form>, password: <password from form>},
   crossDomain: true,
   cache: false,
   success: function(data) {
       obj = JSON.parse(data);
       if (obj && obj.success === true) {
          window.location.href = 'home.html';
       }
   },
   error: function(e) {
       alert('Error: ' + e.message);
   }
});

为解决此问题所采取的步骤:

• 域白名单 - config.xml

• Domain whitelisting - config.xml

<代码><access origin="http://domain.com/public/auth/app-login"/>

<代码><access origin="*"/>

• 告诉 jQuery 允许跨域

<代码>$.support.cors = true;或者<代码>jQuery.support.cors = true;

• 禁用缓存 cache: false

推荐答案

好的.如果 index.html 在本地，那么你可以在任何主机上调用 ajax，不需要在客户端或服务器中启用 CORS.您删除:

Ok. If index.html in local then you can call ajax any hosts, not need enable CORS in client or server. You remove:

$.support.cors = true; OR jQuery.support.cors = true;

还有:

<access origin="http://domain.com/public/auth/app-login" />

多余，只用:

<access origin="*" />

您需要在 AndroidManifest.xml 中检查并添加:

You need check and add in AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />

如果您的应用需要，请添加更多权限.最后，在 $(document).ready() 中调用ajax:

Add more permission if your app required. Finally, call ajax inside $(document).ready():

$.ajax({
   type: "POST",
   url: "http://domain.com/public/auth/app-login",
   dataType: "json",
   data: {identity: <username from form>, password: <password from form>},
   success: function(data) {
     obj = JSON.parse(data);
     if (obj && obj.success === true) {
        window.location.href = 'home.html';
     }
   },
   error: function(e) {
     alert('Error: ' + e.message);
   }
});
