离子+角 - 如何避免＆QUOT; 404未找到（从高速缓存）QUOT;后POST请求？ [英] Ionic + Angular - How to avoid the "404 Not Found (from cache)" after POST request?
问题描述
这个问题是部分指着我的previous问题：
离子+角POST请求返回状态404
this question is partly pointing to my previous question : Ionic + Angular POST request return state 404
但我没能找到工作的解决方案。
But i wasn't able to find working solution.
问题在于以下几点：
如果我从移动应用的设备我总是得到响应404上运行的要求做的：
if I do request from the mobile app running on the device i always get response 404:
Request Method:POST
Status Code:404 Not Found (from cache)
Request Headersview source
Accept:application/json, text/plain, */*
Content-Type:text/plain
Origin:file://
User-Agent:Mozilla/5.0 (Linux; Android 4.4.2; Lenovo Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/30.0.0.0 Mobile Safari/537.36
Request Payloadview source
{,…}
但是，如果我在Chrome浏览器尝试使用邮差插件在桌面上了同样的要求，我总是得到响应200正是我需要的数据。
But if i tried the same request on the desktop using Postman plugin in the Chrome browser i always get response 200 with data what i need.
我认为这是由角HTTP方法，但在previous后问题引起我被发现，事实并非如此。
I thought that it was issue caused by Angular http method but in previous post i was noticed that is not true.
我怎样才能避免这种情况吗？我应该在请求期间或者在服务器端（PHP）设置一些头在应用程序的HTML，？
How can i avoid this please? Should i set some headers in HTML of the app, during the request or on the server side (PHP)?
任何意见非常感谢。
编辑：
我想还设置缓存：通过这样的方式虚假的：
I tried also set cache:false by this way:
$http({
method : 'POST',
url : $scope.remoteUrl,
data: postData,
headers: headersData,
cache: false,
timeout: 10000
// success response
})
但是，如果没有运气。
But without luck.

我只是碰到了同样的问题。这似乎它与科尔多瓦的新版本新的安全策略做。
I just ran into the same problem. It seems it has to do with a new security policy in new versions of Cordova.
下面是我如何解决它：
我安装科尔多瓦的白名单插件：
cordova plugin add cordova-plugin-whitelist
然后，添加内容政策在 index.html的作为元标签（使用您自己的主机或*接受所有请求）：
Then, add your content policy in your index.html as a meta tag (using your own host or '*' for accepting all requests) :
<meta http-equiv="Content-Security-Policy" content="default-src 'self' yourhost.com ws://localhost:35729 data: gap: https://ssl.gstatic.com; style-src 'self' 'unsafe-inline'; media-src *;script-src 'self' localhost:35729 'unsafe-eval' 'unsafe-inline';">
默认的src 用于一般要求;在 WS：//本地主机：35729 主机被用于实时重载的离子服务。
default-src is used for general requests; the ws://localhost:35729 host is used for live-reload in ionic serve.
脚本的src 用于安全执行脚本
不安全的内联和不安全-EVAL 要求，以便角正常工作。
unsafe-inline and unsafe-eval are required in order for angular to work properly.
数据：差距：https://ssl.gstatic.com 只用在iOS
自表示的当前主机的index.html 文件。
您必须添加自己为了您的要求工作。不要忘了，如果他们是非标准添加协议和端口号
You'll have to add your own in order for your requests to work. Don't forget to add the protocol and the port if they're non-standard
您可以跳过meta标签，如果你不想要它，但你会从白名单中的插件得到很多的警告。
You can skip the meta tag if you don't want it, but you'll get a lot of warnings from the whitelist plugin.
如何在
然后重建您的应用程序，它应该工作了。
Then rebuild your app, and it should work again.
