无法在Ionic 4中加载资源：net :: ERR_CLEARTEXT_NOT_PERMITTED

时间：2019-12-16 07:13:54

标签： angular ionic-framework ionic4

致电服务器时出现此错误。但是每次我打API调用（GET和POST）时，都会出现此错误上升Failed to load resource: net::ERR_CLEARTEXT_NOT_PERMITTE'D。否则该应用程序可以正常工作。它可以很好地加载资源和所有内容。有人知道如何解决此问题吗？它与服务器端有关还是与App前端方面有关？

service.ts文件

这样做

根据@nazehs的答案

https://forum.ionicframework.com/t/err-cleartext-not-permitted-in-debug-app-on-android/164101/31

config.xml 

<edit-config file="app/src/main/AndroidManifest.xml" 
   mode="merge" target="/manifest/application" 
   xmlns:android="http://schemas.android.com/apk/res/android">
     <application android:usesCleartextTraffic="true" />
     <application android:networkSecurityConfig="@xml/network_security_config" />
 </edit-config>
 <resource-file src="resources/android/xml/network_security_config.xml" 
 target="app/src/main/res/xml/network_security_config.xml" />

“ resources / android / xml / network_security_config.xml”。

您需要针对此错误使用此插件

https://ionicframework.com/docs/native/http

这项工作是给我的。

答案 2 :(得分：0)

您需要从服务器端而不是从应用程序修复标头安全性问题。 将此代码插入服务器端应用程序。

      "Access-Control-Allow-Origin": "*", 
      "Access-Control-Allow-Headers": "Origin, Content-Type, X-Auth-Token, Accept, Authorization, X-Request-With",
      "Access-Control-Allow-Credentials" : "true",
      "Access-Control-Allow-Methods" : "GET, POST, DELETE, PUT, OPTIONS, TRACE, PATCH, CONNECT"

也可以尝试以下一种方法： https://stackoverflow.com/a/57098014/9685038

此问题归因于Android的安全级别升级。
