坏状态:平台不允许使用不安全的HTTP: [英] Bad state: Insecure HTTP is not allowed by platform:

问题描述

我遇到以下问题:E/flutter(7144):[ERROR:flutter/lib/ui/ui_dart_state.cc(177)]未处理的异常:错误状态:平台不允许使用不安全的HTTP:http://myIPv4:PORT/PATH.

I'm having the following problem: E/flutter ( 7144): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: Bad state: Insecure HTTP is not allowed by platform: http://myIPv4:PORT/PATH.

这是我可以访问的后端:

And this is the backend that I can access:

我已经允许通过cors进行访问，但这甚至对我没有帮助.我已经尝试使用http://localhost:port/path和http://myIP:port/path，但是没有用！

I already allowing the access by cors, but not even this help me. I already tried to use the http://localhost:port/path and http://myIP:port/path but doesn't worked!

但是，如果我尝试直接通过浏览器访问，就可以工作.

But if I try access directly by browser so work.

推荐答案

对于Android:

以下迁移指南可能会省略此行为: https://flutter.dev/docs/release/breaking-changes/network-policy-ios-android .

或...只需添加 android/app/src/main/AndroidManifest.xml:

or... Just add in android/app/src/main/AndroidManifest.xml:

android:usesCleartextTraffic ="true" 到< application/> 的同时，也不要忘记使用 INTERNET 权限:

android:usesCleartextTraffic="true" to <application /> also dont forget to take INTERNET PERMISSION:

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

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="receipt"
        android:usesCleartextTraffic="true" <!-- This Line -->
        android:icon="@mipmap/ic_launcher">

对于iOS:

允许iOS上的整个应用程序全局使用不安全/HTTP请求，您可以将其添加到主词典定义下的 ios/Runner/info.plist :

<key>NSAppTransportSecurity</key>
<dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
</dict>

请注意，启用此功能时，您需要向Apple审核小组说明，否则您的应用将在提交后被拒绝.

Be warned that you will need to have an explanation for Apple's review team when enabling this, otherwise your app will get rejected on submission.

谢谢.
