react native android9 axios network error
react native 发布成apk后网络请求会报 network error 是因为android9以后http协议不能用,要用htts协议。需要改成配置能兼容http协议,修改信息如下:
android:networkSecurityConfig="@xml/network_security_config"
android\app\src\main\res 目录新增两个文件 network_security_config.xml 和 update_file_provider.xml 配置信息如下
<?xml version="1.0" encoding="utf-8"?> <network-security-config> <base-config cleartextTrafficPermitted="true"> <trust-anchors> <certificates src="system" /> </trust-anchors> </base-config> </network-security-config>
<?xml version="1.0" encoding="utf-8"?> <paths xmlns:android="http://schemas.android.com/apk/res/android"> <!--升级--> <!--<external-cache-path name="update_external_cache" path="." />--> <!--<cache-path name="update_cache" path="." />--> <!--代表设备的根目录new File("/");--> <root-path name="root" path="" /> <!--context.getFilesDir()--> <files-path name="files" path="Android/data/com.xtzh/files/Download" /> <!--context.getCacheDir()--> <cache-path name="cache" path="." /> <!--Environment.getExternalStorageDirectory()--> <external-path name="external" path="Android/data/com.xtzh/files/Download" /> <!--context.getExternalFilesDirs()--> <external-files-path name="update_cache" path="Download" /> <!--getExternalCacheDirs()--> <external-cache-path name="update_external_cache" path="." /> </paths>
