在Android Marshmallow中,当应用程序运行时用户会授予权限,而不是在安装应用程序时授予权限。因此,在Ionic中如何在运行时检查和授予权限?
cordova.plugins.diagnostic.getPermissionAuthorizationStatus(function(status){
switch(status){
case cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED:
console.log("Permission granted to use the camera");
break;
case cordova.plugins.diagnostic.runtimePermissionStatus.NOT_REQUESTED:
console.log("Permission to use the camera has not been requested yet");
break;
case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED:
console.log("Permission denied to use the camera - ask again?");
break;
case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED_ALWAYS:
console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
break;
}
}, function(error){
console.error("The following error occurred: "+error);
}, cordova.plugins.diagnostic.runtimePermission.CAMERA);
请求授权:
cordova.plugins.diagnostic.requestRuntimePermission(function(status){
switch(status){
case cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED:
console.log("Permission granted to use the camera");
break;
case cordova.plugins.diagnostic.runtimePermissionStatus.NOT_REQUESTED:
console.log("Permission to use the camera has not been requested yet");
break;
case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED:
console.log("Permission denied to use the camera - ask again?");
break;
case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED_ALWAYS:
console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
break;
}
}, function(error){
console.error("The following error occurred: "+error);
}, cordova.plugins.diagnostic.runtimePermission.CAMERA);
DaveAlden的解决方案是唯一一个对我有效的。请注意,此插件基于AndroidX,因此您需要安装以下文件:
ionic cordova plugin add cordova-plugin-androidx
ionic cordova plugin add cordova-plugin-androidx-adapter
然后您可以安装诊断插件文件:
ionic cordova plugin add cordova.plugins.diagnostic
npm install @ionic-native/diagnostic
还要记得在 app.module 的 providers 列表中添加 Diagnostic:
import { Diagnostic } from '@ionic-native/diagnostic/ngx';
...
providers: [..., Diagnostic]
最后,自从戴夫的答案以来,诊断插件的API已经发生了变化,所以这是目前的工作代码:
检查是否授予权限:
this.diagnostic.getPermissionAuthorizationStatus(this.diagnostic.permission.CAMERA)
.then((status) => {
switch(status){
case this.diagnostic.permissionStatus.GRANTED:
console.log("Permission granted to use the camera");
break;
case this.diagnostic.permissionStatus.NOT_REQUESTED:
console.log("Permission to use the camera has not been requested yet");
break;
case this.diagnostic.permissionStatus.DENIED:
console.log("Permission denied to use the camera - ask again?");
break;
case this.diagnostic.permissionStatus.DENIED_ALWAYS:
console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
break;
}
})
.catch((error) => {
console.error("The following error occurred: "+error);
});
请求权限:
this.diagnostic.requestRuntimePermission(this.diagnostic.permission.CAMERA)
.then((status) => {
switch(status){
case this.diagnostic.permissionStatus.GRANTED:
console.log("Permission granted to use the camera");
break;
case this.diagnostic.permissionStatus.NOT_REQUESTED:
console.log("Permission to use the camera has not been requested yet");
break;
case this.diagnostic.permissionStatus.DENIED:
console.log("Permission denied to use the camera - ask again?");
break;
case this.diagnostic.permissionStatus.DENIED_ALWAYS:
console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
break;
}
})
.catch((error) => {
console.error("The following error occurred: "+error);
});
