How do I get permission to navigator.getusermedia via webview in cordoba?

Question

I want to develop Android through cordova webview on the web made with HTML. However, cordova is not allowed in navigator.getusermedia. Is there a way?

Answer 1

您可以通过cordova-diagnostic-plugin

请求使用相机的运行时权限

• 将诊断插件安装到您的项目中
  • cordova plugin add cordova.plugins.diagnostic
• 将cordova-custom-config插件安装到您的项目中
  • cordova plugin add cordova-custom-config

• 为config.xml添加相机权限的清单条目（请参阅Android permissions）：

  <platform name="android">
      <config-file target="AndroidManifest.xml" parent="/*">
          <uses-permission android:name="android.permission.CAMERA" />
      </config-file>
  </platform>
  

• Request camera authorization在运行时：

  document.addEventListener('deviceready', function(){
      cordova.plugins.diagnostic.requestCameraAuthorization(
          function(status){
              if(status == cordova.plugins.diagnostic.permissionStatus.GRANTED){
                  // permission granted - use camera
                  var video = document.querySelector('video');
  
                  if (navigator.getUserMedia) {
                      navigator.getUserMedia({audio: true, video: true}, function(stream) {
                          video.src = window.URL.createObjectURL(stream);
                      }, function(e){
                          console.log("Error:" + e);
                      });
                  } else {
                      console.log("No media available");
                  }
              }else{
                  // permission denied - inform user
              }
          }, function(error){
              console.error("The following error occurred: "+error);
          }, false
      );  
  }, false);
