api权限

Many of the functionalities that we're translated from mobile to the web require permission from the user.  Think about geolocation, audio/video access (think [getUserMedia for camera access][getUserMedia for camera_access]), and likewise APIs.  We can probably all agree that requiring permission for access to these APIs is a good thing, but I see a problem:  there's sometimes no way to access each APIs permission level without triggering a request to the user to get that information.  Obtrusive to say the least!

我们从手机到网络的许多功能都需要得到用户的许可。 考虑一下地理位置，音频/视频访问( [对于摄像头访问][getUserMedia for camera_access] ，请考虑使用[getUserMedia][getUserMedia for camera_access] )，以及类似的API。 我们可能都同意，要求获得对这些API的访问权限是一件好事，但我看到一个问题：有时，在不触发用户获取该信息的请求的情况下，无法访问每个API的权限级别。 至少可以这么说！

I recently discovered the [Permissions API][] which provides a method to query the permission level for an API without trigger a request to the user for access.  Let's look at a simple example:

最近，我发现了[Permissions API][] ，它提供了一种查询API权限级别的方法，而无需触发用户访问请求。 让我们看一个简单的例子：

// Get the geolocation status (starts out as "prompt")
    // ... meaning the user will be shown an access request if we want it
    navigator.permissions.query({ name: 'geolocation' }).then(function(result) {
        /* result.status = "prompt" */
    });
    
    // Request geolocation access if we really want it
    navigator.geolocation.getCurrentPosition(function(result) { /* ... */  })
    
    // Assuming the user requested access, the permission is now "granted"
    navigator.permissions.query({ name: 'geolocation' }).then(function(result) {
        /* result.status = "granted" */
    });
    
    // Push notifications require options:
    navigator.permissions.query({ name: 'push', userVisibleOnly:true }).then(function(result) { /* ... */ });

I love this new API -- a clear path for getting a permission level without needing to request any information from the user. For example: if the permission level is negative, don't ask the user permission to do something, or prompt the user in another fashion to allow a given permission.

我喜欢这个新的API，这是获取权限级别的清晰路径，而无需从用户那里请求任何信息。 例如：如果权限级别为负，则不要要求用户权限做某事，也不要以其他方式提示用户允许给定权限。

Do you see another advantage to this API? Share!
