WebAPI 是指一套设备兼容性和存储API. 它可以让Web Apps和其内容获取设备硬件(比如电池状态, 或者设备的振动器), 同时也可以获取设备上的数据(比如日历, 或者联系人等信息).

    By adding these APIs, we hope to expand what the Web can do today and only proprietary platforms were able to do in the past.

    Note: More of this documentation has been written than it looks like; links are not all added yet. We're actively working on improving this and expect to see things much better over the next couple of weeks. See the WebAPI doc status page, where we're tracking work on WebAPI docs.

    Note: For a brief explanation of each badge, please see the packaged apps documentation.

    Communication APIs

    Bluetooth Certification required
    The WebBluetooth API provides low-level access to the device's Bluetooth hardware.
    Mobile Connection API Certification required 非标准
    Exposes information about the device's cellular connectivity, such as signal strength, operator information, and so forth.
    Network Information API
    Provides basic information about the current network connection, such as connection speed.
    Network Stats API Certification required 非标准
    Monitors data usage and exposes this data to privileged applications.
    TCP Socket API Privileged 非标准
    Provides low-level sockets and SSL support.
    Telephony Certification required 非标准
    Lets apps place and answer phone calls and use the built-in telephony user interface.
    WebSMS Certification required 非标准
    Lets apps send and receive SMS text messages, as well as to access and manage the messages stored on the device.
    WiFi Information API Certification required 非标准
    A privileged API which provides information about signal strength, the name of the current network, available WiFi networks, and so forth.

    Hardware access APIs

    Ambient Light Sensor API
    Provides access to the ambient light sensor, which lets your app detect the ambient light level in the vicinity of the device.
    Battery Status API
    Provides information about the battery's charge level and whether or not the device is currently plugged in and charging.
    Camera API Certification required 非标准
    Allows apps to take photographs and/or record video using the device's built-in camera.
    Geolocation API
    Provides information about the device's physical location.
    Pointer Lock API
    Lets apps lock access to the mouse and gain access to movement deltas rather than absolute coordinates; this is great for gaming.
    Power Management API Certification required 非标准
    Lets apps turn on and off the screen, CPU, device power, and so forth. Also provides support for listening for and inspecting resource lock events.
    Proximity API
    Lets you detect proximity of the device to a nearby object, such as the user's face.
    Device Orientation API
    Provides notifications when the device's orientation changes.
    Screen Orientation API
    Provides notifications when the screen's orientation changes. You can also use this API to let your app indicate what orientation it prefers.
    Vibration API
    Lets apps control the device's vibration hardware for things such as haptic feedback in games. This is not intended for things such as notification vibrations. See the Alarm API for that.
    WebFM API installed 非标准
    Provides support for a device's FM radio functionality, if available.

    Data management APIs

    Contacts API Privileged
    Provides access to the user's contacts database, with support for adding, reading, and modifying contact information.
    Device Storage API Privileged 非标准
    Allows apps to create, read, and change files stored in a central location on the device, such as the "pictures" folder on modern desktop platforms or the photo storage on mobile devices.
    FileHandle API
    Provides support for writable files with locking support.
    Client-side storage of structured data with support for high-performance searches. Docs need moving.
    Settings API Certification required 非标准
    Lets apps examine and change system-wide configuration options that are permanently stored on the device.

    Other APIs

    Alarm API
    Lets apps schedule notifications. Also provides support for automatically launching an app at a specific time.
    Apps API 非标准
    The Open WebApps API provides support for installing and managing Web apps. In addition, support is provided to let apps determine payment information.
    Browser API Privileged 非标准
    Provides support for building a Web browser completely using Web technologies (in essence, a browser within a browser).
    Idle API Certification required
    Lets apps receive notifications when the user is not actively using the device.
    Permissions API Certification required 非标准
    Manages app permissions in a centralized location. Used by the Settings app.
    Simple Push API
    Lets the platform send notification messages to specific applications.
    Time/Clock API Certification required 非标准
    Provides support for setting the current time. The time zone is set using the Settings API.
    Web Activities 非标准
    Lets an app delegate an activity to another app; for example, an app might ask another app to select (or create) and return a photo. Typically the user is able to configure what apps are used for which activities.
    WebPayment API installed 非标准
    Lets Web content initiate payments and refunds for virtual goods.

    WebAPI community

    If you need help with these APIs, there are several ways you can talk to other developers making use of them.

    Don't forget about the netiquette...
