Question

我在Windows 10 v1703上使用Edge，构建15063.296。文档（https://docs.microsoft.com/en-us/microsoft-edge/extensions/api-support/supported-apis）声明API tabs.captureVisibleTab可用。

但是当我在后台脚本中使用它时，我收到以下错误：

边缘不支持API调用'tabs.captureVisibleTab'。

代码是：

browser.tabs.captureVisibleTab(currentTab.windowId, {format: "png"}, function (data) {});

我错过了什么吗？

UPDATE：

这是我的清单文件（从Chrome移植）：

在我的fsBackground.js页面中，我打电话：

     browser.tabs.captureVisibleTab(windowId, {format: "png"}, function (data) {});

我收到以下错误：click to see screenshot...

支持该功能starting from Edge 15。在以前的版本中，它仍然不受支持，即使文档说的不同。

确保下载最新版本的Microsoft Edge Extension Toolkit并使用它重新生成桥文件。

您可以查看生成的backgroundScriptsAPIBridge.js文件以查看更改内容。

以前的版本（不支持）：

captureVisibleTab(windowId, options, callback) {
    bridgeLog.LogUnavailbleApi("tabs.captureVisibleTab");
}

新版本（支持）：

captureVisibleTab(windowId, options, callback) {
    bridgeLog.DoActionAndLog(() => {
        myBrowser.tabs.captureVisibleTab.apply(null, arguments);
    }, "tabs.captureVisibleTab");
}

Edge中不支持API调用'tabs.captureVisibleTab'
