边缘不支持 API 调用'tabs.captureVisibleTab'

Question

我在Windows 10 V1703上使用Edge，构建15063.296。文档(https://learn.microsoft.com/en-us/microsoft-edge/extensions/api-support/support--apis(epapi api tabs.capturevisibletab可用。

但是当我在后台脚本中使用它时，我会收到以下错误：

api调用'tabs.capturevisibletab'不支持边缘。

代码是：

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

我错过了什么吗？

在我的fsbackground.js页面中，我致电：

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

该功能从Edge 15开始支持。在以前的版本上，它仍然没有支持，即使文档说的话有所不同。

确保下载最新版本的Microsoft Edge扩展工具包，并使用它再生桥梁文件。

您可以查看生成的bougchscriptsapibridge.js文件以查看发生了什么。

上一个版本(未支撑(：

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");
}
