管理/删除工作WebView2的cookie

Question

我正在运行边缘WebView2的一些登录页面加载在那里。我想自动登录。

要做到这一点，我需要删除当前的cookie。我不能通过js做到这一点，因为它们是httponly。对于边缘测试版浏览器，我为删除cookie编写了简单的Chrome扩展，但是我不能在WebView2中运行一个扩展(或者可以吗？)

此外，我知道WebView2 cookie文件位于何处，但在运行Webview时无法更改它。

在WebView中这样做的唯一方法是打开DevTools，我在应用程序选项卡中删除了它们。

关于如何删除那个饼干有什么想法吗？

我希望至少有一个WebView2页面加载c++中带有自定义头的示例(在这里我可以指定cookies)。

您可以尝试在下面的代码中创建、更新和从WebView获取cookie

#include <string>
#include <tchar.h>
#include <wrl.h>
#include <wil/com.h>
#include "WebView2.h"
using namespace Microsoft::WRL;
std::wstring uri = L"https://developer.microsoft.com/en-us/microsoft-edge/webview2/";
static wil::com_ptr<ICoreWebView2Controller> webviewController;
static wil::com_ptr<ICoreWebView2> webview;
static wil::com_ptr<ICoreWebView2_2> webview2;
static wil::com_ptr<ICoreWebView2CookieManager> cookieManager;
static wil::com_ptr<ICoreWebView2Cookie> cookie;

void WebView2Initialise(HWND & hWnd)/*HWND of MainWindow, call this after Window initialisation */ {
//Create a single WebView within the parent window
//Locate the browser and set up the environment for WebView
CreateCoreWebView2EnvironmentWithOptions(nullptr, nullptr, nullptr,
Callback<ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler>(
        [hWnd](HRESULT result, ICoreWebView2Environment* env) -> HRESULT{

            // Create a CoreWebView2Controller and get the associated CoreWebView2 whose parent is the main window hWnd
            env->CreateCoreWebView2Controller(hWnd, Callback<ICoreWebView2CreateCoreWebView2ControllerCompletedHandler>(
                [hWnd](HRESULT result, ICoreWebView2Controller* controller) -> HRESULT {
                    if (controller != nullptr) {
                        webviewController = controller;
                        if (webviewController)
                        {
                            webviewController->get_CoreWebView2(&webview);
                            if (webview)
                            {
                                webview->QueryInterface(IID_PPV_ARGS(&webview2));
                                webview2->get_CookieManager(&cookieManager);
                            }

                    // Add a few settings for the webview
                    // The demo step is redundant since the values are the default settings
                    wil::com_ptr<ICoreWebView2Settings> settings;
                    
                    webview->get_Settings(&settings);
                    if (settings)
                    {

                    // Schedule an async task to navigate to Bing
                    webview->Navigate(uri.c_str());

                    if (cookieManager)
                    {
                        //Create Cookies
