V8 console.log 不打印

我正在尝试将 v8 嵌入到我的应用程序中，我正在查看 V8 环境中包含的内容（duktape 不包含控制台实现），并且似乎 v8 确实包含一个实现，但是当我调用console.log它不打印任何内容，而是只打印 undefined （我假设这是console.log）那么如何链接默认值呢？std::cout输出与console.log.

这是我目前的代码，我正在使用默认的 hello world 代码，稍加修改。

int main(int argc, char* argv[]) {
    // Initialize V8.
    v8::V8::InitializeICUDefaultLocation(argv[0]);
    v8::V8::InitializeExternalStartupData(argv[0]);
    std::unique_ptr<v8::Platform> platform = v8::platform::NewDefaultPlatform();
    v8::V8::InitializePlatform(platform.get());
    v8::V8::Initialize();
    // Create a new Isolate and make it the current one.
    v8::Isolate::CreateParams create_params;
    create_params.array_buffer_allocator =
        v8::ArrayBuffer::Allocator::NewDefaultAllocator();
    v8::Isolate* isolate = v8::Isolate::New(create_params);
    {
        v8::Isolate::Scope isolate_scope(isolate);
        // Create a stack-allocated handle scope.
        v8::HandleScope handle_scope(isolate);
        // Create a new context.
        v8::Local<v8::Context> context = v8::Context::New(isolate);
        // Enter the context for compiling and running the hello world script.
        v8::Context::Scope context_scope(context);
        {
            // Create a string containing the JavaScript source code.
            v8::Local<v8::String> source =
                v8::String::NewFromUtf8(isolate, R"(
                    console.log("does not print?")
                )",
                v8::NewStringType::kNormal)
                .ToLocalChecked();
            // Compile the source code.
            v8::Local<v8::Script> script =
                v8::Script::Compile(context, source).ToLocalChecked();
            // Run the script to get the result.
            v8::Local<v8::Value> result = script->Run(context).ToLocalChecked();
            // Convert the result to an UTF8 string and print it.
            v8::String::Utf8Value utf8(isolate, result);
            printf("%s\n", *utf8);
        }
    }
    // Dispose the isolate and tear down V8.
    isolate->Dispose();
    v8::V8::Dispose();
    v8::V8::ShutdownPlatform();
    delete create_params.array_buffer_allocator;

    std::cin.get();
    return 0;
}

我正在使用预构建的 v8 二进制文件here https://github.com/pmed/v8-nuget

请尝试以下操作：

• #include "src/debug/interface-types.h"
• 定义您自己的“控制台委托”类，派生自debug::ConsoleDelegate
• 覆盖您感兴趣的任何方法，例如void Log(const debug::ConsoleCallArguments& args, const v8::debug::ConsoleContext&) override;
• 实例化它并调用debug::SetConsoleDelegate(isolate, &your_console_delegate);创建你的后Isolate
