将 v8::String 转换为 LPCWSTR? [英] Convert v8::String to LPCWSTR?

问题描述

所以我从运行时传递一个字符串值作为函数参数:

So I'm passing a string value as function argument from runtime:

Handle<Value> xObj::Whatever(const Arguments& args){ ... // etc.

args[0] 绝对应该是字符串:

      if(!args[0]->IsString()) { ThrowException(... // etc.

既然我们有了它，我如何将它转换成一些有用的东西，比如 LPCWSTR、wchar_t、char[] 或其他什么?

Now that we have that, how do I convert it into something useful like LPCWSTR, wchar_t, char[] or whatever?

      MessageBox(NULL, args[0], L"Your value, sir.",0); // no way
      MessageBox(NULL, args[0]->ToString(), L"Your value, sir.",0); // also no
      /// then how?

推荐答案

v8::String::Value(args[0]) can be cast to a uint16_t const*code>，它要么是，要么可以转换为 LPCWSTR.(这取决于编译器设置/Zc:wchar_t-)

v8::String::Value(args[0]) can be casted to a uint16_t const*, which either is, or can be casted to LPCWSTR. (This depends on compiler setting /Zc:wchar_t-)
