// 然后就可以把这个类型构造成std::string类型了。 std::string value = std::string(*String::Utf8Value(isolate, args[0])); // 从C++字符串转为js字符串用到了String::NewFromUtf8()函数,传入C风格字符 args.GetReturnValue().Set(String::NewFromUtf8(isolate, value.c_str())); } 1. 2. 3...
1. 在c++层通用逻辑中我们讲过相关的知识,这里就不详细讲述了,当我们在js层new UDP的时候,会新建一个c++对象。 UDPWrap::UDPWrap(Environment* env, Local object) : HandleWrap(env, object, reinterpret_cast(&handle_), AsyncWrap::PROVIDER_UDPWRAP) { int r = uv_udp_init(env->event_loop(), &h...

The types are null, undefined, boolean, number, string, function, class, date and object. To access the results of the type inference, use class DataFlow::AnalyzedNode: any DataFlow::Node can be cast to this class, and additionally there is a convenience predicate Expr::analyze that maps ...

在最新的《在微控制器和物联网上使用JavaScript》的文章中,我们发现Espruino在Esp8266平台上非常受欢迎,Espruino的确很不错,但在EPS8266平台上还是非常有限的。Espruino提供了TLS支持,这一功能在其他硬件平台非常有用。在今天的这篇文章中,我们回到Particle Photon上来解决他的一个最大的缺点:缺少TLS支持,接下来我们将...
