C++用LuaIntf调用Lua代码示例
(金庆的专栏 2016.12)
void LuaTest::OnResponse(uint32_t uLuaRpcId,
const std::string& sRespContent) const
{
using LuaIntf::LuaRef;
LuaRef require(m_pLuaState, "require");
try {
LuaRef handler = require.call<LuaRef>("client_rpc_response_handler");
handler.dispatchStatic("handle", uLuaRpcId, sRespContent);
}
catch (const LuaIntf::LuaException& e) {
std::cerr << "Failed to call lua client_rpc_response_handler.handle(), "
<< e.what() << std::endl;
}
}
const std::string& sRespContent) const
{
using LuaIntf::LuaRef;
LuaRef require(m_pLuaState, "require");
try {
LuaRef handler = require.call<LuaRef>("client_rpc_response_handler");
handler.dispatchStatic("handle", uLuaRpcId, sRespContent);
}
catch (const LuaIntf::LuaException& e) {
std::cerr << "Failed to call lua client_rpc_response_handler.handle(), "
<< e.what() << std::endl;
}
}
这是测试客户端代码，可以写Lua代码测试服务器．
Lua代码中发出一个Rpc请求时, 会在Lua中保存一个回调, 待收到应答时触发回调. 通过uLuaRpcId来索引该回调.
sRespContent 是收到的应答包, 将在lua中解包.
OnResponse() 就是调用了 Lua 代码:
require("client_rpc_response_handler").handle(uLuaRpcId, sRespContent)
