是的,您可以实现这一点,但您需要创建自己的WRun
并使用addEntryPoint
. 这实际上在教程中提到,如下所示:
WRun() 内部
WRun() 实际上是一个方便的函数,它创建和配置一个 WServer 实例。如果你想要更多的控制,例如如果你有多个“入口点”,或者想要控制服务器的启动和停止,你可以直接使用 WServer API。
这里有一个示例,两个应用程序都是 Hello World 应用程序,但请注意它们在按钮上以及按下它们时具有不同的标题和不同的消息。WRun
您可以找到onsrc/http/Serve.C
和的另一个实现src/Wt/WServer
。

编译它
g++ -g -o two_helloworlds two_helloworlds.cc -I/usr/local/include -L/usr/local/lib -lwthttp -lwt -lboost_random -lboost_regex -lboost_signals -lboost_system -lboost_thread -lboost_filesystem -lboost_program_options -lboost_date_time
并执行
./two_helloworlds --docroot . --http-address 0.0.0.0 --http-port 8080
localhost:8080
您将访问其中一个应用程序,您localhost:8080/second
将访问另一个应用程序。
