我做了一个这样的简单节俭文件:
thrifttest.thrift
namespace cpp thrifttest
namespace d thrifttest
namespace java thrifttest
namespace php thrifttest
namespace perl thrifttest
service Test {
list<i64> ping();
}
并在 shell 中运行“thrift --gen cpp thrifttest.thrift”
但是,当我查看 gen-cpp/Test_server.skeleton.cpp 时,它使 i64 列表成为参数,而不是返回类型:
Test_server.skeleton.cpp(摘录)
void ping(std::vector<int64_t> & _return) {
// Your implementation goes here
printf("ping\n");
}
在我的 server.cpp 程序中,在我创建一个返回“std::vector &”的函数 ping() 之后,编译器抱怨说
错误:无法分配抽象类型“TestHandler”server.cpp:30:7 的对象:注意:因为以下虚函数在“TestHandler”中是纯的:
这是 server.cpp server.cpp的完整代码
