前言:thrift的版本问题比较麻烦,高版本的在c++上需要c++ 11的支持,而低版本则可能在go的支持上有问题,测试发现thrift 9.0以上需要c++ 11,而thrift 8.0则在go的支持上可能会存在问题。使用的发行版本是CentOS 6.5,GCC 4.4.7。最终选择使用thrift-0.8.0来编译安装。
一. 编译安装 wget tar -zxvf thrift-0.8.0.tar.gz cd thrift-0.11.0 ./configure #这一步配置可以选择支持的语言,如Python,c++,go等。可以./configure --help来查看可配置项。如./configure --without-go make && make install注意:在执行完configure后,会显示实际上支持的库,比如
thrift 0.11.0 Building C (GLib) Library .... : no Building C# (Mono) Library ... : no Building C++ Library ......... : yes Building D Library ........... : no Building Dart Library ........ : no Building dotnetcore Library .. : no Building Erlang Library ...... : no Building Go Library .......... : no Building Haskell Library ..... : no Building Haxe Library ........ : no Building Java Library ........ : no Building Lua Library ......... : no Building NodeJS Library ...... : no Building Perl Library ........ : no Building PHP Library ......... : no Building Plugin Support ...... : no Building Python Library ...... : yes Building Py3 Library ......... : yes Building Ruby Library ........ : no Building Rust Library ........ : no如果编译没问题,那么就可以查看一下版本thrift -version,如果能显示,那么就ok。
二. 测试使用安装完后要搞一个小程序测试一下。thrift的使用是从.thirft文件开始的。
安装完后,自带的tutorial就有小例子,但感觉不够直观,来copy一个试试效果。
step 1 编写thrift文件 yang.thrift
struct Student{ 1: i32 sno, 2: string sname, 3: bool ssex, 4: i16 sage, } service Serv{ void put(1: Student s), i32 icall(1: Student s), string scall(1: Student s), /* string& srcall(1: Student s), ----------------------------- -thrift -r --gen cpp student.thrift -error: - [ERROR:/root/test/thrift/student.thrift:12] (last token was '&') - syntax error - [FAILURE:/root/test/thrift/student.thrift:12] Parser error during include pass. ----------------------------- */ Student stcall(1: Student s), }
step 2 生成源代码
比如要生成c++代码,就可以 thrift -r --gen cpp yang.thrift。这样就能在目录下生成一个gen-cpp目录,里面生成了多个文件,其中的Serv_server.skeleton.cpp就是服务器端main函数入口文件。--gen后指定生成的语言,yang.thrift就是编写的thrift魔板。
step 3 编写客户端代码
step 2 生成了服务器端的代码框架(也仅仅是个框架),但是客户端的代码就要自己编写了。
#include "Serv.h" //这里包含的是服务器端生成的头文件,注意路径 #include <transport/TSocket.h> #include <transport/TBufferTransports.h> #include <protocol/TBinaryProtocol.h> using namespace apache::thrift; using namespace apache::thrift::protocol; using namespace apache::thrift::transport; using boost::shared_ptr; int main(int argc, char **argv) { boost::shared_ptr<TSocket> socket(new TSocket("localhost", 9090)); boost::shared_ptr<TTransport> transport(new TBufferedTransport(socket)); boost::shared_ptr<TProtocol> protocol(new TBinaryProtocol(transport)); transport->open(); //调用server服务 Student s; s.sno = 123; s.sname = "hao973"; s.ssex = 1; s.sage = 30; ServClient client(protocol); printf("sno=%d sname=%s ssex=%d sage=%d\n", s.sno, s.sname.c_str(), s.ssex, s.sage); //put client.put(s); //icall scall std::string strname = ""; client.scall(strname, s); printf("icall=%d, scall=%s\n", client.icall(s), strname.c_str()); //stcall client.stcall(stu, s); printf("student sno=%d sname=%s ssex=%d sage=%d\n", stu.sno, stu.sname.c_str(), stu.ssex, stu.sage); transport->close(); return 0; }
step 4 修改填充服务器端的代码
这里主要是填充服务的方法实现。在Serv_server.skeleton.cpp文件put中添加printf(“sno=%d sname=%s ssex=%d sage=%d\n”, s.sno, s.sname.c_str(), s.ssex, s.sage);。其他几个函数也是如此添加。下面是最后的结果。
#include "Serv.h" #include <thrift/protocol/TBinaryProtocol.h> #include <thrift/server/TSimpleServer.h> #include <thrift/transport/TServerSocket.h> #include <thrift/transport/TBufferTransports.h> using namespace ::apache::thrift; using namespace ::apache::thrift::protocol; using namespace ::apache::thrift::transport; using namespace ::apache::thrift::server; using boost::shared_ptr; class ServHandler : virtual public ServIf { public: ServHandler() { // Your initialization goes here } void put(const Student& s) { // Your implementation goes here printf("put\n"); printf("sno=%d sname=%s ssex=%d sage=%d\n", s.sno, s.sname.c_str(), s.ssex, s.sage); } int32_t icall(const Student& s) { // Your implementation goes here printf("icall\n"); printf("sno=%d sname=%s ssex=%d sage=%d\n", s.sno, s.sname.c_str(), s.ssex, s.sage); return s.sage; } void scall(std::string& _return, const Student& s) { // Your implementation goes here printf("scall\n"); printf("sno=%d sname=%s ssex=%d sage=%d\n", s.sno, s.sname.c_str(), s.ssex, s.sage); _return = s.sname; } void stcall(Student& stu, const Student& s) { // Your implementation goes here printf("stcall\n"); printf("sno=%d sname=%s ssex=%d sage=%d\n", s.sno, s.sname.c_str(), s.ssex, s.sage); stu.sno = s.sno + 1; stu.sname = s.sname + "123"; stu.ssex = s.ssex; stu.sage = s.sage + 10; } }; int main(int argc, char **argv) { int port = 9090; shared_ptr<ServHandler> handler(new ServHandler()); shared_ptr<TProcessor> processor(new ServProcessor(handler)); shared_ptr<TServerTransport> serverTransport(new TServerSocket(port)); shared_ptr<TTransportFactory> transportFactory(new TBufferedTransportFactory()); shared_ptr<TProtocolFactory> protocolFactory(new TBinaryProtocolFactory()); TSimpleServer server(processor, serverTransport, transportFactory, protocolFactory); server.serve(); return 0; }
