我已经尝试了很多次来解决这个问题,但我一无所获。

此代码的主要目的是将密钥对(公共和私有)保存在嵌套类NslObject::KeyKNewKeyPair1.

.cpp 文件

        unsigned long int keyLength = 10;
        //KeyPair ADD(RSA::GenerateKeyPair(keyLength));
        NslObject::KeyK(RSA::GenerateKeyPair(keyLength));
        typedef NslObject::KeyK NewKeyPair1; 
        NewKeyPair1(RSA::GenerateKeyPair(keyLength));

        //NslObject::
        Key OtmanK(NslObject::Get_PublicKey(NewKeyPair1));

.h 文件:

     const  Key &GetPublicKey() const
            {
                    return Kk.GetPublicKey();
            }

       //KeyK  NewKeyPair ;


     };

     Key Get_PrivateKey(KeyK &K){
        return K.GetPrivateKey();
     }
      Key Get_PublicKey(KeyK &K){
        return K.GetPublicKey();
     }

virtual int     recv(ePacket_ *); 
virtual int     send(ePacket_ *); 
virtual int     get(ePacket_ *, MBinder *);
virtual int     put(ePacket_ *, MBinder *);
virtual ePacket_    *put1(ePacket_ *, MBinder *);
virtual int     command(int argc, const char *argv[]); 
virtual int     Debugger();


inline  void    set_port(u_int32_t portid) { 
        portid_ = portid; 
    };   
inline u_int32_t get_port() const { 
        return(portid_); 
    }; 
inline struct plist* get_portls() const {
        return(MPlist_);
    };
inline const char * get_name() const {
        return(name_);
    }
inline u_int32_t get_nid() const {
        return(nodeID_);
    }
inline u_int32_t get_type() const {
        return(nodeType_);
    }
    //--------------------------------------------------------





  };

所以,cpp文件中这一行的问题:

 Key OtmanK(NslObject::Get_PublicKey(NewKeyPair1));

当我试图编译这个项目时,我得到了这个错误信息:

 object.cc:87: error: expected primary-expression before ‘)’ token

请帮我。

当我尝试对关键类进行定向调用时,出现了另一个问题,例如:

        unsigned long int keyLength = 10;
        //KeyPair ADD(RSA::GenerateKeyPair(keyLength));
        NslObject::KeyK(RSA::GenerateKeyPair(keyLength));
        typedef NslObject::KeyK NewKeyPair1; 
        NewKeyPair1(RSA::GenerateKeyPair(keyLength));

        //NslObject::
        //Key OtmanK(NewKeyPair1.GetPublicKey());
        std::string message = "othman Alkilany";
        // NslObject::NewKeyPair.GetPrivateKey()
       std::string cypherText = RSA::Encrypt(  message, NewKeyPair1.GetPublicKey());

错误消息是:

  error: expected primary-expression before ‘.’ token

我想你的问题在这里的第二行:

typedef NslObject::KeyK NewKeyPair1; 
NewKeyPair1(RSA::GenerateKeyPair(keyLength));

解决 typedef 你基本上写了以下内容:

NslObject::KeyK(RSA::GenerateKeyPair(keyLength));

所以你可以清楚地看到你错过了这一行的变量名。

要解决此问题,请命名变量/对象:

NewKeyPair1 somekeypair(RSA::GenerateKeyPair(keyLength));

但是,我猜你还是误用typedef了?你试过命名NewKeyPair1吗?像这样的东西:

NslObject::KeyK NewKeyPair1(RSA::GenerateKeyPair(keyLength));
