\n"推导成为const char const,而c++的char是不支持operator+操作的,这就导致了上面的编译错误。 此时,我们可以使用C++17之前的实例方法即显示指明类型,如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 intmain(){Add<std::string>ts("hello, ","world!\n");auto ret=ts.result();return0;} 如...

在声明的变量或参数前加上关键字 const 用于指明变量值不可被篡改 (如 const int foo ). 为类中的函数加上 const 限定符表明该函数不会修改类成员变量的状态 (如 class Foo { int Bar(char c) const; };). 但是,const 是入侵性的: 如果你向一个函数传入 const 变量, 函数原型声明中也必须对应 const ...

If we don't want a response without compression, we have to set Accept-Encoding to an empty string. This behavior is similar to curl.res = cli.Get("/resource/foo", {{"Accept-Encoding", ""}}); Compress request body on clientcli.set_compress(true); res = cli.Post("/resource/foo"...
