cpp char转string 文心快码BaiduComate 在C++中,将char转换为string是一个常见的操作。char类型可以表示单个字符,而std::string类型则可以表示一个字符串。以下是将char转换为std::string的几种常见方法: 使用std::string的构造函数: 可以直接将char作为参数传递给std::string的构造函数来创建一个新的std::string...

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"...
