提振。Program_options应该可以做到这一点

如果你不想使用boost，我推荐这个小助手类。

AnyOption是一个c++类，用于轻松解析复杂的命令行选项。它还以选项值对格式解析来自rsourcefile的选项。

AnyOption实现了传统的POSIX风格的字符选项(-n)以及较新的GNU风格的长选项(——name)。或者您可以通过要求忽略POSIX样式选项来使用更简单的长选项版本(-name)。

我认为GNU GetOpt并不是马上就可以使用的。

Qt和Boost可能是一种解决方案，但您需要下载并编译大量代码。

所以我自己实现了一个解析器，它产生一个std::map<std::string, std::string>的参数。

例如，调用:

 ./myProgram -v -p 1234

地图将是:

 ["-v"][""]
 ["-p"]["1234"]

用法是:

int main(int argc, char *argv[]) {
    MainOptions mo(argc, argv);
    MainOptions::Option* opt = mo.getParamFromKey("-p");
    const string type = opt ? (*opt).second : "";
    cout << type << endl; /* Prints 1234 */
    /* Your check code */
}

我可以建议使用模板化的c++命令行解析器库(GitHub上的一些分支是可用的)，API非常直接并且(引用自网站):

该库完全在头文件中实现，因此很容易 与其他软件一起使用和分发。它是MIT授权的 无后顾之忧的发行许可证。

这是手册中的一个例子，为了简单起见，这里有颜色:

#include <string>
#include <iostream>
#include <algorithm>
#include <tclap/CmdLine.h>

int main(int argc, char** argv)
{

    // Wrap everything in a try block.  Do this every time,
    // because exceptions will be thrown for problems.
    try {

    // Define the command line object, and insert a message
    // that describes the program. The "Command description message"
    // is printed last in the help text. The second argument is the
    // delimiter (usually space) and the last one is the version number.
    // The CmdLine object parses the argv array based on the Arg objects
    // that it contains.
    TCLAP::CmdLine cmd("Command description message", ' ', "0.9");

    // Define a value argument and add it to the command line.
    // A value arg defines a flag and a type of value that it expects,
    // such as "-n Bishop".
    TCLAP::ValueArg<std::string> nameArg("n","name","Name to print",true,"homer","string");

    // Add the argument nameArg to the CmdLine object. The CmdLine object
    // uses this Arg to parse the command line.
    cmd.add( nameArg );

    // Define a switch and add it to the command line.
    // A switch arg is a boolean argument and only defines a flag that
    // indicates true or false.  In this example the SwitchArg adds itself
    // to the CmdLine object as part of the constructor.  This eliminates
    // the need to call the cmd.add() method.  All args have support in
    // their constructors to add themselves directly to the CmdLine object.
    // It doesn't matter which idiom you choose, they accomplish the same thing.
    TCLAP::SwitchArg reverseSwitch("r","reverse","Print name backwards", cmd, false);

    // Parse the argv array.
    cmd.parse( argc, argv );

    // Get the value parsed by each arg.
    std::string name = nameArg.getValue();
    bool reverseName = reverseSwitch.getValue();

    // Do what you intend.
    if ( reverseName )
    {
            std::reverse(name.begin(),name.end());
            std::cout << "My name (spelled backwards) is: " << name << std::endl;
    }
    else
            std::cout << "My name is: " << name << std::endl;


    } catch (TCLAP::ArgException &e)  // catch any exceptions
    { std::cerr << "error: " << e.error() << " for arg " << e.argId() << std::endl; }
}
