1、sttok 修改源字符串 std::string str1 = str2; pch = strtok (str1.cstr()," ,.-"); 这样会修改str2的值...

解决办法:std::string str1 = str2.c_str(); 深拷贝字符串

#include <stdio.h>
#include <string.h>
int main ()
{
char str[] ="- This, a sample string.";
char * pch;
printf ("Splitting string \"%s\" into tokens:\n",str);
pch = strtok (str," ,.-");
while (pch != NULL)
{
    printf ("%s\n",pch);
    pch = strtok (NULL, " ,.-");
}
return 0;
}

2、C++字符串分割函数

void CApolloVoiceMgr::SplitStringIgnoreEmpty(const std::string& strSource, std::vector<std::string>& vecStr, const std::string& strDelimit)
{
std::string::size_type pos1, pos2;
pos2 = strSource.find_first_of(strDelimit);
pos1 = 0;
while(std::string::npos != pos2)
{
    if (pos2 - pos1 > 0)
    {
        vecStr.push_back(strSource.substr(pos1, pos2-pos1));
    }
    pos1 = pos2 + strDelimit.size();
    pos2 = strSource.find_first_of(strDelimit,pos1);
    }
    if(pos1 < strSource.length())
        vecStr.push_back(strSource.substr(pos1));
}
