int argc = 0;
    char** argv = (char **) malloc(30 * sizeof(char *));
    char *token = NULL;
    const char* delim = ",";
    const char* str = "MyExe,-u,zyg,-p,123456,192.168.31.188";
    char *params = malloc(strlen(str)+1);
    memcpy(params, str, strlen(str)+1);
    token = strtok(params, delim);
    int index = 0;
    while(token != NULL)
    {
        int length = strlen(token)+1;
        argv[index] = (char *)malloc(length);
        memcpy(argv[index],token,length);
        index++;
        token = strtok(NULL, delim);
    }
    argc = index;

    int i=0;
    for(;i<index;i++){
        printf("argv[%d]=%s\n",i,argv[i]);
    }
    printf("\n");

                                输出结果
argv[0]=MyExe
argv[1]=-u
argv[2]=zyg
argv[3]=-p
argv[4]=123456
argv[5]=192.168.31.188
