测试登录密码修改，网页没保存

coobeebingb

我就 修改下登录用户admin的密码，只此一个用户，密码可存的。嵌入式，目标机存储密码（存储方式未知）。
参数化了，原参数 pwd_origin仅设一值,pwd_now也只设一值；每次都把新值写到原值的参数化文件中，以便下次迭代的密码更新；回放完脚本后，迭代2次，模式是sequential/each iteration。跑完，重新登录，密码还是pwd_origin最初的那个值。？？？？？？？

代码 啰嗦如下，请大虾指教：

web_set_sysuser()
{
        long outfread;//A FILE pointer for reading from .dat file
        long outfwrite;///A FILE pointer for writing to .dat file

        int i =10;

        unsigned long status = strlen("{pwd_origin}");
        char ch = 'h';//for func:lr_eval_string_ext
        const char *file = &ch;//for func:lr_eval_string_ext

        char ** const out_str_origin = (char **)malloc(status);//for func:lr_eval_string_ext
        char ** const out_str_now = (char **)malloc(status);//for func:lr_eval_string_ext
        unsigned long * const out_len = &(status);//for func:lr_eval_string_ext

        //replace password decrypted function lr_decrypt with
        //C variable(out_str_origin) that received the value of password parameter
                  //lr_eval_string_ext("{pwd_origin}", status, out_str_origin, out_len, 0, file, -1);
                  //lr_output_message("!!!!!!!!!!!!current pwd to log---------%s", *out_str_origin);

        outfread = fopen("pwd_origin.dat","r");         

    if( outfread )
    {
                fseek( outfread, strlen("pwd_origin") + 1, 0 );//指针指向从文件头开始跳过“pwd_origin”所含字节数
                //write new value to pwd_origin file, in order to change parameter value
                fscanf(outfread, "%s", *out_str_origin);

期待 回复。。。。

谢谢 楼上。我正是因为 为了看具体值才打印的。第二次 迭代老是 pwd_origin最初的值。
