Python 窗口上的卷曲精度
在windows中,pycurl将计时精度提高到小数点后3位,是否有方法将其提高到更精确的程度Python 窗口上的卷曲精度,python,windows,curl,libcurl,Python,Windows,Curl,Libcurl,在windows中,pycurl将计时精度提高到小数点后3位,是否有方法将其提高到更精确的程度 > print c.getinfo(pycurl.CONNECT_TIME) > 0.265 例如,Linux将其设置为大约7位小数。查看pycurl的源代码,它只是调用底层的cURL函数: case CURLINFO_CONNECT_TIME: // other cases [snip]ped /* Return PyFloat as result */
> print c.getinfo(pycurl.CONNECT_TIME)
> 0.265
例如,Linux将其设置为大约7位小数。查看pycurl的源代码,它只是调用底层的cURL函数:
case CURLINFO_CONNECT_TIME: // other cases [snip]ped
/* Return PyFloat as result */
double d_res = 0.0;
res = curl_easy_getinfo(self->handle, (CURLINFO)option, &d_res);
if (res != CURLE_OK) {
CURLERROR_RETVAL();
}
return PyFloat_FromDouble(d_res);
}
而这反过来又起作用
case CURLINFO_CONNECT_TIME:
*param_doublep = data->progress.t_connect;
break;
而t_connect
由
data->progress.t_connect = Curl_tvdiff_secs(now, data->progress.t_startsingle);
它引用了由定义为
struct timeval curlx_tvnow(void)
{
/*
** GetTickCount() is available on _all_ Windows versions from W95 up
** to nowadays. Returns milliseconds elapsed since last system boot,
** increases monotonically and wraps once 49.7 days have elapsed.
*/
struct timeval now;
DWORD milliseconds = GetTickCount();
now.tv_sec = milliseconds / 1000;
now.tv_usec = (milliseconds % 1000) * 1000;
return now;
}
也就是说,毫秒精度
这么短的补丁和重新编译cURL使用更高精度的计时器,然后编译pyCURL对这一点,不。对不起 查看pycurl的源代码,它只是调用底层的cURL函数:
