通过将命令馈送到JScript中的StdIn来编写WinSCP脚本-脚本挂起并且永远不会完成

winscp jscript wsh sftp io

Arman Avetisyan · 技术社区 · 7 年前

我正在尝试从SFTP服务器下载大约40个文件,但它只下载了其中的30个文件并挂起。
请帮忙解决这个问题。

这是我正在使用的脚本。

var exec = shell.Exec("winscp.com /xmllog=\"C:\\download\\log\\download.xml\" "); 
exec.StdIn.Write( 
    "option batch abort\n"+ 
    "option confirm off\n"+ 
    "open sftp://xxx:xxx@xxx -hostkey=\"xxxx\" \n"+ 
    "get /download/* \"C:\\download\\\" \n"+ 
    "exit");

请参阅下面的日志。
我在日志文件中找不到任何问题:

这是添加“var output=exec.StdOut.ReadAll();”后的完整工作代码

var exec = shell.Exec("winscp.com /log=\"C:\\log\\download.log\" ");
exec.StdIn.Write(
    "option batch abort\n"+
    "option confirm off\n"+
    "open sftp://xxx:xxx@xxx  -hostkey=\"xxx\" \n"+
    "get -delete /compliance/* \"C:\\compliance\\\"  \n"+
    "exit");

exec.StdIn.Close();
var output = exec.StdOut.ReadAll();

谢谢

你没有告诉我们你在比赛后做了什么 exec.StdIn.Write() .

确保您阅读了程序输出,例如这样(作为官方 JScript example for Access to Input/Output streams )显示:

var output = exec.StdOut.ReadAll();

另请参见 Capturing outputs of WinSCP process

您需要在脚本运行时连续收集输出。输出流的容量有限。一旦填满,WinSCP就会挂起等待可用空间,永远不会结束。

除此之外,您还必须终止 exit 带的命令 \n . 尽管在您的情况下,使用标准输入提供命令没有多大意义。只需使用 /command switch on WinSCP command-line .
