通过向WinSCP中的StdIn提供命令来编写JScript脚本--脚本挂起并且永远不会完成
通过向WinSCP中的StdIn提供命令来编写JScript脚本--脚本挂起并且永远不会完成
提问于 2017-10-17 21:44:41
我试图从SFTP服务器下载大约40个文件，而它只下载了30个文件并挂起。
请帮助解决这个问题。
这就是我要用的剧本。
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"); 请看下面的日志。
我在日志文件中找不到任何问题：

你没有向我们展示，你在exec.StdIn.Write()之后做了什么。
确保读取程序输出，例如如下所示(如官方访问输入/输出流的JScript示例所示)：
var output = exec.StdOut.ReadAll();还请参见捕获WinSCP过程的输出 (同样的问题，但对于C#)：
在脚本运行时，需要不断地收集输出。输出流容量有限。一旦它被填满，WinSCP就会挂起等待空闲的空间，永远不会结束。
此外，您还必须使用exit终止\n命令。尽管在您的示例中，使用标准输入提供命令没有多大意义。只需使用打开WinSCP命令行。
