我怎样才能下载使用批处理文件的文件，而无需使用任何外部工具？下载使用、批处理文件、文件、工具
2023-09-02 10:20:23
作者：免贪
首先要澄清这个问题的目的是为HTTP（S）下载。对于FTP可能是我要问（并回答）另外一个问题。 这里是一些类似的问题 - 但我想更precise。
除了不包括外部工具，我想要的解决方案（S）是适用于最广泛的类型的Windows机器（包括XP，Win2003的，Vista中仍然有足够大的份额）。
另外，作为 WSH 是我preFER没有使用的临时文件，一切都将在一个蝙蝠文件（这是可能的两个JScript和VBScript）。
什么是可行的办法。
在纯批量解决方案的bitsadmin - 一个命令行工具 可每个Windows机器上。它不是pretty的方便，但是一个/唯一的选择在哪里 没有其他的脚本语言应该被使用。 使用WSH - 三种方法是可能的 - 的 WinHTTP的， MSXML2 .XMLHTTP ， InternetExlorer.Application - 所有的人可访问的ActiveX 为了我怎么preFER them.WinHTTP和MSXML2.XMLHTTP对象 是pretty的在自己的能力相似，但WinHTTP的有 更stable.InternetExlorer.Application声誉，其实是 只是互联网浏览器通过ActiveX对象访问， 一些UI元素是不可避免的（是吗？），所以我会跳过这一项。 在使用.NET - 它可以创建与所有的混合批处理文件 三个默认的.NET编译器（Jscript.net，VB.Net，C＃）与 Jscript.net没有多余的错误信息，所以我会preFER 它。如果我们忽略了一个事实，有一个编译的.exe所有code 是在一个文件中，因此按照我这个适合于要求:-) 。随着.NET我们可以使用System.Net.WebClient或 System.Net.HttpWebRequest（Web客户端依赖于它）或 System.Web.Htt prequest，但现在我只发布 System.Net.WebClient solution.And更相同的ActiveX对象 与WSH访问都可以在这里too.So真的有很多 途径dowanload与.Net.May的文件将在今后我会更新 我answer.Anyway只有Web客户端是专门为下载而设计的。 使用PowerShell的 - 具有相同的可能性，.NET，但少 机会要上，你可以meet.So我会跳过所有机器上安装 这一个了。 解决方案在answers.All脚本应保存蝙蝠 / .CMD 扩展，并且可以直接用作批处理脚本

First to clarify this question is aimed to HTTP(s) download .For FTP may be I'll ask (and answer) another question. Here are some similar questions - but I want to be more precise .
Besides excluding external tools I want the solution(s) to be applicable for the widest possible types of windows machines (including XP,Win2003,Vista which still have big enough share).
Also as WSH is one of the possible options I prefer no using of temp files and everything to be packed in a single .bat file (which is possible with both jscript and vbscript).
What are possible approaches.
"Pure" batch solution with BITSADMIN - a command line utility available on every windows machine .It's not pretty convenient but is an/the only option where no other scripting language should be used. Using WSH - Three approaches are possible - WinHTTP , MSXML2.XMLHTTP ,InternetExlorer.Application - all of them are accessible ActiveX objects in order of how I prefer them.WinHTTP and MSXML2.XMLHTTP are pretty similar in their capabilities but WinHTTP has a reputation of more stable.InternetExlorer.Application is in fact just the Internet explorer accessible through ActiveX object and some UI elements are unavoidable (are they?) so I'll skip this one. Using .NET - It's possible to create a hybrid batch file with all the three default .NET compilers (Jscript.net , VB.Net , C#) with Jscript.net there is no redundant error messages so I'll prefer it.If we ignore the fact that there's a compiled .exe all the code is in one file ,so according to me this fits in the requirements :-) .With .NET we can use System.Net.WebClient or System.Net.HttpWebRequest (the WebClient relies on it) or System.Web.HttpRequest , but for now I'll post only System.Net.WebClient solution.And even more same ActiveX objects accessible with WSH are available here too.So there are really many ways to dowanload a file with .Net.May be in the future I'll update my answer.Anyway only the Webclient is especially designed for download. Using powershell - has same possibilities as .NET but with less chances to be installed on all machines you can meet.So I'll skip this one too.解决方案
The answers.All scripts should be saved with .bat/.cmd extensions and can be used directly as batch scripts.
