MVC-如何从网址请求和保存pdf文件 [英] MVC - How to request and save a pdf file from a url
问题描述
我需要编写一个包含3个部分的api:
I need to program an api that has 3 parts:
- 从pdf网址获取pdf文件.
- 转换pdf.
- 返回转换后的pdf文件.
我已经完成了第2部分和第3部分， 剩下的就是从网址中获取pdf并将其复制/下载到我的mvc网络api中.
I have already completed part 2 and 3, What left is to fetch the pdf from url and copy/download it to my mvc web api.
这是测试html代码:
This is the test html code:
< script >
$('#btnSendRequest').on('click', function() {
$.ajax({
type: "POST",
url: "/Convertor/Html",
data: {
strUrl: "http://make-sense.co.il/kb/avcp-script-installation.pdf"
},
success: function(data) {
return true;
},
});
}); < /script>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<title>tester</title>
</head>
<body>
<h1>tester html</h1>
<div>
<input id="btnSendRequest" type="button" value="SendHttpRequest" />
</div>
我的ActionResult函数:"convertor/html"，从网页获取url字符串. 我需要的是，当我单击按钮时，pdf文件将自动下载到我的服务器上.
My ActionResult function: "convertor/html" , gets the url string from the web page. What I need is when I click the button, the pdf file will be automatically download to my server.
public ActionResult Html(string strUrl)
{
return View();
}
任何人都知道该怎么做? 我还读过有关base64编码的内容，这也许也是解决方案，但我以前从未使用过.
Anyone has any idea how that can be done? I also read somewhere on something called base64 encoding that might be also the solution, but I have never used it before.
谢谢.
推荐答案
您可能正在寻找的是.NET上的WebClient，请参见以下示例，我只是从示例中在线获取的，请参见
What you might be looking for is the WebClient on .NET, see the following example, I just grabbed it from an example online, see here for full article.
using System;
using System.Net;
using System.IO;
class Program
{
static void Main()
{
using (WebClient client = new WebClient())
{
// Download data.
byte[] arr = client.DownloadData("http://url-to-your-pdf-file.com/file1");
File.WriteAllBytes(path_to_your_app_data_folder, arr)
}
}
}
您将需要通过将byte []另存为文件进行进一步处理.上面的示例代码是针对控制台应用程序的，但是可以在mvc控制器中实现相同的代码.
you will need to do further processing by saving the byte[] as a file somewhere. the example code above is for a console app, but the same can be implemented in your mvc controller.
