使用express js在浏览器中显示Pdf [英] Display Pdf in browser using express js

问题描述

app.post('/asset', function(request, response){
  var tempFile="/home/applmgr/Desktop/123456.pdf";
  fs.readFile(tempFile, function (err,data){
     response.contentType("application/pdf");
     response.send(data);
  });
});

我是一个新的表达式，我不能发送与数据对象的响应。
二进制内容在浏览器中可见。
给我建议如何处理这个？

I am a new bie to expressjs, I can't send the response with the data object. The binary content is visible in the browser. Give me suggestions how to handle this ?

推荐答案

我测试了你的代码，它适用于我，更改：
将 app.post 更改为 app.get

I tested your code and it works for me in chrome with one change: Change app.post to app.get

编辑：由于您似乎认为仅POST服务器是个好主意，请阅读： http://net.tutsplus.com/tutorials/other/a-beginners-introduction-to-http-and-rest/
向下滚动直到HTTP动词，并查看GET和POST之间的区别。 ：）

since you seem to think a POST-only server is a good idea, read this: http://net.tutsplus.com/tutorials/other/a-beginners-introduction-to-http-and-rest/ Scroll down until the HTTP verbs and check out the difference between GET and POST. :)

一些快速研究表明，其他浏览器可能还有其他问题，例如IE可能希望URL以 .pdf 。因为我在我的Mac我无法为你测试;）

Some quick research suggests that other browsers might have other issues, IE for example might expect the URL to end in .pdf. Since I'm on my Mac I can't test that for you ;)
