发送指定网址的静态文件 [英] Send a static file for a specifed URL

问题描述

我当前正在使用解析来部署我的Web应用程序.我正在使用Express将URL路由到适当的内容.

I am currently using parse to deploy my web app. I am using Express to route the url to the appropriate content.

当前，我尝试为以下网址提供index.html；

Currently I trying to serve index.html for the following url;

mystackoverflowapp.parseapp.com/hi

在我的云代码中，我具有以下请求处理程序

In my cloud code I have the following request handler

app.get('/hi', function(req, res){
  res.sendFile('index.html');
});

根据分析文档，默认目录为公共目录.不幸的是，此请求处理程序不起作用.当我转到stackoverflow.parseapp.com时，出现500错误内部服务器错误".

According to the parse documentation the default directory is the public directory. Unfortunately this request handler does not work. When I go to my stackoverflow.parseapp.com I get a 500 error, "Internal Server Error".

我正在遵循与文档中概述的相同的目录结构，并尝试在每个目录中都包含index.html文件.

I am following the same directory structure as outlined in the documentation and have tried having the index.html file in every directory.

如果我尝试

res.send('This works!') 

对于相同的路线，我得到了预期的响应，

for the same route I get the expected response,

"This works!". 

对我在做什么错有任何想法吗?另外，对此进行更好的调试的最佳方法是什么? 500错误并不能说明太多.

Any thoughts on what I am doing wrong? Also, what's the best way to get better debugging on this? A 500 error doesn't really reveal too much.

推荐答案

来自 http: //expressjs.com/4x/api.html#res.sendFile :

除非在options对象中设置了root选项，否则path必须是 文件的绝对路径.

Unless the root option is set in the options object, path must be an absolute path of the file.

更新1:我尝试过:

app.get('/test', function(req,res) {
    try {
        res.sendFile('test.html');
    } catch (err) {
        res.send('ERROR ' + err);
    }
});

它产生:

错误TypeError:对象[object Object]没有方法'sendFile'

ERROR TypeError: Object [object Object] has no method 'sendFile'

然后我偶然发现了以下内容:如何在Parse上手动提供文件.com?.相关报价:

I then stumbled across this: How to manually serve files on Parse.com?. The relevant quote:

...似乎Parse运行Node模块的自定义子集.他们已删除 所有文件系统方法. Express API上没有sendFile()，没有 fs模块上的readFile()...

...it seems Parse runs a custom subset of Node modules. They've erased all filesystem methods. There's no sendFile() on Express API, no readFile() on fs module...

更新2:

Parse为您的应用程序设置了一个静态文件处理程序，因此请尝试以下操作:

Parse sets up a static file handler for your app, so try this:

app.get('/hi', function(req, res){
  res.redirect('/index.html');
});
