Question

I am writing a simple python server and using do_GET to return a html by following

from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler

class RequestHandler(BaseHTTPRequestHandler):
   def _writeheaders(self):
       self.send_response(200)
       self.send_header('Content-type', 'text/html')
       self.end_headers()

   def do_HEAD(self):
       self._writeheaders()

   def do_GET(self):
       f = open("/full/path/to.html")
       self._writeheaders()
       self.wfile.write(f.read())


serveraddr = ('localhost', 7070)
srvr = HTTPServer(serveraddr, RequestHandler)
srvr.serve_forever()

in the html a have

<html>
<head>
    <title>myChart</title>
    <meta charset="UTF-8">
</head>

<div >
    ...divs...
</div>


<script>

...js functions...

</script>

<body>

<script src="js/jquery-1.8.2.min.js" type="text/javascript"></script>


</body>
</html>

I was able to get the html, however in the browser console says Uncaught SyntaxError: Unexpected token < at jquery-1.8.2.min.js:1

If I directly open html page in browser, everything is fine so the problem is not in the html

----update----

I was using Chrome and by clicking the error in the console, the source showed up was the html itself instead of the js file. I tried to specify the full path of the js file in the html, however it still showed me the html file in the error

There js file works fine when I open the html file by enter it dir in the browser

Also in the python console I can see:

127.0.0.1 - - [28/Jun/2015 00:12:28] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [28/Jun/2015 00:12:28] "GET /full/path/to/js/jquery-1.8.2.min.js HTTP/1.1" 200 -
127.0.0.1 - - [28/Jun/2015 00:12:28] "GET /favicon.ico HTTP/1.1" 200 -

Answer 1

您的RequestHandler将提供您的HTML网页，无论网址是什么 - 该网址是/，/index.html，/favicon.ico还是（在您的情况下）{{ 1}}。如果您希望/js/jquery-1.8.2.min.js再次提供实际的JavaScript文件而非HTML页面，则需要特别处理，例如：

/js/jquery-1.8.2.min.js

您可能希望稍微更改一下，以便请求JavaScript文件提供适当的def do_GET(self): if self.path == '/js/jquery-1.8.2.min.js': filename = 'js/jquery-1.8.2.min.js' else: filename = 'index.html' with open(filename, 'r') as f: self._writeheaders() self.wfile.write(f.read())标头而不是Content-Type: text/javascript，Content-Type: text/html返回与{HEAD一致的标头1}}等等。

此外，如果您开始提供大型文件，您可能需要考虑使用shutil.copyfileobj将文件中的数据复制到GET，而不是将整个文件读入内存并进行编写全力以赴。
