问题 I copied a code piece to send files to browser. I don't know why we use the lines written below cause removing these does not make any difference in my development environment. Response.Clear(); Response.ClearHeaders(); Response.Buffer = false; Can anyone provide a simple break down of the intended purpose & appropriateness of these. Thanks 回答1: Response.Clear(); If you have written anything out already to the buffer, you'll need to clear that so extraneous content doesn't get included.

问题 I use Python Rquests to extract full headers of responses. I want to accurately count how many cookies (i.e. nam/variable) pairs in a response. There are two issues: 1) If a server responded with multiple Set-Cookie headers. How does Requests represent this? Does it combine both Set-Cookie values in one? Or leave it as is? Here is my script to print headers (full header): import requests requests.packages.urllib3.disable_warnings() # to disable certificate warnings response = requests.get(

问题 I'm doing a restfull api in cakephp... And sometime i have some throw exceptions. For example: if (!$this->request->is('post')) { throw new MethodNotAllowedException("The requested resource does not support http method " . $this->request->param('_method')); } My problem is when the url is /controller/action.json the response is : { message: "The requested resource does not support http method GET", url: "/api/auth/users/authenticate.json", code: 405 } In json format, but, when my url is

问题 I have a task to pass huge JSON response and would like to understand what is the best practice for that. What I'm doing right now is using StreamHttpResponse : def generator_chunk(): ... yield df.to_json # returns data like [json] @api_view(['GET']) def return_data(request): ... return StreamHttpResponse(generator_chunk) # streams data like [json][json], which is not proper json format Few options I have right now on how to solve it: Create temp file and store all chunks there - then stream

问题 I have an HttpResponse containing some data (json/xml, which can contain a large amount of data). I am using a function that reads and uses an input stream with this data (which is closed, and cannot be changed either than maybe accepting a string instead of an inputstream), and a different function that validates the data (general validation, not related to the actual usage which is a part I can't touch). I would like to do something like this: HttpResponse response = getTheResponse();

问题 I have a M2M project that sends out the following headers. HTTP/1.1 Accept-Language: zh-cn Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) Host: xxx.xxx.xxx.xxx:xxxx RANGE:bytes=0-1023 Connection: Keep-Alive Apache and ISS have connection : close in the response headers, regardless of the request to keep-alive . Lighttpd I assume is actually performing correctly as it does keep the connection alive, or does not send a connection : close . I
