chunked-encoding

问题 Background - I'm trying to stream an existing webpage to a separate web application, using HttpWebRequest/HttpWebResponse in C#. One issue I'm striking is that I'm trying to set the file upload request content-length using the file download's content-length, HOWEVER the issue seems to be when the source webpage is on a webserver for which the HttpWebResponse doesn't provide a content length. HttpWebRequest downloadRequest = WebRequest.Create(new Uri("downloaduri")) as HttpWebRequest; using

问题 I wanted to write a program to fetch tweets from Twitter and then do sentiment analysis. I wrote the following code and got the error even after importing all the necessary libraries. I'm relatively new to data science, so please help me. I could not understand the reason for this error: class TwitterClient(object): def __init__(self): # keys and tokens from the Twitter Dev Console consumer_key = 'XXXXXXXXX' consumer_secret = 'XXXXXXXXX' access_token = 'XXXXXXXXX' access_token_secret =

问题 I'm writing a streaming POST request handler in Tornado, using the @stream_request_body class decorator and implementing the data_received method to handle chunked data. I have some resources that I want to ensure are closed when the request has been serviced. If an error occurs within data_received , I can catch the exception, clean up resources and call send_error . But what happens if the connection is closed by the client? Does post get called in that case? 来源： https://stackoverflow.com

问题 I have to download file which HTTP response is "Transfer-Encoding: Chunked", because of what I can't to «getContentLength» to allocate new bytes buffer for DataInputStream. Can you advice me how to do it correctly? Code example is very simple: try { dCon = (HttpURLConnection) new URL(torrentFileDownloadLink.absUrl("href")).openConnection(); dCon.setRequestProperty("Cookie", "session=" + cookies.get("session")); dCon.setInstanceFollowRedirects(false); dCon.setRequestMethod("GET"); dCon

问题 I am currently writing a HTTP client to do a HTTP POST on a URL that returns a HTTP response. However, for error messages code 400 and 500, it sends back non chunked HTTP response, and for success messages, 201, it sends a chunked response. In the request, I am setting the content-length, so I am not sure why it is still sending us the chunked transfer encoding. Is there any other header I can set in the request, that will tell the HTTP server not to send chunked encoding? headerList.append(

问题 I would like to know how much data was sent in response to a certain http-request. What I currently do is this: HttpURLConnection con = (HttpURLConnection) feedurl.openConnection(); //check the response for the content-size int feedsize = con.getContentLength(); The problem is, that content-legnth is not always set. E.g. when the server uses transfer-encoding=chunked I get back a value of -1. I do not need this to display progress information. I just need to know the size of the data that was

问题 I wrote a client application that is suppose to download a file from a web server, very simple: using (WebClient webClient = new WebClient()) { webClient.DownloadFile("http://localhost/audiotest/audio.wav", @"C:\audio.wav"); } The web site (where audio file located: http://localhost/audiotest/audio.wav) has header Transfer-Encoding: chunked When I run the program, I get following error: The server committed a protocol violation. Section=ResponseBody Detail=Response chunk format is invalid How

问题 I need to send a POST request to a web server and be able to read the response sent by said server. I tried using the HTTPBuilder lib with this code : def http = new HTTPBuilder('http://myServer/') http.setProxy("Proxy_IP", 8080, "http") postBody = [cmd:'e',format:'sep',c:'a',b:'b',t:'u',r:'r',kl:'lop'] http.post( body: postBody, requestContentType: URLENC ){ resp -> HttpEntity he = resp.getEntity() println "${resp.getAllHeaders()}" println he.getContentType() println "${resp.getEntity()

问题 I have an application built on top of Spring MVC. I want to write simple proxy that processes requests as follows: send the same HTTP request to some specific server capture HTTP response from this specific server return the same answer to requesting client Here is what I've got so far: public void proxyRequest(HttpServletRequest request, HttpServletResponse response) { try { HttpUriRequest proxiedRequest = createHttpUriRequest(request); HttpResponse proxiedResponse = httpClient.execute

问题 I have an enormous file to upload and server on other side does support chunked upload. Is there any example of how exactly to do that? Or there is some other library which do that? 回答1: Using HttpClient 4 (From Apache) HttpPost post = new HttpPost(url); MultipartEntity content = new MultipartEntity(HttpMultipartMode.STRICT); //To add parameters, use StringBody content.addPart("param", new StringBody("value")); content.addPart("param1", new StringBody("value1")); content.addPart("param2", new
