I have written the code for downloading a pdf file over http request.
public void downloadDocument(HttpServletRequest request,
HttpServletResponse response, #PathVariable("id") String docId)
throws Exception {
HttpSession session = request.getSession(true);
int accountId = (Integer) session.getAttribute("ownerAccountId");
Map<String, String> docMap = DbInteractor.getUploadedDocsByDocId(
Integer.valueOf(docId), accountId);
String docName = docMap.get("name");
String typeName = docMap.get("type");
String[] fileName = docName.split("\\.(?=[^\\.]+$)");
typeName= typeName.replace(" ", "");
if (typeName.equals("CCD/CCR")) {
typeName = "CCDorCCR";
}
String filename = typeName + docId + "." + fileName[1];
System.out.println(filename);
FileInputStream fileInputStream = new FileInputStream(
Constants.DOCUMENTS_PATH + filename);
response.setHeader("Expires", "0");
response.setHeader("Cache-Control",
"must-revalidate, post-check=0, pre-check=0");
response.setHeader("Content-disposition", "attachment; filename="
+ docName);
OutputStream os = response.getOutputStream();
IOUtils.copy(fileInputStream, os);
os.flush();
os.close();
}
But the file is getting automatically downloaded in chrome .Is there any way to force chrome to open this document in a viewer(or to ask for an open with dialog in chrome)
You are forcing the browser to download by sending "Content-Disposition: attachment".

I have an http POST being actioned via a .NET System.Net.WebRequest as follows:
...
XXXUtilities.Log.WriteLog(string.Format("XXXHTTPPost PostToUri has uri={0}, body={1}", uri, messageBodyAsString));
System.Net.WebRequest req = System.Net.WebRequest.Create(uri);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(messageBodyAsString);
req.ContentLength = bytes.Length;
System.IO.Stream os = req.GetRequestStream();
os.Write(bytes, 0, bytes.Length);
os.Close();
try
{
using (System.Net.WebResponse resp = req.GetResponse())
{
if (resp == null) return null;
System.IO.StreamReader sr =
new System.IO.StreamReader(resp.GetResponseStream());
string rs = sr.ReadToEnd().Trim();
sr.Close();
resp.Close();
XXXUtilities.Log.WriteLog(string.Format("XXXHTTPPost PostToUri has string response = {0}", rs));
MongoDB.Bson.BsonDocument doc2 = new BsonDocument();
doc2.Add("Response", rs);
return doc2;
}
}
catch (System.Net.WebException e)
{...
This all works fine most of the time. However, looking at the log files that this creates I spotted something strange. The suspect log entries look like this:
18:59:17.0608 HPSHTTPPost PostToUri has uri=https://salesforce.ringlead.com/cgi-bin/2848/3/dedup.pl, body=LastName=Doe&FirstName=Jon
18:59:17.5608 HPSHTTPPost PostToUri has string response = Success
18:59:18.0295 HPSHTTPPost PostToUri has string response = Success
It seems that the Http Response is being received twice. Is this even technically possible? i.e. is it possible for an Http POST to receive two Responses, one after the other? If so, is my code below then liable to be called twice, thus resulting in the observed log file entries? Many thanks.
Edit:
In response to the comment that the logging code may be broken, here is the logging code:
public class Log
{
public static void WriteLog(string commandText)
{
string clientDBName = "test";
string username = "test";
try
{
string filePath = "c:\\Data\\XXXLogs\\" + clientDBName + "logs\\";
string filename = System.DateTime.Now.ToString("yyyyMMdd_") + username + ".log";
DirectoryInfo dir = new DirectoryInfo(filePath);
if (!dir.Exists)
{
dir.Create();
}
System.IO.FileStream stream = new System.IO.FileStream(
filePath + filename
, System.IO.FileMode.Append); // Will create if not already exists
StreamWriter writer = new StreamWriter(stream);
writer.WriteLine(); // Writes a line terminator, thus separating entries by 1 blank line
writer.WriteLine(System.DateTime.Now.ToString("HH:mm:ss.ffff") + " " + commandText);
writer.Flush();
stream.Close();
}
catch { }
}
}
String filePath = "http://images.all-free-download.com/images

url.openConnection();

String relativePath = getServletContext().getRealPath("");
// obtains ServletContext
ServletContext context = getServletContext();
// gets MIME type of the file
String mimeType = context.getMimeType(filePath);
if (mimeType == null) {
// set to binary type if MIME mapping not found
mimeType = "application/octet-stream";
}
// modifies response
response.setContentType(mimeType);
response.setContentLength((int) httpConn.getContentLength());
String fileName = filePath.substring(filePath.lastIndexOf("/") +
1,
filePath.length());
// forces download
//String headerKey = "Content-Disposition";
//String headerValue = String.format("attachment;

response.setHeader("Content-Transfer-Encoding", "binary");
response.setHeader("Content-Disposition","attachment;
filename=\""+ fileName);
//response.setHeader(headerKey, headerValue);
// obtains response's output stream
OutputStream outStream = response.getOutputStream();
byte[] buffer = new byte[4096];
int bytesRead = -1;
while ((bytesRead = inStream.read(buffer)) != -1) {
outStream.write(buffer, 0, bytesRead);
}
inStream.close();
outStream.close();

All files that come from DocuSign are going to be .PDF files.
Your documents will be saved as the name they were uploaded as (often contain the extension). So if you're writing the file with the name that it is stored in DocuSign by DocumentPDF->Name. I would do a .Replace and replace the extension with .pdf.
I'm trying to set up a web api service that searches for a .pdf file in a directory and returns the file if it's found.
The controller
public class ProductsController : ApiController
{
[HttpPost]
public HttpResponseMessage Post([FromBody]string certificateId)
{
string fileName = certificateId + ".pdf";
var path = #"C:\Certificates\20487A" + fileName;
//check the directory for pdf matching the certid
if (File.Exists(path))
{
//if there is a match then return the file
HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
var stream = new FileStream(path, FileMode.Open);
stream.Position = 0;
result.Content = new StreamContent(stream);
result.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment") { FileName = fileName };
result.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");
result.Content.Headers.ContentDisposition.FileName = fileName;
return result;
}
else
{
HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.Gone);
return result;
}
}
}
I'm calling the service with the following code
private void GetCertQueryResponse(string url, string serial)
{
string encodedParameters = "certificateId=" + serial.Replace(" ", "");
HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create(url);
httpRequest.Method = "POST";
httpRequest.ContentType = "application/x-www-form-urlencoded";
httpRequest.AllowAutoRedirect = false;
byte[] bytedata = Encoding.UTF8.GetBytes(encodedParameters);
httpRequest.ContentLength = bytedata.Length;
Stream requestStream = httpRequest.GetRequestStream();
requestStream.Write(bytedata, 0, bytedata.Length);
requestStream.Close();
HttpWebResponse response = (HttpWebResponse)httpRequest.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
byte[] bytes = null;
using (Stream stream = response.GetResponseStream())
using (MemoryStream ms = new MemoryStream())
{
int count = 0;
do
{
byte[] buf = new byte[1024];
count = stream.Read(buf, 0, 1024);
ms.Write(buf, 0, count);
} while (stream.CanRead && count > 0);
ms.Position = 0;
bytes = ms.ToArray();
}
var filename = serial + ".pdf";
Response.ContentType = "application/pdf";
Response.Headers.Add("Content-Disposition", "attachment; filename=\"" + filename + "\"");
Response.BinaryWrite(bytes);
}
}
This appears to be working in the sense that the download file dialogue is shown with the correct file name and size etc, but the download takes only a couple of seconds (when the file sizes are >30mb) and the files are corrupt when I try to open them.
Any ideas what I'm doing wrong?
Your code looks similar to what Ive used in the past, but below is what I typically use:
Response.AddHeader("content-length", myfile.Length.ToString())
Response.AddHeader("content-disposition", "inline; filename=MyFilename")
Response.AddHeader("Expires", "0")
Response.AddHeader("Pragma", "Cache")
Response.AddHeader("Cache-Control", "private")
Response.ContentType = "application/pdf"
Response.BinaryWrite(finalForm)
I post this for 2 reasons. One, add the content-length header, you may have to indicate how large the file is so the application waits for the whole response.
If that doesn't fix it. Set a breakpoint, does the byte array content the appropriate length (aka, 30 million bytes for a 30 MB file)? Have you used fiddler to see how much content is coming back over the HTTP call?
I can upload file to google drive from my website, but my problem is it will show the file as Untitled after uploading.
How can I add or post title to the uploading file.
Thanks,
My Code:

{
try
{
string result = "";
byte[] buffer = file_data;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.googleapis.com/upload/drive/v2/files?uploadType=media");
request.Method = "POST";
request.ContentType = mime_type;
request.ContentLength = buffer.Length;
request.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + accessToken);
var stream = request.GetRequestStream();
stream.Write(file_data, 0, file_data.Length);
stream.Close();
HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();//Get error here
if(webResponse.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = webResponse.GetResponseStream();
StreamReader responseStreamReader = new StreamReader(responseStream);
result = responseStreamReader.ReadToEnd();//parse token from result
var jLinq = JObject.Parse(result);
JObject jObject = JObject.Parse(jLinq.ToString());
webResponse.Close();
return jObject["alternateLink"].ToString();
}
return string.Empty;
}
catch
{

I used RestSharp for uploading a file to google drive.
public static void UploadFile(string accessToken, string parentId)
{
var client = new RestClient { BaseUrl = new Uri("https://www.googleapis.com/") };
var request = new RestRequest(string.Format("/upload/drive/v2/files?uploadType=multipart&access_token={0}", accessToken), Method.POST);
var bytes = File.ReadAllBytes(#"D:\mypdf.pdf");
var content = new { title = "mypdf.pdf", description = "mypdf.pdf", parents = new[] { new { id = parentId } }, mimeType = "application/pdf" };
var data = JsonConvert.SerializeObject(content);
request.AddFile("content", Encoding.UTF8.GetBytes(data), "content", "application/json; charset=utf-8");
request.AddFile("mypdf.pdf", bytes, "mypdf.pdf", "application/pdf");
var response = client.Execute(request);
if (response.StatusCode != HttpStatusCode.OK) throw new Exception("Unable to upload file to google drive");
}
Doing it with out using the google.apis dlls isnt that easy. You need to send the meta data before you send the rest of the file. For that you need to use uploadType=multipart

This should get you started sorry its a wall of code. I havent had time to create a tutorial for this yet.
FileInfo info = new FileInfo(pFilename);
//Createing the MetaData to send
List<string> _postData = new List<string>();
_postData.Add("{");
_postData.Add("\"title\": \"" + info.Name + "\",");
_postData.Add("\"description\": \"Uploaded with SendToGoogleDrive\",");
_postData.Add("\"parents\": [{\"id\":\"" + pFolder + "\"}],");
_postData.Add("\"mimeType\": \"" + GetMimeType(pFilename).ToString() + "\"");
_postData.Add("}");
string postData = string.Join(" ", _postData.ToArray());
byte[] MetaDataByteArray = Encoding.UTF8.GetBytes(postData);
// creating the Data For the file
byte[] FileByteArray = System.IO.File.ReadAllBytes(pFilename);
string boundry = "foo_bar_baz";
string url = "https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart" + "&access_token=" + myAutentication.accessToken;
WebRequest request = WebRequest.Create(url);
request.Method = "POST";
request.ContentType = "multipart/related; boundary=\"" + boundry + "\"";
// Wrighting Meta Data
string headerJson = string.Format("--{0}\r\nContent-Type: {1}\r\n\r\n",
boundry,
"application/json; charset=UTF-8");
string headerFile = string.Format("\r\n--{0}\r\nContent-Type: {1}\r\n\r\n",
boundry,
GetMimeType(pFilename).ToString());
string footer = "\r\n--" + boundry + "--\r\n";
int headerLenght = headerJson.Length + headerFile.Length + footer.Length;
request.ContentLength = MetaDataByteArray.Length + FileByteArray.Length + headerLenght;
Stream dataStream = request.GetRequestStream();
dataStream.Write(Encoding.UTF8.GetBytes(headerJson), 0, Encoding.UTF8.GetByteCount(headerJson)); // write the MetaData ContentType
dataStream.Write(MetaDataByteArray, 0, MetaDataByteArray.Length); // write the MetaData
dataStream.Write(Encoding.UTF8.GetBytes(headerFile), 0, Encoding.UTF8.GetByteCount(headerFile)); // write the File ContentType
dataStream.Write(FileByteArray, 0, FileByteArray.Length); // write the file
// Add the end of the request. Start with a newline
dataStream.Write(Encoding.UTF8.GetBytes(footer), 0, Encoding.UTF8.GetByteCount(footer));
dataStream.Close();
try
{
WebResponse response = request.GetResponse();
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
//Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
}
catch (Exception ex)

return "Exception uploading file: uploading file." + ex.Message;

If you need any explinations beyond the comments let me know. I strugled to get this working for a month. Its almost as bad as resumable upload.
I was searching for the solution of the given problem and previously I was putting uploadType=resumable that causes the given issue and when I used uploadType=multipart problem is resolved...
