I have the following function to download file.
let download url folder name =
use out = File.Create(Path.Combine(folder, name))
Http.RequestStream(url, cookieContainer = cc, headers = headers)
.ResponseStream.CopyTo(out)
However, I need another download function which just use the name from the website. How to get the name?
let download url folder =
let name = .... // get from the default name set by the website?
use out = File.Create(Path.Combine(folder, name))
Http.RequestStream(url, cookieContainer = cc, headers = headers)
.ResponseStream.CopyTo(out)

Currently, I can upload files(exist) with Grails's RestBuilder.
However, I want to upload a file without creating a file .
I want to create binary data (= Text File) in a program and send it directly
Is it possible?
RestBuilder rest = new RestBuilder()
RestResponse resp = rest.post(url){
contentType("multipart/form-data")
setProperty("dataFile",[filePath])// <- it can
setProperty("dataFile",[ byte[] or inputStream() or String ? ])// <- Is it possible?
}
'''
I'm sure you figured this out already, but you can just use a String reference or a byte[] just as you can use File instances for the multipart request using RestBuilder. It should 'just work' e.g.
RestBuilder rest = new RestBuilder()
RestResponse response = rest.post(url) {
contentType 'multipart/form-data'
stringPart = 'hello' // String
bytePart = '68656c6c6f'.decode64() // byte[]
filePart = new File('/path/to/file.jpg') // File
}
I have the following code:
var htmlToPdf = new NReco.PdfGenerator.HtmlToPdfConverter();
htmlToPdf.PdfToolPath = "~/files/";
htmlToPdf.GeneratePdf(template);
Which throws the following error:
Uri is not supported when saving pdf in server folder with nreco pdf generator.
You will need to set a regular path to your file system like e.g. "C:\temp\myfolder\". Or use a . instead of ~ and backslashes:
htmlToPdf.PdfToolPath = ".\\files\\";
If NReco is able to deliver you an byte-array or a stream you should prefer this instead of a file and return it directly.
UPDATE:
After takeing a look into the documentation of NReco all you need to do is following:
var htmlToPdf = new NReco.PdfGenerator.HtmlToPdfConverter();
htmlToPdf.PdfToolPath = "<CORRECT_PATH_FOR_TOOL>";
var output = htmlToPdf.GeneratePdf(template);
System.IO.File.WriteAllBytes("<OUTPUT_PATH>", output);
This should create your pdf in the OUTPUT_PATH.
#OlaFW thanx for your effort.
I got my answer.
var pdfBytes = htmlToPdf.GeneratePdf(template);
string filePath = "/files/Myfile.pdf";
string Url = System.Web.Hosting.HostingEnvironment.MapPath(filePath);
System.IO.File.WriteAllBytes(Url, pdfBytes);
I need to send the image file using multipart request from Lightroom to my local web service using Lua language.
I have tested using sending headers also but not working...
I have created a function :
function testupload(filepath) --created inside LrTasks
local url = "http://localhosturl"
local mycontent = {
{
name = "lightroom_message",
value = "sent from lightroom plugin multiparta"
},
{
name = 'file',
filePath = filepath,
fileName = LrPathUtils.leafName(filepath),
contentType = 'image/jpeg'
--contentType = 'multipart/form-data'
}
}
local response, headers = LrHttp.postMultipart(url, mycontent)
end
But my web service is not getting called properly and I am using LrHttp.postMultipart() method to do so..
If I am sending just this param to web service (then working fine):
{
name = "lightroom_message",
value = "sent from lightroom plugin multiparta"
}
but when I include my file payload then its not working using pure Lua implementation.
Everything was correct but just a technical mistake...I was trying to call the testupload() function from inside LRtasks..but we dont need to call it in separate task and the function works perfect
I want to download a file from an URL, the file name is updated frequently
For E.g.: filename_Date.zip where date changes.
Below is the Query I used
WebClient webClient = new WebClient();
webClient.DownloadFile("http://nppes.viva-it.com/NPPES_Deactivated_NPI_Report_081214.zip", #"C:\Users\gnanasem\Documents\NPIMatcher\NPI.zip");
Landing Page of the URL: http://nppes.viva-it.com/NPI_Files.html
Here you can see multiple files and I want to download the first one.
One way of doing this is to:
Get the HTML of the webpage
Find the URLs on the webpage using RegEx
Find the first URL containing the relevant text, in your case "Deactivated"
Download the file
I got it working like this:
using (var webClient = new WebClient())
{
var websiteHtml = webClient.DownloadString("http://nppes.viva-it.com/NPI_Files.html");
var urlPattern = "href\\s*=\\s*(?:[\"'](?<1>[^\"']*)[\"']|(?<1>\\S+))";
Match match = Regex.Match(websiteHtml, urlPattern, RegexOptions.IgnoreCase | RegexOptions.Compiled, TimeSpan.FromSeconds(1));
var urlToDownload = string.Empty;
while (match.Success)
{
var urlFound = match.Groups[1].Value;
if (urlFound.ToLower().Contains("deactivated"))
{
urlToDownload = urlFound;
break;
}
match = match.NextMatch();
}
webClient.DownloadFile(urlToDownload, #"C:\Users\gnanasem\Documents\NPIMatcher\NPI.zip");
}
Issue #1
When i'm uploading a file to google docs i receive status code "201" created, but when i try to open the file it seems that i'm doing something wrong, because i can't open it, and when i'm trying to download and open it on my PC i see the binary data instead of text or image. Current language is APEX, but i think it's pretty understandable.
First of all i'm getting Upload URL and then putting data to this URL;
public void getUploadURL()
{
Httprequest req = new Httprequest();
req.setEndpoint('https://docs.google.com/feeds/upload/create-session/default/private/full?convert=false');
req.setMethod('POST');
req.setHeader('GData-Version', '3.0');
req.setHeader('Authorization', 'OAuth '+accessToken);
req.setHeader('Content-Length', '359');
req.setHeader('X-Upload-Content-Type', fileType);
req.setHeader('X-Upload-Content-Length', fileSize);
Dom.Document requestDoc = new Dom.Document();
String xml =
'<?xml version=\'1.0\' encoding=\'UTF-8\'?>'
+'<entry xmlns="http://www.w3.org/2005/Atom" xmlns:docs="http://schemas.google.com/docs/2007">'
+'<title>'+fileName+'</title></entry>';
requestDoc.load(xml);
req.setBodyDocument(requestDoc);
Http h = new Http();
Httpresponse res = h.send(req);
System.debug('response=\n'+res.getHeader('Location'));
uploadFIle(res.getHeader('Location'));
}
public void uploadFIle(String uploadUrl)
{
Httprequest req = new Httprequest();
req.setEndpoint(uploadUrl);
req.setMethod('PUT');
req.setHeader('GData-Version', '3.0');
req.setHeader('Authorization', 'OAuth '+accessToken);
req.setHeader('Host', 'docs.google.com');
req.setHeader('Content-Length', fileSize);
req.setHeader('Content-Type', fileType);
req.setBody(''+binaryData);
Http h = new Http();
Httpresponse res = h.send(req);
System.debug('response=\n'+res.getBody());
}
As for "binaryData" property - i receive it from the page using javascript like this:
<input type="file" id="myuploadfield" onchange="getBinary()"/>
<script>
function getBinary()
{
var file = document.getElementById('myuploadfield').files[0];
fileSizeToController.val(file.size.toString());
fileNameToController.val(file.name.toString());
fileTypeToController.val(file.type.toString());
var r = new FileReader();
r.onload = function(){ binaryToController.val(r.result); };
r.readAsBinaryString(file);
}
</script>
r.onload = function(){ binaryToController.val(r.result); }; - this is the string that sends file binary data to my controller.
Issue #2
I'm trying to move one collection(folder) to another, and using this article (protocol tab instead of .NET). The issue is that i need to move collection instead of copying it and when i add my collection to another using this article, i'm currently adding reference to my collection instead of moving the whole collection from one place to another.
Please tell me what am i doing wrong.
Thank you for consideration.
Your "binary" data is being corrupted, when you are performing '' + binaryData.
In general, I have had more success using slicing of files, here is an example for webkit:
var chunk = this.file.webkitSlice(startByte, startByte + chunkSize, file_type);
// Upload the chunk
uploadChunk(startByte, chunk, callback);
