I have one Lotus DB (db1) on one server and second lotus db (db2) on another server.
How can I receive data from db1 to db2 via REST service (REST is configured in db1 to receive data from view in db1)?
I think the task must be clear, but I can't find a simple solution to this task :(
Use REST service's property databaseName with !! between server and database path:
<xe:restService id="restService2" pathInfo=...>
<xe:this.service>
<xe:viewItemFileService
databaseName="Server01!!Test/db1.nsf"
viewName="viewInDb1"
...>
</xe:viewItemFileService>
</xe:this.service>
</xe:restService>
You can call the URL:
var host = facesContext.getExternalContext().getRequest().getHeader("Host");
var path = facesContext.getExternalContext().getRequest().getContextPath();
var page = "/RESTServiceProvider.xsp/hotSheets?rName=AarionPerez";
var url = "http://" + host + path + page;
var url:java.net.URL = new java.net.URL(url);
var urlconn:java.net.URLConnection = url.openConnection();
var reader:java.io.BufferedReader = new java.io.BufferedReader(new java.io.InputStreamReader(urlconn.getInputStream()));
var inputLine;
var inJson = "";
while ((inputLine = reader.readLine()) != null){
inJson += inputLine;
}
reader.close();
This is a call from a NSF, but you can put a non-NSF URL in and get a response. You may need to pass in authentication as well.

I am able to programmatically log in to the PowerBI Client, gather my Workspaces as well as get a specific Report from a specific Workspace. I need to programmatically render that report to a .pdf or .xlsx file. Allegedly this is possible with the ExportToFileInGroup/ExportToFileInGroupAsync methods. I even created a very simple report without any parameters. I can embed this using the sample app from here. So that at least tells me that I have what I need setup in the backend. But it fails when I try to run the ExportToFileInGroupAsync method (errors below code.)
My Code is:
var accessToken = await tokenAcquisition.GetAccessTokenForUserAsync(new string[] {
PowerBiScopes.ReadReport,
PowerBiScopes.ReadDataset,
});
var userInfo = await graphServiceClient.Me.Request().GetAsync();
var userName = userInfo.Mail;
AuthDetails authDetails = new AuthDetails {
UserName = userName,
AccessToken = accessToken,
};
var credentials = new TokenCredentials($"{accessToken}", "Bearer");
PowerBIClient powerBIClient = new PowerBIClient(credentials);
var groups = await powerBIClient.Groups.GetGroupsAsync();
var theGroup = groups.Value
.Where(x => x.Name == "SWIFT Application Development")
.FirstOrDefault();
var groupReports = await powerBIClient.Reports.GetReportsAsync(theGroup.Id);
var theReport = groupReports.Value
.Where(x => x.Name == "No Param Test")
.FirstOrDefault();
var exportRequest = new ExportReportRequest {
Format = FileFormat.PDF,
};
string result = "";
try {
var response = await powerBIClient.Reports.ExportToFileInGroupAsync(theGroup.Id, theReport.Id, exportRequest);
result = response.ReportId.ToString();
} catch (Exception e) {
result = e.Message;
}
return result;
It gets to the line in the try block and then throws the following errors:
An error occurred while sending the request.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host..
UPDATE
Relating to #AndreyNikolov question, here is our Embedded capacity:
After this was implemented, no change. Same exact error.
Turns out the issue was on our side, more specifically, security/firewall settings. Here is the exact quote from our networking guru.
"After some more investigation we determined that our firewall was causing this issue when it was terminating the SSL connection. We were able to add a bypass for the URL and it is now working as expected."
I'm currently trying to use the Rest APIs exposed by Visual Studio Team Services (was Visual Studio Online) to obtain work item information. I seem to be able to connect however when I look at the response to my query its a html page with a Enhanced Security Error message. I believe that this is due to the Enhanced Security option in IE but I'm calling this from my client machine and I can only see options on how to turn this off on a server.
this is the call i'm making
using (var client = new HttpClient())
{
var token = "xxxxxxxxxxxx";
var apiVersion = "1.0";
var account = "xxxxxxxx";
var query = "Select [System.Id] From WorkItems Where[System.WorkItemType] = 'WorkItem' order by [System.CreatedDate] desc";
var url = "https://" + account + ".visualstudio.com/Core/_apis/wit/";
// Execute a query that returns work item IDs matching the specified criteria
using (var request = new HttpRequestMessage(HttpMethod.Post, url + "wiql"))
{
request.Headers.Add("Authorization", "Bearer " + token);
request.Headers.Add("Accept", "application/json;api-version=" + apiVersion);
Dictionary<string, string> body = new Dictionary<string, string>
{
{
"query", query
}
};
request.Content = new StringContent(JsonConvert.SerializeObject(body), Encoding.UTF8, "application/json");
using (var response = await client.SendAsync(request))
{
var content = await response.Content.ReadAsStringAsync();
var workItems = JObject.Parse(content)["workItems"] as JArray;
string[] ids = workItems.Select<JToken, string>(w => (w["id"] + "")).Take(10).ToArray<string>();
string idsString = String.Join(",", ids);
// Get details for the last 10
using (var detailsRequest = new HttpRequestMessage(HttpMethod.Get, url + "workitems?ids=" + idsString + "&fields=System.Id,System.Title"))
{
detailsRequest.Headers.Add("Authorization", "Bearer " + token);
detailsRequest.Headers.Add("Accept", "application/json;api-version=" + apiVersion);
using (var detailsResponse = await client.SendAsync(detailsRequest))
{
var detailsContent = await detailsResponse.Content.ReadAsStringAsync();
var detailsWorkItems = JObject.Parse(detailsContent)["value"] as JArray;
foreach (dynamic workItem in detailsWorkItems)
{
Console.WriteLine("Work item: {0} ({1})",
workItem.fields["System.Id"],
workItem.fields["System.Title"]
);
}
}
}
}
}
}
any help with this would be appreciated,
thanks

You can add related sites to trusted sites (for example: https://app.vssps.visualstudio.com, https://login.live.com etc…).
Internet option=>Security
Select Trusted sites
Click sites
Type website address and click add
The simple way to know which URLs need to be added, you could send a simple Get Rest request (e.g. get work item REST API), it will pop up a window that contains site URL (will pop up many times for different URL), add these URL to trusted sites list.
Update:
Based on the response result, it isn’t related to enhanced security, the result means it isn’t authenticated. So the token is invalid, it is access token of OAuth, you need to get access token after register your app to VSTS.
More information, you can refer to this article.
There is a OAuth sample that you can refer. After you get access token, add it to request header and retrieve data from VSTS.
If you want to access VSTS through personal access token, the code like this: (check this article)
try
{
var username = "username";
var password = "password";
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(
new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", username, password))));
using (HttpResponseMessage response = client.GetAsync(
"https://{account}.visualstudio.com/DefaultCollection/_apis/build/builds").Result)
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
I am trying to access a local SharePoint site using a .net program and am having difficulties.
I don't want to use the SharePoint development environment (may have many developers work on this, and that is just one more thing to install).
I would also like to make this configurable so that I can change the site and list name without recompiling. I don't think I can do that with the Service References. If I can, how?
I also don't want the user to enter sharepoint validation information, I am ok with storing sharepoint login information in a .config file.
I believe I could do this with REST, but can't figure out how to create an AccessToken without using the Sharepoint development environment.
Any help would be appreciated.
The main problem I was having was not understanding that you could put other types of credentials in the request.Credentials property. Here is the code I created:
public bool CopyFileToSharePoint(string fileName, Stream fileStream)
{
var data = new byte[fileStream.Length];
fileStream.Read(data, 0, (int) fileStream.Length);
fileStream.Close();
var sharePointPath =
SharePointWebSiteUrl + "/_api/web/lists/getByTitle('" + SharePointListName + "')" +
"/RootFolder/Files/add(url='" + fileName + "',overwrite='true')";
var request = (HttpWebRequest) WebRequest.Create(sharePointPath);
request.Credentials = new NetworkCredential(SharePointUserName, SharePointPassword, SharePointLoginDomain);
request.Method = "POST";
request.Accept = "application/atom+xml";
request.Headers["X-RequestDigest"] = GetFormDigest(SharePointWebSiteUrl);
request.ContentType = "application/txt";
request.ContentLength = data.Length;
request.GetRequestStream().Write(data, 0, data.Length);
var response = (HttpWebResponse) request.GetResponse();
return response.StatusCode == HttpStatusCode.OK;
}
I'm sure it's not perfect, but it works.
I'm trying to simply upload a new blob to an Azure Storage countainer using WebClient like this :
var sas = "[a new generated sas with Read, Write, List & Delete permissions]";
var sData = "This is a test!";
var sEndPoint = "http://myaccount.blob.core.windows.net/mycontainer/MyTest.txt" + sas;
var clt = new WebClient();
var res = await clt.UploadStringTaskAsync(sEndPoint, "PUT", sData);
This is giving me a "(400) Bad Request." error. Am I doing anything wrong here?
Thanks
(By the way, I need to use REST instead of Client API since I'm in a Silverlight project)
You would need to define a request header (x-ms-blob-type) for blob type and set it's value to BlockBlob. Also for Put requests you would need to define the Content-Length request header as well. I wrote a blog post on Shared Access Signatures and performing some blob operations using that (with both REST API and Storage Client library) which you can read here: http://gauravmantri.com/2013/02/13/revisiting-windows-azure-shared-access-signature/.
and here's the code from that post on uploading blob. It uses HttpWebRequest/HttpWebResponse instead of WebClient:
static void UploadBlobWithRestAPISasPermissionOnBlobContainer(string blobContainerSasUri)
{
string blobName = "sample.txt";
string sampleContent = "This is sample text.";
int contentLength = Encoding.UTF8.GetByteCount(sampleContent);
string queryString = (new Uri(blobContainerSasUri)).Query;
string blobContainerUri = blobContainerSasUri.Substring(0, blobContainerSasUri.Length - queryString.Length);
string requestUri = string.Format(CultureInfo.InvariantCulture, "{0}/{1}{2}", blobContainerUri, blobName, queryString);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestUri);
request.Method = "PUT";
request.Headers.Add("x-ms-blob-type", "BlockBlob");
request.ContentLength = contentLength;
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(Encoding.UTF8.GetBytes(sampleContent), 0, contentLength);
}
using (HttpWebResponse resp = (HttpWebResponse)request.GetResponse())
{
}
}
When testing against the blob emulator this is the code I need to get it working:
var connection = ConfigurationManager.AppSettings["AzureStorageConnectionString"];
var storageAccount = CloudStorageAccount.Parse(connection);
var client = new WebClient();
client.Headers.Add("x-ms-blob-type", "BlockBlob");
client.Headers.Add("x-ms-version", "2012-02-12");
client.UploadData(string.Format(#"{0}/$root/{1}{2}", storageAccount.BlobEndpoint, myFileName, sharedAccessSignature), "PUT", _content);
I am using Azure Media Services and a Silverlight Player to play the streamed url
I am able to ingest, encode the video file as an asset file but when I go play the streamed url I am facing problem.
I use following code to fetch the url...
context = new CloudMediaContext(_accountName, _accountKey);
IAsset myAsset = GetAsset("UUID:7a32b941-30bd-4c96-bf4e-26df5022eec5");
var theManifest = from f in myAsset.AssetFiles
where f.Name.EndsWith(".ism")
select f;
var manifestFile = theManifest.First();
IAccessPolicy streamingPolicy = _context.AccessPolicies.Create("Streaming policy",
TimeSpan.FromDays(10),
AccessPermissions.Read);
ILocator originLocator = _context.Locators.CreateSasLocator(myAsset, streamingPolicy, DateTime.UtcNow.AddMinutes(-500));
GetAssetSasUrlList(myAsset, originLocator);
string urlForClientStreaming = originLocator.Path + manifestFile.Name + "/manifest";
Console.WriteLine("URL to manifest for client streaming: ");
Console.WriteLine(urlForClientStreaming);
this url comes like --
https://mediasvc06w4dq5k8vd08.blob.core.windows.net/asset-064ed2d5-e42d-4c49-98eb-a712db5c614f?st=2012-12-26T23%3A04%3A22Z&se=2013-01-05T23%3A04%3A22Z&sr=c&si=9350bd2f-ec23-40b2-b27a-248bba01b97e&sig=oGgesnr8mXjCdTM5Dz%2FQpFRBDR0g0%2F60ECoXY14EvsA%3DBigBuckBunny.ism/manifest
Its not working .
When I paste this url on browser directly ,I get following error
AuthenticationFailedServer failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:154422cf-822e-4bbc-af2a-fa69273dfb89 Time:2012-12-27T08:57:30.9509847ZSignature fields not well formed.
But if I go and publish asset from portal( www.manage.windowsazure.com )--
I get like following url on protal..
http://mediaervices.origin.mediaservices.windows.net/5edbeae7-c3e6-45c5-bc5c-70f46b526cb5/BigBuckBunny.ism/Manifest
And it works with my silverlight player..
Now problem is that I am not getting url which starts with http from code and the url starting with https is not working with my player.
I guessed that its security issue and tried to host my player in winows azure and tried to player there but no success.
No, not a security issue. You are requesting a SAS url for a Smooth asset, you need an Origin URL. The correct code snippet is here, on my blog:
http://blog-ndrouin.azurewebsites.net/?p=1931
Specifically:
private static string GetStreamingUrl(CloudMediaContext context, string outputAssetId)
{
var daysForWhichStreamingUrlIsActive = 365;
var outputAsset = context.Assets.Where(a => a.Id == outputAssetId).FirstOrDefault();
var accessPolicy = context.AccessPolicies.Create(outputAsset.Name, TimeSpan.FromDays(daysForWhichStreamingUrlIsActive), AccessPermissions.Read | AccessPermissions.List);
var assetFiles = outputAsset.AssetFiles.ToList();
var assetFile = assetFiles.Where(f => f.Name.ToLower().EndsWith("m3u8-aapl.ism")).FirstOrDefault();
if (assetFile != null)
{
var locator = context.Locators.CreateLocator(LocatorType.OnDemandOrigin, outputAsset, accessPolicy);
Uri hlsUri = new Uri(locator.Path + assetFile.Name + "/manifest(format=m3u8-aapl)");
return hlsUri.ToString();
}
assetFile = assetFiles.Where(f => f.Name.ToLower().EndsWith(".ism")).FirstOrDefault();
if (assetFile != null)
{
var locator = context.Locators.CreateLocator(LocatorType.OnDemandOrigin, outputAsset, accessPolicy);
Uri smoothUri = new Uri(locator.Path + assetFile.Name + "/manifest");
return smoothUri.ToString();
}
assetFile = assetFiles.Where(f => f.Name.ToLower().EndsWith(".mp4")).FirstOrDefault();
if (assetFile != null)
{
var locator = context.Locators.CreateLocator(LocatorType.Sas, outputAsset, accessPolicy);
var mp4Uri = new UriBuilder(locator.Path);
mp4Uri.Path += "/" + assetFile.Name;
return mp4Uri.ToString();
}
return string.Empty;
}
