I want to use setEntity in my code with HttpURLConnection but Android Studio
doesn't recognize setEntity in my code
and I added this code to my Gradle:
org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2
but didn't work for me
here is an image of my code
enter image description here
This has been deprecated so you can't use it anymore or basically not required.follow link to docs
To post data, you can write data (queryString) after the connection is opened.The data parameters can be formed as string then, you need to send your data in form of byte, below code converts the data into byte to send
String urlParameters = "param1=a¶m2=b¶m3=c";
byte[] postData = urlParameters.getBytes( StandardCharsets.UTF_8 );
int postDataLength = postData.length;
String request = "http://example.com/index.php";
URL url = new URL(request);
HttpURLConnection conn= (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setInstanceFollowRedirects(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("charset", "utf-8");
conn.setRequestProperty("Content-Length", Integer.toString( postDataLength ));
conn.setUseCaches(false);
try( DataOutputStream wr = new DataOutputStream( conn.getOutputStream())) {
wr.write( postData );
}

I have successfully used the Azure DevOps API to create multiple wiki pages, via a standalone C# desktop app. Now I'm trying to attach an image (currently stored locally) to the wiki (as per https://learn.microsoft.com/en-us/rest/api/azure/devops/wiki/attachments/create?view=azure-devops-rest-6.0), but get an error
The wiki attachment creation failed with message : The input is not a
valid Base-64 string as it contains a non-base 64 character, more than
two padding characters, or an illegal character among the padding
characters.
This is the code that I use to read the image file and convert it to a Base64 string - is this correct?
string base64String = null;
string img = File.ReadAllText(att.Value);
byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(img);
base64String= Convert.ToBase64String(byteCredentials);
Then I create the "content" for the API call as
string data = #"{""content"": """ + base64String + #"""}";
and run the API call
string url = "https://dev.azure.com/{organization}/{project}/_apis/wiki/wikis/{wikiIdentifier}/attachments?name=Image.png&api-version=6.0";
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.ContentType = "application/octet-stream";
request.Method = "PUT";
request.Proxy.Credentials = CredentialCache.DefaultCredentials;
request.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(string.Format("{1}", "AzurePAT"))));
if (data != null)
{
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(data);
}
}
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
string result = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
result = reader.ReadToEnd();
}
Can anyone see anything wrong with any of this? The concept of setting up a "content" JSON with an encoded Base64 string doesn't seem to be documented, so have I done it correctly?
Any help or advice gladly appreciated, thanks
An image file does not contain text, it is a binary file, calling File.ReadAllText probably messes up the encoding. Try:
var img = File.ReadAllBytes(att.Value);
var base64String = Convert.ToBase64String(img);
In addition, the request expects the body to just be a string. You are passing JSON. Your code should look like this:
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(base64String);
}
I have the following code sample with which I'm trying to authenticate an Azure active directory user within a Xamarin forms app
The URL (I've removed the actual client ID) works fine in a browser but fails when trying to send the http request
The error message says 'the response type must include client_id'
string URL = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize?"
+ "client_id=xxxx-xxxxx-xxxxx-xxxxx-xxx"
+ "&response_type=code"
+ "&redirect_uri=https://login.microsoftonline.com/common/oauth2/nativeclient"
+ "&response_mode=query"
+ "&scope=openid%20offline_access%20https%3A%2F%2Fgraph.microsoft.com%2Fmail.read"
+ "&state=12345";
var webRequest = System.Net.WebRequest.Create(URL) as HttpWebRequest;
System.Console.WriteLine(URL);
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "text/html";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
HttpWebResponse resp = (HttpWebResponse)webRequest.GetResponse();
Stream resStream = resp.GetResponseStream();
StreamReader reader = new StreamReader(resStream);
ret = reader.ReadToEnd();
You put parameters in the URL, so you need to use GET method, instead of POST (like your browser does when you paste the URL in its address bar).
So, replace:
webRequest.Method = "POST";
by:
webRequest.Method = "GET";
and remove:
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
With the REST api, I am trying to get the documents out of a completed envelope. My header is using X-DocuSign-Authentication.
EnvelopesApi ap = new EnvelopesApi();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
EnvelopeDocumentsResult edr = ap.ListDocuments((AccountId, "xxx-xx-xxx");
List<EnvelopeDocument> docs = edr.EnvelopeDocuments;
foreach(EnvelopeDocument doc in docs)
{
Stream stream1 = ap.GetDocument(AccountId, "xxx-xx-xxx", doc.DocumentId);
StreamReader reader = new System.IO.StreamReader(stream1, encode);
var data = reader.ReadToEnd();
StreamWriter writer = new StreamWriter(#"C:\mysigneddoc.pdf");
writer.Write(data);
writer.Close();
}
When I try to open the completed pdf, I get the error stating that
the signers identity has not been verified.
Any ideas where I might be going wrong?
Please look at the API recipe here to download the documents from an envelope.
var ap = new EnvelopesApi();
var edr = ap.ListDocuments((AccountId, "xxx-xx-xxx");
List<EnvelopeDocument> docs = edr.EnvelopeDocuments;
foreach(EnvelopeDocument doc in docs)
{
// GetDocument() API call returns a MemoryStream
var docStream = (MemoryStream)envelopesApi.GetDocument(accountId, envelopeId, doc.DocumentId);
// let's save the document to local file system
filePath = #"C:\temp\" + Path.GetRandomFileName() + ".pdf";
fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();
}
You can also download the combined documents in an envelope using the GetEnvelopeDocuments api. You are not required to query for each individual document.
Combined PDF
Pass the string combined as the documentId.
Retrieve a PDF that contains the combined content of all documents and the certificate.
string envelopeId = "XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
string accountId = "XXXXXX";
var envApi = new EnvelopesApi();
// GetDocument() API call returns a MemoryStream
var docStream = (MemoryStream)envApi.GetDocument(accountId, envelopeId, "combined");
// let's save the document to local file system
string filePath = #"C:\temp\" + Path.GetRandomFileName() + ".pdf";
var fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();
ZIP file
Pass the string archive as documentId
Retrieve a ZIP archive that contains all of the PDF documents, the certificate, and any .WAV files used for voice authentication.
var envApi = new EnvelopesApi();
// GetDocument() API call returns a MemoryStream
var docStream = (FileStream)envApi.GetDocument(accountId, envelopeId, "archive");
// let's save the document to local file system
string filePath = #"C:\temp\" + Path.GetRandomFileName() + ".zip";
var fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();
I've followed instructions on how creating a ServiceStack here at:
https://github.com/ServiceStack/ServiceStack/wiki/Create-your-first-webservice
I'm sure I have followed it to the letter, but as soon as I run the web application. I get a 'Snapshot' view of my response. I understand this happens when I don't have a default view/webpage. I set up the project as a ASP.net website, not a ASP.net MVC website. Could that be the problem?
I also wrote a test console application with the following C# code. It got the response as a HTML webpage rather than as a plain string e.g. "Hello, John".
static void sendHello()
{
string contents = "john";
string url = "http://localhost:51450/hello/";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.ContentLength = contents.Length;
request.ContentType = "application/x-www-form-urlencoded";
// SEND TO WEBSERVICE
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(contents);
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string result = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
result = reader.ReadToEnd();
}
Console.WriteLine(result);
}
How can I switch off the 'snapshot' view? What am I doing wrong?
The browser is requesting html so ServiceStack is returning the html snapshot.
There are a couple of ways to stop the snapshot view:
First is to use the ServiceClient classes provided by servicestack. These also have the advantage of doing automatic routing and strongly typing the response DTOs.
Next way would be to set the Accept header of the request to something like application/json or application/xml which would serialize the response into json or xml respectively. This is what the ServiceClients do internally
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Accept = "application/json";
...
Another method would be to add a query string parameter called format and set it to json or xml
string url = "http://localhost:51450/hello/?format=json";
Putting the specific format requesting is the practical way to do this
string url = "http://localhost:51450/hello/?format=json";
I suggest simply deleting this feature.
public override void Configure(Container container)
{
//...
this.Plugins.RemoveAll(p => p is ServiceStack.Formats.HtmlFormat);
//...
}
Now all requests with the Content-Type=text/html will be ignored.

session.setConvertMIME(false);

var bytes = outputStream.toByteArray();

var passChunk:com.itextpdf.text.Chunk = new com.itextpdf.text.Chunk("Hello");
document.add(new com.itextpdf.text.Paragraph(passChunk));
document.close();
}
you probably would be better off writing a small Java wrapper class.
For starters you need:
var stream:NotesStream = session.createStream();
stream.setContents(inputStream);
stream.setPosition(0);
so the stream is at the beginning.
Update:
Also you have:
var bytes = outputStream.toByteArray();
var inputStream:java.io.ByteArrayInputStream = new java.io.ByteArrayInputStream(bytes);
stream.setContents(inputStream);
where I would write:
var bytes = outputStream.toByteArray();
stream.write(bytes);
Still, make a helper in Java.
