Google speech to text API in C# stopped working

I am trying to convert voice to text using Google Speech API. I have a sample code below. It was working fine, it stopped working suddenly and now it always throws the error - 400 bad request. I am using GOOGLE_SPEECH_KEY for authentication without OAuth2 token.
Not sure what exactly I'm missing. Do I need to create OAuth authentication or do I need to modify any console settings in google portal or need to modify the code itself ? Please help!
I used all the below api's and same 400 error:
1. url = "https://speech.googleapis.com/v1beta1/speech:syncrecognize?key=" + ACCESS_GOOGLE_SPEECH_KEY;
2. url = "https://speech.googleapis.com/v1/speech:recognize?key=" + ACCESS_GOOGLE_SPEECH_KEY;
3. url = "https://speech.googleapis.com/v1p1beta1/speech:recognize?key=" + ACCESS_GOOGLE_SPEECH_KEY;
public static string GoogleSpeechToTextApi(string flacUrl)
{
string pTranscriptText = "None", pTranscriptConfidence = "";
string appendText = "";
try
{
// Stream responseStream = imageResponse.GetResponseStream();
if (flacUrl != null)
{
string blobURI = flacUrl;
WebClient myWebClient = new WebClient();
Stream fileStream = myWebClient.OpenRead(blobURI);
byte[] BA_AudioFile = null;
using (var stream2 = new MemoryStream())
{
fileStream.CopyTo(stream2);
stream2.SetLength(stream2.Length);
stream2.Read(stream2.GetBuffer(), 0, (int)stream2.Length);
BA_AudioFile = stream2.GetBuffer();
}
string audioInput = Convert.ToBase64String(BA_AudioFile);
Config config = new Config();
config.encoding = "flac";
config.languageCode = "en";
config.sampleRate = "8000";
Audio audio = new Audio();
audio.content = audioInput;
JsonRequest request = new JsonRequest();
request.config = config;
request.audio = audio;
string json = JsonConvert.SerializeObject(request);
string url = "https://speech.googleapis.com/v1beta1/speech:syncrecognize?key=" + ACCESS_GOOGLE_SPEECH_KEY; // original api url
//url = "https://speech.googleapis.com/v1/speech:recognize?key=" + ACCESS_GOOGLE_SPEECH_KEY; // tested with this
//url = "https://speech.googleapis.com/v1p1beta1/speech:recognize?key=" + ACCESS_GOOGLE_SPEECH_KEY; // tested with this
WebRequest webRequest = WebRequest.Create(url);
webRequest.Method = "POST";
byte[] byteArray = Encoding.UTF8.GetBytes(json);
webRequest.ContentLength = byteArray.Length;
Stream dataStream = webRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse response = webRequest.GetResponse();
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
RootObject ro = JsonConvert.DeserializeObject<RootObject>(responseFromServer);
dynamic JsonArray = JsonConvert.DeserializeObject(responseFromServer);
var jsonResult = JsonArray["results"];
foreach (var item in jsonResult)
{
appendText += item.alternatives[0].transcript;
}
}
return appendText;
}
catch (Exception ex)
{
return appendText = "Error";
}
}
}
}

Error 400 means that your request is not correct. You can try encoding = linear16, audioChannelCount = 2 and sampleRateHertz = 16000 with file wav.
Btw, you can pass your key in header request instead in your url

Get GitHub Rest API User info C# code

https://api.github.com/users/[UserName] can be accessed via browser. I get a Json result. But I want to retrieve the same information programmatically.
I'm using the below code, which is not working as expected. Please advice.
var credentials =
string.Format(System.Globalization.CultureInfo.InvariantCulture, "{0}:",
githubToken);
credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(credentials));
client.DefaultRequestHeaders.Authorization = new
AuthenticationHeaderValue("Basic", credentials);
var contents =
client.GetStreamAsync("https://api.github.com/users/[userName]").Result;
As a result of the above code, I'm getting "Aggregate Exception".
How to achieve the requirement using c# code??? Please help
Note: Not expecting a solution with Octokit. Need proper c# code.

I found the solution. Here is the code.
HttpWebRequest webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "GET";
webRequest.UserAgent = "Anything";
webRequest.ServicePoint.Expect100Continue = false;
try
{
using (StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream()))
{
string reader = responseReader.ReadToEnd();
var jsonobj = JsonConvert.DeserializeObject(reader)
}
}
catch
{
return;
}
}

Below c# code is not reading websites or webpage from given urls

WebRequest request = WebRequest.Create(url);
WebRequest.DefaultWebProxy = null;
request.Proxy = null;
WebResponse response = request.GetResponse();
Stream data = response.GetResponseStream();
using (StreamReader sr = new StreamReader(data))
{
html = sr.ReadToEnd();
}
The above code not able to read/download the following webpages:
1) https://en.wikipedia.org/wiki/Unified_Payments_Interface
2) http://www.npci.org.in/UPI_Background.aspx

This may help you below code contains for both to get and post data:
public static string PostContent(this Uri url, string body, string contentType = null)
{
var request = WebRequest.Create(url);
request.Method = "POST";
if (!string.IsNullOrEmpty(contentType)) request.ContentType = contentType;
using (var requestStream = request.GetRequestStream())
{
if (!string.IsNullOrEmpty(body)) using (var writer = new StreamWriter(requestStream)) { writer.Write(body); }
using (var response = request.GetResponse() as HttpWebResponse)
{
using (var stream = response.GetResponseStream())
using (var reader = new StreamReader(stream))
{
return reader.ReadToEnd();
}
}
}
}
public static string GetContent(this Uri url)
{
WebClient client = new WebClient();
try
{
using (client)
{
client.Encoding = Encoding.UTF8;
return client.DownloadString(url);
}
}
catch (WebException)
{
return "";
}
finally
{
client.Dispose();
client = null;
}
}

please note that .aspx file extension design the server-side page and in consequence you will be able to download only the html page that display when you navigate on these sites (this is the same for .php files).
but if you want to download the frontend view this should work :
using System.Net;
...
WebClient client = new WebClient();
client.DownloadFile("Your url","download location");

Box API Create Shared link

I am trying to upload some documents to Box and create and retrieve a shared link for each of them.
This is the code I am using for it, but I always retrieve 403:access_denied_insufficient_permissions.
Any idea of why this is happening?
Hope you can help me! Thanks.
// CREATE THE FILE
BoxFileRequest req = new BoxFileRequest
{
Name = zipFile.Name,
Parent = new BoxRequestEntity { Id = newFolder.Id}
};
BoxFile uploadedFile = client.FilesManager.UploadAsync(req, stream).Result;
//REQUEST SHARED LINK
BoxSharedLinkRequest sharedLinkReq = new BoxSharedLinkRequest()
{
Access = BoxSharedLinkAccessType.open,
Permissions = new BoxPermissionsRequest
{
Download = BoxPermissionType.Open,
Preview = BoxPermissionType.Open,
}
};
BoxFile fileLink = fileManager.CreateSharedLinkAsync(uploadedFile.Id, sharedLinkReq).Result;

you need to give the access token and url. I have use the Following code and in JSON Format you will get the Response. For more reference check the box API document
HttpWebRequest httpWReq = HttpWebRequest)WebRequest.Create("https://api.box.com/2.0/folders/" + FolderID);
ASCIIEncoding encoding = new ASCIIEncoding();
string putData = "{\"shared_link\": {\"access\": \"open\"}}";
byte[] data = encoding.GetBytes(putData);
httpWReq.Method = "PUT";
httpWReq.Headers.Add("Authorization", "Bearer ");
httpWReq.ContentType = "application/json";
httpWReq.ContentLength = data.Length;
Use the httpwebrequest PUT method after this.
Mark it as Answer if its helpful.

It looks as if you are using the 3rd party BoxSync V2 API object. If you would like to just code to the API directly I had a similar issue that you are having. If you view this post you will see the answer. Here is the code I use and it works.
string uri = String.Format(UriFiles, fileId);
string response = string.Empty;
string body = "{\"shared_link\": {\"access\": \"open\"}}";
byte[] postArray = Encoding.ASCII.GetBytes(body);
try
{
using (var client = new WebClient())
{
client.Headers.Add("Authorization: Bearer " + token);
client.Headers.Add("Content-Type", "application/json");
response = client.UploadString(uri, "PUT", body);
}
}
catch (Exception ex)
{
return null;
}
return response;

How do I programatically download a file from a sharepoint site?

I have a sharepoint site that has an excel spreadsheet that I need to download on a schedulad basis
Is this possible?

Yes it is possible to download the file from sharepoint.
Once you have the url for the document, it can be downloaded using HttpWebRequest and HttpWebResponse.
attaching a sample code
DownLoadDocument(string strURL, string strFileName)
{
HttpWebRequest request;
HttpWebResponse response = null;
request = (HttpWebRequest)WebRequest.Create(strURL);
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.Timeout = 10000;
request.AllowWriteStreamBuffering = false;
response = (HttpWebResponse)request.GetResponse();
Stream s = response.GetResponseStream();
// Write to disk
if (!Directory.Exists(myDownLoads))
{
Directory.CreateDirectory(myDownLoads);
}
string aFilePath = myDownLoads + "\\" + strFileName;
FileStream fs = new FileStream(aFilePath, FileMode.Create);
byte[] read = new byte[256];
int count = s.Read(read, 0, read.Length);
while (count > 0)
{
fs.Write(read, 0, count);
count = s.Read(read, 0, read.Length);
}
// Close everything
fs.Close();
s.Close();
response.Close();
}
You can also use the GetItem API of Copy service to download a file.
string aFileUrl = mySiteUrl + strFileName;
Copy aCopyService = new Copy();
aCopyService.UseDefaultCredentials = true;
byte[] aFileContents = null;
FieldInformation[] aFieldInfo;
aCopyService.GetItem(aFileUrl, out aFieldInfo, out aFileContents);
The file can be retrieved as a byte array.

You can also do this:
try
{
using (WebClient client = new WebClient())
{
client.Credentials = new NetworkCredential("username", "password", "DOMAIN");
client.DownloadFile(http_path, path);
}
}
catch (Exception ex)
{
MessageBox.Show("Error: " + ex.Message);
}

The link the to document in Sharepoint should be a static URL. Use that URL in whatever solution you have to grab the file on your schedule.

Why not just use wget.exe <url>. You can put that line in a batch file and run that through windows scheduler.
