Getting access tokens for integrating Microsoft Translator Services in application

I've drawn a picture here to show the business logic

Before we call Microsoft Translator Server, we need to get a token, and this token is valid for 10 minutes. The following table lists the required parameters and the description for the

Parameters	Describe
client_id	Required, refers to the client ID of the application you registered in Azuzre
Client_secret	Required, refers to the client key that you registered the application in Azuzre
Scope	required, default use of http://api.microsofttranslator.com
Grant_type	Required, use "Client_credentials" by default

What Azure returns to us is also four properties, and returns as JSON, with the following table listing properties and corresponding descriptions

Property	Describe
Access_token	Verify that you can access the Microsoft translation API access token
Token_type	The format of the access token.
Expires_in	The number of seconds the access token is invalid
Scope	This token is a valid domain. For the Microsoft Translator API, the domain name is http://api.microsofttranslator.com.

The Bing AppID mechanism is deprecated and is no longer supported. As mentioned above, you must obtain an access token to use the Microsoft translation API. Access tokens are more secure, and access tokens can be called by subsequent programs within a specified time

Note the following two points

1. Use the value "Bearer" +Access_toke as the access token

2. The token is valid for 10 minutes and must be re-applied if it expires

Use the class Admaccesstoken below to store the properties returned by Azure

1 [DataContract]2     classAdmaccesstoken3     {4 [DataMember]5          Public stringAccess_token {Get;Set; }6 7 [DataMember]8          Public stringToken_type {Get;Set; }9 Ten [DataMember] One          Public stringexpires_in {Get;Set; } A  - [DataMember] -          Public stringScope {Get;Set; } the  -}

The four properties of this class correspond to the properties returned by Azure, and add [Datacontract][datamember] aspects to the returned JSON serialized object as Admaccesstoken

Next use a class admauthentication, which is used to help us complete the request for the token

 public class Admauthentication {public static readonly string Datamarketaccessuri = "Https://datamarket.access        Control.windows.net/v2/oauth2-13 ";        private string ClientId {get; set;}        private string Clientsecret {get; set;}        Private string Scope {get; set;}        private string Grant_type {get; set;}        Private string Request {get; set;}        Public Admaccesstoken token {get; set;}            Public Admauthentication (String clientId, String clientsecret) {This.clientid = ClientId;            This.clientsecret = Clientsecret; This.request = string. Format ("grant_type=client_credentials&client_id={0}&client_secret={1}&scope=http://            Api.microsofttranslator.com ", Httputility.urlencode (ClientId), Httputility.urlencode (Clientsecret));        This.token = HttpPost (Datamarketaccessuri, this.request); } Private Admaccesstoken HttpPost (string Datamarketaccessuri, String requestdetails) {           Prepare OAuth request WebRequest WebRequest = WebRequest.Create (Datamarketaccessuri);            Webrequest.contenttype = "application/x-www-form-urlencoded";            Webrequest.method = "POST";            byte[] bytes = Encoding.ASCII.GetBytes (requestdetails); webrequest.contentlength = bytes.            Length; using (Stream OutputStream = Webrequest.getrequeststream ()) {outputstream.write (bytes, 0, bytes .            Length); } using (WebResponse WebResponse = Webrequest.getresponse ()) {datacontractjsonserial                Izer serializer = new DataContractJsonSerializer (typeof (Admaccesstoken)); Get deserialized object from JSON stream Admaccesstoken token = (admaccesstoken) serializer.                ReadObject (WebResponse.GetResponseStream ());            return token; }        }}

OK, now that the token request has been completed, you can then use the token to get the translation service.
