RESTful API is currently a relatively mature set of Internet Application API design theory. With the mature and popular of restful APIs, the application development needs to invoke the RESTful API interface in the way of simulating HTTP request, and after a period of time IBM's cloud platform Blumemix the application of learning and language translation service, accumulated Java, ASP. Nodejs, Go, PHP, Python, Ruby and other languages call the rest API method, here together, and share with you.
For RESTful APIs Please refer to: Understanding RESTful architecture, RESTful API Design Guide
Java
Java in this area of the jar package should be more, such as httpclient, I use the most basic:
The authentication information object that contains the user name and password to access the translation service Authenticator auth = new Myauthenticator ("username", "password"); Authenticator.setdefault (auth); The connection between open and URL httpsurlconnection connection = (httpsurlconnection) realurl.openconnection (); Connection.setdoinput (true); Connection.setdooutput (TRUE);//Allow connection to submit information Connection.setrequestmethod ("GET"); Establish the actual connection Connection.connect ();

asp
Asp. Net uses the System.Net.Http.HttpClient class to implement API calls:
System.Net.Http.HttpClient HttpClient = new System.Net.Http.HttpClient ()//Convert service voucher to BASE64 encoded format byte[] auth = Encoding.UTF8.GetBytes ("User name: Password"); String auth64 = convert.tobase64string (auth);//Create and specify service credentials, authentication scheme is BasichttpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue ("Basic", auth64); retstring = await httpclient.getstringasync (URI);

Php
PHP uses the famous curl to implement API calls:
$ch = Curl_init (); curl_setopt ($ch, Curlopt_url, $url); curl_setopt ($ch, Curlopt_returntransfer, 1); The HTTPS request must have the following two items set curl_setopt ($ch, curlopt_ssl_verifyhost, 0); curl_setopt ($ch, Curlopt_ssl_verifypeer, FALSE); Set the voucher curl_setopt ($ch, curlopt_userpwd, ' Your user name: your password '); Execute request

Python
Using standard library urllib2 in Python to implement API calls
Passman = Urllib2. Httppasswordmgrwithdefaultrealm () #创建域验证对象 Passman.add_password (None, sURL, "Translation service username", "password") #设置域地址, username and password Auth_handler = Urllib2. Httpbasicauthhandler (Passman) #生成处理与远程主机的身份验证的处理程序 opener = Urllib2.build_opener (Auth_handler) # Returns a Openerdirector instance Urllib2.install_opener (opener) #安装一个openerDirector实例作为默认的开启者. response = Urllib2.urlopen (sURL) #打开URL链接, return response object rescontent = Response.read () #读取响应内容

Ruby
Ruby uses the Net::http class to implement API calls
http = net::http.new (uri.host, uri.port) Http.use_ssl = True Http.verify_mode = Openssl::ssl::verify_none request = net::http::get.new (Uri.request_uri) Request.basic_auth "username", "password"

Go
The go language uses the Net/http package to implement API calls, which has the advantage that we can write the username and password directly in the URL
url = "https://User name: password @gateway.watsonplatform.net/language-translation/api/v2/translate?"; RESP, err: = http. Get (URL) //Send HTTP GET request if err! = Nil { FMT. fprintf (W, err. Error ()) return } if resp! = Nil && resp. Body! = Nil { Defer resp. Body.close () } if resp. StatusCode! = http. Statusok { FMT. fprintf (w, errors. New (resp. Status). Error ()) return } data, err: = Ioutil. ReadAll (resp. Body) If err! = Nil { FMT. fprintf (W, err. Error ()) return }

Nodejs
Nodejs using HTTPS packets to implement API calls
Impersonation HTTP GET request Http.get ("https://translation service username: password @gateway.watsonplatform.net/language-translation/api/v2/translate?" + Data, function (gres) { var body = '; Gres.on (' Data ', function (d) { body + = D; }). On (' End ', function () { //console.log (gres.headers); Console.log (body); Output response content Res.send ("{\" text\ ": \" "+ Body +" \ "}");}) . On (' Error ', function (e) { console.log ("Got error:" + e.message); });
