用JavaScript和Node.js翻译API

我想要：借助Bing翻译服务翻译文本

问题：我收到消息：

networking令牌最后必须有签名。 传入的令牌在令牌末尾没有签名。

编码之前我的令牌：

http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier=Subtitles&http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider=https://datamarket.accesscontrol.windows.net/&Audience=http://api.microsofttranslator.com&ExpiresOn=1411488480&Issuer=https://datamarket.accesscontrol.windows.net/&HMACSHA256=DsdsshfhhegefrgradfsdffqI= 

码：

 var request = require('request'); var querystring = require('querystring'); /** * Demo for translating a 'Hello world' from en to uk with help of Bing Translator service */ (function() { var makeTranslateRequest = function(token) { //I provided you my token at this point var opts = { text: 'Hello world', from: 'en-gb', to: 'ru' }; request.get({ url: "http://api.microsofttranslator.com/v2/Http.svc/Translate?contentType=text/plain&from=" + opts.from + "&to=" + opts.to + "&text=" + opts.text, headers: { 'Authorization': encodeURIComponent('Bearer' + token).replace(/'/g,"%27").replace(/"/g,"%22") } },function(err,res,body) { var translated = body; console.log('translated: ' + translated); }); } /** * Get token and make translate request in a callback */ var requestOpts = querystring.stringify({ client_id: 'Subtitles', client_secret: 'X...................................s=', scope: 'http://api.microsofttranslator.com', grant_type: 'client_credentials' }); request.post({ encoding: 'utf8', url: "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13", body: requestOpts }, function(err, res, body){ var decoded = decodeURIComponent(body.replace(/\+/g, " ")) var token = JSON.parse(decoded).access_token; makeTranslateRequest(token); }); })();

我在这里读了一些关于令牌的XML解码的东西。 所以我决定用XMLHTTPRequestreplace节点请求模块。

工作示例：

 var request = require('request'); var querystring = require('querystring'); var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest; /** * Demo for translating a 'Hello world' from en to uk with help of Bing Translator service */ (function() { //INSTEAD OF request.get({}) I use XMLHTTPRequest! Also I stoped to decoding/encoding token. That's the solution. var makeTranslateRequest = function(token) { var xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", "http://api.microsofttranslator.com/v2/Http.svc/Translate?from=en&to=ru&text=Good", true); xmlhttp.setRequestHeader('Authorization', 'Bearer ' + token); xmlhttp.onreadystatechange = function(){ if (xmlhttp.readyState==4 && xmlhttp.status==200){ console.log(xmlhttp.responseText); } } xmlhttp.send(); } /** * Get token and make translate request in a callback */ var requestOpts = querystring.stringify({ client_id: 'Subtitles', client_secret: 'X............................s=', scope: 'http://api.microsofttranslator.com', grant_type: 'client_credentials' }); request.post({ encoding: 'utf8', url: "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13", body: requestOpts }, function(err, res, body) { var token = JSON.parse(body).access_token; makeTranslateRequest(token); }); })();
