使用JavaScript实现谷歌批量翻译接口的代码
谷歌翻译API是一个付费服务，需要注册并获取API密钥。以下是一个简单的JavaScript代码示例，使用`fetch`函数调用谷歌翻译API进行批量翻译： ```javascript const apiKey = '你的谷歌翻译API密钥'; const texts = ['你好', '世界']; const targetLanguage = 'zh-CN'; function translateText(text, targetLanguage) { const url = `https://translation.googleapis.com/language/translate/v2?key=${apiKey}&q=${encodeURIComponent(text)}&target=${targetLanguage}`; return fetch(url) .then(response => response.json()) .then(data => data.data.translations[0].translatedText); } async function batchTranslate(texts, targetLanguage) { const translations = await Promise.all(texts
asyncfunctiontranslation(array){varsplicing=[]if(!(arrayinstanceofArray)){array=[array]}for(leti=0;i<array.length;i++){splicing.push({"originalText":array[i],"translatedText":null,"detectedLanguage":null,"status":"translating","waitTranlate":{}})}returnawaitmakeRequest("auto","zh-CN",splicing)//无并发限制接口asyncfunctionmakeRequest(sourceLanguage,targetLanguage,requests){returnawaitnewPromise((resolve,reject)=>{constxhr=newXMLHttpRequest();xhr.open("POST","https://translate.googleapis.com/translate_a/t?anno=3&client=te&v=1.0&format=html"+GetExtraParameters(sourceLanguage,targetLanguage,requests));xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");xhr.responseType="json";xhr.onload=(event)=>{resolve(xhr.response);};xhr.onerror=xhr.onabort=xhr.ontimeout=(event)=>{console.error(event);reject();};xhr.send(getRequestBody(sourceLanguage,targetLanguage,requests));});functiongetRequestBody(sourceLanguage,targetLanguage,requests){returnrequests.map((info)=>`&q=${encodeURIComponent(info.originalText)}`).join("");}functionGetExtraParameters(sourceLanguage,targetLanguage,requests){return`&sl=${sourceLanguage}&tl=${targetLanguage}&tk=${calcHash(requests.map((info)=>info.originalText).join(""))}`functioncalcHash(query){constwindowTkk="448487.932609646";consttkkSplited=windowTkk.split(".");consttkkIndex=Number(tkkSplited[0])||0;consttkkKey=Number(tkkSplited[1])||0;constbytesArray=transformQuery(query);letencondingRound=tkkIndex;for(constitemofbytesArray){encondingRound+=item;encondingRound=shiftLeftOrRightThenSumOrXor(encondingRound,"+-a^+6");}encondingRound=shiftLeftOrRightThenSumOrXor(encondingRound,"+-3^+b+-f");encondingRound^=tkkKey;if(encondingRound<=0){encondingRound=(encondingRound&2147483647)+2147483648;}constnormalizedResult=encondingRound%1000000;returnnormalizedResult.toString()+"."+(normalizedResult^tkkIndex);functiontransformQuery(query){/**@type{Array<number>}*/constbytesArray=[];letidx=0;for(leti=0;i<query.length;i++){letcharCode=query.charCodeAt(i);if(128>charCode){bytesArray[idx++]=charCode;}else{if(2048>charCode){bytesArray[idx++]=(charCode>>6)|192;}else{if(55296==(charCode&64512)&&i+1<query.length&&56320==(query.charCodeAt(i+1)&64512)){charCode=65536+((charCode&1023)<<10)+(query.charCodeAt(++i)&1023);bytesArray[idx++]=(charCode>>18)|240;bytesArray[idx++]=((charCode>>12)&63)|128;}else{bytesArray[idx++]=(charCode>>12)|224;}bytesArray[idx++]=((charCode>>6)&63)|128;}bytesArray[idx++]=(charCode&63)|128;}}returnbytesArray;}functionshiftLeftOrRightThenSumOrXor(num,optString){for(leti=0;i<optString.length-2;i+=3){/**@type{string|number}*/letacc=optString.charAt(i+2);if("a"<=acc){acc=acc.charCodeAt(0)-87;}else{acc=Number(acc);}if(optString.charAt(i+1)=="+"){acc=num>>>acc;}else{acc=num<<acc;}if(optString.charAt(i)=="+"){num+=acc&4294967295;}else{num^=acc;}}returnnum;}}}}}console.log(awaittranslation(['hi','omg','yes']));
