一. 翻译接口：
目前有很多第三方翻译接口，比如有道词典，百度等，开发人员根据这些接口可自己实现中英翻译。
有道翻译的源码：需要自己申请key，然后填入
function translate($keyword){ $url = "http://fanyi.youdao.com/openapi.do?keyfrom=******&key=*******&type=data&doctype=json&version=1.1&q=".urlencode($keyword); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); if(curl_errno($ch)) { echo 'CURL ERROR Code: '.curl_errno($ch).', reason: '.curl_error($ch);} curl_close($ch); //var_dump($content); $youdao = json_decode($output, true); $errorcode = $youdao['errorCode']; $result = ""; if(isset($errorcode)){ switch ($errorcode){ case 0: $translation = $youdao['translation'][0]; //网络释义 $explains = $youdao['basic']['explains']; //基本解释 if ($translation != "") { $result = $translation; }else{ foreach ($explains as $value) { $result = $result."\n".$value; } } break; case 20: $result = "输入错误：要翻译的文本过长"; break; case 30: $result = "系统错误：无法进行有效的翻译"; break; case 40: $result = "输入错误：不支持的语言类型"; break; case 50: $result = "系统错误：无效的密钥，没有权限翻译"; break; default: $result = "系统错误：遇到未知错误，代码：".$errorcode; break; } } else{ $result = "没有获得翻译结果？请和我们联系"; } //return $youdao['translation']['0']; return trim($result);}二、调用实现
define("TOKEN", "qq62486"); $wechatObj = new wechatCallbackapiTest();$wechatObj->responseMsg(); class wechatCallbackapiTest{ public function valid() { $echoStr = $_GET["echostr"]; //valid signature , option if($this->checkSignature()){ echo $echoStr; exit; } } public function responseMsg() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; logger("R ".$postStr); //extract post data if (!empty($postStr)){ $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $RX_TYPE = trim($postObj->MsgType); switch ($RX_TYPE) { case "text": $resultStr = $this->receiveText($postObj); break; case "event": $resultStr = $this->receiveEvent($postObj); break; default: $resultStr = "unknow msg type: ".$RX_TYPE; break; } logger("T ".$resultStr); echo $resultStr; }else { echo ""; exit; } } private function checkSignature() { $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } private function receiveText($object) { $funcFlag = 0; $keyword = trim($object->Content); $resultStr = ""; $cityArray = array(); $contentStr = ""; $needArray = false; $illegal = false; $saytome = false; if (1 == 1){ $contentStr = translate($keyword); $resultStr = $this->transmitText($object, $contentStr, $funcFlag); return $resultStr; } //Content 消息内容，大小限制在2048字节，字段为空为不合法请求 return $resultStr; } private function receiveEvent($object) { $contentStr = ""; switch ($object->Event) { case "subscribe": $contentStr = "请直说，我将为你自动翻译"; break; case "unsubscribe": $contentStr = ""; break; case "CLICK": switch ($object->EventKey) { default: $contentStr = "receive a eventkey: ".$object->EventKey; break; } break; default: $contentStr = "receive a new event: ".$object->Event; break; } $resultStr = $this->transmitText($object, $contentStr); return $resultStr; } private function transmitText($object, $content, $flag = 0) { $textTpl = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[%s]]></Content><FuncFlag>%d</FuncFlag></xml>"; $resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $flag); return $resultStr; }}联系客服
