微信公众平台开发--谷歌翻译

我是靠谱客的博主高挑香烟，这篇文章主要介绍微信公众平台开发--谷歌翻译，现在分享给大家，希望可以做个参考。

1）Google翻译接口

2）微信调用

3）效果展示

----------------------------------------------------------------------------------------

1）Google翻译接口

Google提供翻译的API接口,参见https://developers.google.com/translate/v2/getting_started

but

Google Translate API is a paid service.

so

想利用Google Translate API free charge 就要另外想办法了

Google提供免费的在线翻译功能,因此,可以通过Web发送翻译请求给Google,接收它的html返回,然后,通过分析html获取翻译后的文字.

复制代码function translate_web($text, $language="auto|en") { 
	if (empty($text)) return false; 
	
	$url = "http://google.cn/translate_t?ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);	
    	$html=file_get_contents($url);
	
	// parse html 
	// html souce: TTS_TEXT_SIZE_LIMIT=100;TRANSLATED_TEXT='世界，你好！';INPUT_TOOL_PATH='//www.google.com';
	$mode= ("/TRANSLATED_TEXT='(.*)';INPUT_TOOL_PATH/");
	if (preg_match($mode,$html,$out)){
		return $out[1];//ret;
	}
}1

	if (empty($text)) return false; 
	
	$url = "http://google.cn/translate_t?ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);	
    	$html=file_get_contents($url);
	
	// parse html 
	// html souce: TTS_TEXT_SIZE_LIMIT=100;TRANSLATED_TEXT='世界，你好！';INPUT_TOOL_PATH='//www.google.com';
	$mode= ("/TRANSLATED_TEXT='(.*)';INPUT_TOOL_PATH/");
	if (preg_match($mode,$html,$out)){
		return $out[1];//ret;
	}
}

更有甚者,有人发现通过http://translate.google.com/translate_a/t?client=p与Google交互可以得到json返回,这就相当于API使用了

复制代码function translate_json($text, $language="auto|en") { 
	if (empty($text)) return false; 
	
	$url = "http://translate.google.cn/translate_a/t?client=p&ie=UTF-8&oe=UTF-8&langpair=".$language."&text=".urlencode($text);
	$json=file_get_contents($url);
	$data = json_decode($json);
	return $data->sentences[0]->trans;	
}1

	$json=file_get_contents($url);
	$data = json_decode($json);
	return $data->sentences[0]->trans;

Google翻译接口示例: http://download.csdn.net/detail/d_eng/6563915

这里要注意的有两个问题

1)编码问题,例子中都采用utf-8,连php文件的属性都是utf-8

2)google问题,google在中国不保证一直能连上,虽然有多个链接 google.com/google.cn/google.com.hk

2）微信调用

有了接口,在微信中调用就简单了

接口文件 translate_func.php (save as utf-8)
