[英]Google Translate API and Character Encoding
I am using the below PHP code with Google's Translate API and I have read that json_encode
requires UTF-8 input, so was wondering how do I know if Google is returning UTF-8 encoded characters to me? 我使用下面的PHP代码与谷歌的Translate API,我已经读过
json_encode
需要UTF-8输入,所以我想知道如何知道谷歌是否向我返回UTF-8编码字符?
// URL Encode string
$str = urlencode($str);
// Make request
$response = file_get_contents('https://www.googleapis.com/language/translate/v2?key=' . GTRAN_KEY . '&target=es&source=en&q=' . $str);
// Decode json response to array
$json = json_decode($response,true);
if json_decode
fails (for any reason, including charset-problems) it will return null
, so you could check for that. 如果
json_decode
失败(由于任何原因,包括charset-problems),它将返回null
,因此您可以检查它。 to specifically chck the encoding, you could use mb_detect_encoding
. 要专门chck编码,你可以使用
mb_detect_encoding
。
if(!mb_detect_encoding($response, 'UTF-8', true)){
// error: no utf-8
}else{
$json = json_decode($response,true);
if($json === null){
// error: json_decode failed (or google returned 'null')
}else{
// ok, do great stuff here
}
}
