google中的400个错误请求使用curl翻译免费api

Question

我试图使用免费的谷歌翻译API，这是从火狐的S3谷歌翻译插件，即。

https://translate.google.com/translate_a/single?client=t&sl=auto&
tl=en&hl=en&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t
&dt=at&ie=UTF-8&oe=UTF-8&otf=2&srcrom=1&ssel=0&tsel=0&q=Hello

在PHP cURL ie中。

$isPOST=isset($_POST) && !empty($_POST);
$q=$isPOST ? $_POST['q'] : $_GET['q'];

$url='https://translate.google.com/translate_a/single';
$data='client=t&sl=auto&tl=en&hl=en&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&dt=at&ie=UTF-8&oe=UTF-8&otf=2&srcrom=1&ssel=0&tsel=0&q='.$q;
$ch=curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_URL, !$isPOST ? $url.'?'.$data : $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
if($isPOST){
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
$return=curl_exec($ch);
curl_close($ch);

我用ajax调用这个页面..。

$.ajax({
    type: text.length>750 ? 'post' : 'get',
    url: 'translate.php',
    data: 'q='+text,
    success: function(d){ alert(d); }
});

但这样做，我得到了谷歌翻译的回应，即。

Error: 400. That’s an error.
Your client has issued a malformed or illegal request. That’s all we know.

请帮我解决这个错误并得到翻译的文本。

对不起，我试着用同样的代码发邮件，结果成功了..谢谢大家。

Answer 2

我在浏览器中检查了您的URL，它显示了400个错误。这意味着非法请求。尝试http://www.sitepoint.com/using-google-translate-api-php/这个网址。

<?php
    $apiKey = '<paste your API key here>';
    $text = 'Hello world!';
    $url = 'https://www.googleapis.com/language/translate/v2?key=' . $apiKey . '&q=' . rawurlencode($text) . '&source=en&target=fr';

    $handle = curl_init($url);
    curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($handle);                 
    $responseDecoded = json_decode($response, true);
    curl_close($handle);

    echo 'Source: ' . $text . '<br>';
    echo 'Translation: ' . $responseDecoded['data']['translations'][0]['translatedText'];
?>

Answer 3

我在一个Visual 6项目中也有同样的问题，而Thamaraiselvam的评论引导我走向正确的方向。我正确地构建了URL，如果我在浏览器中尝试它，它就能工作，但是在vb6的http组件中它不能工作。解决方案是简单地url_encode发送的数据。(将其放入浏览器是自动完成的)

希望这能帮到别人。
