Microsoft翻译文本停止工作-PHP

Question

我一直在使用此库通过Microsoft认知翻译器翻译文本。

PHP Microsoft Translate package

我有一个Azure帐户，我认为我的端点和密钥仍然有效。尽管我拥有“免费”软件包，但在此期间，我没有进行任何更改。

我实际上已经翻译了多种语言的代码，并且之前运行良好。由于某种原因，它最近停止了工作。我编辑了帖子以设置：

$host = "https://api.cognitive.microsofttranslator.com", thank you (typo).

如果我将$ text设置为简单的东西，它实际上就可以工作：

$text = 'Guten Morgen!  Mit Corona zusammenraufen.Milde gesagt: Es sind keine besonders beruhigenden Nachrichten.';

返回英文：

{"text":"Good morning! To put it mildly, it's not particularly reassuring news.","to":"en"}

如果我将字符串稍微加长到：

$text = 'Guten Morgen!  Mit Corona zusammenraufen.  Milde gesagt: Es sind keine besonders beruhigenden Nachrichten. Milde gesagt: Es sind keine besonders beruhigenden Nachrichten.';

我得到一个：

failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request

以前使用更长的字符串进行输入。我对Azure有一个“免费”计划。我的Azure帐户现在是否可以限制字符串长度？

我拥有的代码是。还有一些额外的东西可用于将翻译内容放入数据库中。

$key = 'MicrosoftKEY';
$host = "https://api.cognitive.microsofttranslator.com";
$path = "/translate?api-version=3.0";
$languages = $data['languagearray'];  // array of languages to translate to.
$params = '&from=' . $data["from"] ;  // language to translate from
foreach ($languages as $language) {
$params .= "&to=" . $language;
}
$params .= "&textType=html";
$text = $data["text"];  // text to translate

if (!function_exists('com_create_guid')) {
  function com_create_guid() {
    return sprintf( '%04x%04x-%04x-%04x-%04x-%04x%04x%04x',
        mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ),

  }
}
// function to return the translated text, seem below, $json = jsonp_decode($result, true)[0]["translations"];

function Translate ($host, $path, $key, $params, $content) {

    $options = array (
        'http' => array (
            'header' => $headers,

            'content' => $content
        )
    );
    $context  = stream_context_create ($options);
    $result = file_get_contents ($host . $path . $params, false, $context);
    echo $result;
    return $result;
}
$requestBody = array (
    array (
        'Text' => $text,
    ),
);

function jsonp_decode($jsonp, $assoc = false) { // PHP 5.3 adds depth as third parameter to json_decode
    if($jsonp[0] !== '[' && $jsonp[0] !== '{') { // we have JSONP
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}

$content = json_encode($requestBody);
$result = Translate ($host, $path, $key, $params, $content);
// Note: We convert result, which is JSON, to and from an object so we can pretty-print it.
// We want to avoid escaping any Unicode characters that result contains. See:
// http://php.net/manual/en/function.json-encode.php
$json = jsonp_decode($result, true)[0]["translations"];
$conn = DatabaseFactory::getFactory()->getConnection();

foreach ($json as $language) {
    $query = 'UPDATE kronen_translations SET translated_text = ? WHERE language_code = ?';
    $parameters = [$language['text'], $language['to']];
    $stmt = $conn->prepare($query);
    $stmt->execute($parameters);
    echo $language['to'] . '<br>';
    echo $language['text'] . '<br>';
}

Answer 1

我进行了更多调查，最终向Microsoft Cognitive Services开了张罚单。这个脚本/几个月前运行良好，实际上我使用捆绑调用一次调用将几段翻译成大约40种不同的语言（几乎支持它们的全部功能），我得到的答复是所有的翻译。以前工作正常。

但是，翻译服务的API请求有字符限制：

参见：Request limits for Translator Text

“在您要翻译的所有目标语言中，每个翻译请求都限制为5,000个字符。例如，发送1,500个字符的翻译请求以翻译为3种不同的语言，则请求大小为1,500x3 = 4,500个字符，满足请求限制。按字符数收费，而不是按请求数收费。建议发送较短的请求。“

[使用40种不同的语言以及几段包含几百个字符的段落，我超出了限制。在使用MS支持对电子邮件进行交易之后，事实证明，由于去年年底和年底的一个错误，API要求限制没有得到强制实施，并且显然是最近对其进行了修复。

仅供参考，旧代码类似于以下内容，查询字符串大约有40个左右的＆to = lang＆。 。 。 。

$languages = $data['languagearray'];
$params = '&from=' . $data["from"] ;
foreach ($languages as $language) {
$params .= "&to=" . $language;
}
$params .= "&textType=html";
$text = $data["text"];

if (!function_exists('com_create_guid')) {
  function com_create_guid() {
    return sprintf( '%04x%04x-%04x-%04x-%04x-%04x%04x%04x',
        mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ),
        mt_rand( 0, 0xffff ),
        mt_rand( 0, 0x0fff ) | 0x4000,
        mt_rand( 0, 0x3fff ) | 0x8000,
        mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff )
    );
  }
}
function Translate ($host, $path, $key, $params, $content) {

    $headers = "Content-type: application/json\r\n" .
        "Content-length: " . strlen($content) . "\r\n" .
        "Ocp-Apim-Subscription-Key: $key\r\n" .
        "X-ClientTraceId: " . com_create_guid() . "\r\n";
    // NOTE: Use the key 'http' even if you are making an HTTPS request. See:
    // http://php.net/manual/en/function.stream-context-create.php
    $options = array (
        'http' => array (
            'header' => $headers,
            'method' => 'POST',
            'content' => $content
        )
    );
    $context  = stream_context_create ($options);
    $result = file_get_contents ($host . $path . $params, false, $context);
    echo $result;
    return $result;
}
$requestBody = array (
    array (
        'Text' => $text,
    ),
);

function jsonp_decode($jsonp, $assoc = false) { // PHP 5.3 adds depth as third parameter to json_decode
    if($jsonp[0] !== '[' && $jsonp[0] !== '{') { // we have JSONP
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}

$content = json_encode($requestBody);
$result = Translate ($host, $path, $key, $params, $content);
// Note: We convert result, which is JSON, to and from an object so we can pretty-print it.
// We want to avoid escaping any Unicode characters that result contains. See:
// http://php.net/manual/en/function.json-encode.php
$json = jsonp_decode($result, true)[0]["translations"];
$conn = DatabaseFactory::getFactory()->getConnection();

foreach ($json as $language) {
    $query = 'UPDATE kronen_translations SET translated_text = ? WHERE language_code = ?';
    $parameters = [$language['text'], $language['to']];
    $stmt = $conn->prepare($query);
    $stmt->execute($parameters);
    echo $language['to'] . '<br>';
    echo $language['text'] . '<br>';
}

允许您这样打出捆绑的电话，然后解码您返回的结果。

解决方案是进行一系列调用（在这种情况下，一次调用一次），每种语言一次，然后按顺序处理结果。新代码是这样的。也许有更好的方法，但是至少我可以处理大小合理的文本块。运行40种左右语言的脚本只需要一点时间，尽管仍然只有30秒，这取决于文本的大小。

function Translate ($host, $path, $key, $params, $content) {

    $headers = "Content-type: application/json\r\n" .
        "Content-length: " . strlen($content) . "\r\n" .
        "Ocp-Apim-Subscription-Key: $key\r\n" .
        "X-ClientTraceId: " . com_create_guid() . "\r\n";
    // NOTE: Use the key 'http' even if you are making an HTTPS request. See:
    // http://php.net/manual/en/function.stream-context-create.php
    $options = array (
        'http' => array (
            'header' => $headers,
            'method' => 'POST',
            'content' => $content
        )
    );
    $context  = stream_context_create ($options);
    $result = file_get_contents ($host . $path . $params, false, $context);
    echo $result;
    return $result;
}



function jsonp_decode($jsonp, $assoc = false) { // PHP 5.3 adds depth as third parameter to json_decode
    if($jsonp[0] !== '[' && $jsonp[0] !== '{') { // we have JSONP
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}

$key = 'xxxxx';
$host = "https://api.cognitive.microsofttranslator.com";
$path = "/translate?api-version=3.0";
$languages = $data['languagearray'];
// print_r($languages);
$conn = DatabaseFactory::getFactory()->getConnection();
$text = $data["text"];
foreach ($languages as $language) {
$params = '&from=' . $data["from"] ;
$params .= "&to=" . $language;
$params .= "&textType=html";
$text = $data["text"];

$requestBody = array (
    array (
        'Text' => $text,
    ),
);
$content = json_encode($requestBody);
$result = Translate ($host, $path, $key, $params, $content);
$json = jsonp_decode($result, true)[0]["translations"];

foreach ($json as $language) {
    $query = 'UPDATE kronen_translations SET translated_text = ? WHERE language_code = ?';
    $parameters = [$language['text'], $language['to']];
    $stmt = $conn->prepare($query);
    $stmt->execute($parameters);
    echo $language['to'] . '<br>';
    echo $language['text'] . '<br>';
