谷歌通过 PHP Curl 翻译

Question

我正在尝试使用 Google URL 获取从俄语或中文或许多其他语言到英语的翻译，它在 CURL 代码中不起作用，当我在邮递员应用程序中使用相同的 URL 时，它起作用。 我尝试了很多东西，也将代码从邮递员导入到 PHP 文件，但仍然是同样的问题。 也（utf-8 解码）工作一点，但不完全。为 2 种不同语言添加 2 条评论尝试它们，您可以看到错误

<?php
    header('Content-Type: application/json; charset=utf-8');

    $dtext = "説明が丁寧、かつ、事例があり、理解しやすいから。";
    // the next comment text work in $dtext 
    // Boa explicação do instrutor sobre os conteúdos do curso, mas as legendas não estão muito boas, tradução está um pouco mal feita.

    // Бодро рассказывает и в то же время все понятно, в общем привлекает тем что это не нудно. //this also not works

    $text = str_replace(" ","%20",$dtext);
    $host = "https://translate.google.com/translate_a/single?client=webapp&sl=auto&tl=en&hl=en&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&dt=gt&pc=1&otf=1&ssel=0&tsel=0&kc=1&tk=&q={$text}";

    $curl = curl_init();

Answer 1

问题是，根据您的代码产生的错误，归结为缺少 SSL 身份验证。 我在您的代码中观察到的错误是：

cURL 错误 #：SSL 证书问题：无法获取本地颁发者证书

在写下初始答案后看到您的评论，答案要简单得多 - 您需要对要翻译的短语进行urlencode 。

/* Use an non-SSL endpoint to eliminate Certificate errors - Not the greatest solution IMO! */
$host = "http://translate.google.com/translate_a/single?client=webapp&sl=auto&tl=en&hl=en&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&dt=gt&pc=1&otf=1&ssel=0&tsel=0&kc=1&tk=&q=".urlencode( $dtext );

$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_URL => $host,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_HTTPHEADER => array(
        "Accept: */*",
        "Accept-Encoding: gzip, deflate",
        "Cache-Control: no-cache",
        "Connection: keep-alive",

$response = utf8_decode( curl_exec( $curl ) );

if ( $err ) {
