我需要向Google Translate Text-To-Speech API提出请求。我有一个启用的密钥但仍然被No Access-Control-Allow-Origin阻止。
我在这里发布了更多相关内容:
Google Translate API - No Access Control Origin with Text to Speech
以下来源http://weston.ruter.net/2009/12/12/google-tts/和Request to Google Text-To-Speech API表示
如果HTTP请求包含Referer,Google会返回404错误 标题而不是空字符串。
请求如下:
$.get('https://translate.google.com/translate_tts?key='+myKey+'&ie=utf-8&tl=en&q=Hello+world',
function (returned_data) {
如何隐藏或删除引荐来源标题,以免我被阻止?
this source说要把https://href.li/...
放在前面。所以我把它改成了:
$.get('https://href.li/?https://translate.google.com/translate_tts?key='+key+'&ie=utf-8&tl=zh-CN&q=你好',
我仍被封锁。
服务器端尝试:无响应。
This blog提供了一个服务器端脚本,用于将引用者设置为空字符串。他说:
这会从该接入点获取信息并立即将其吐出。但在使用file_get_contents请求数据之前,Referer标头设置为空字符串。
/php/testPHP.php:
$qs = http_build_query(array("ie" => "utf-8","tl" => $_GET["tl"], "q" => $_GET["q"]));
$ctx = stream_context_create(array("http"=>array("method"=>"GET","header"=>"Referer: \r\n")));
$soundfile = file_get_contents("http://translate.google.com/translate_tts?".$qs, false, $ctx);
header("Content-type: audio/mpeg");
header("Content-Transfer-Encoding: binary");
header('Pragma: no-cache');
header('Expires: 0');
echo($soundfile);
index.php(root):
<audio controls="controls" autoplay="autoplay" style="display:none;">
<source src="/php/testPHP.php?translate_tts?tl=en&q=the%20brown%20fox%20jumped%20over%20the%20lazy%20dog." type="audio/mpeg" />
</audio>
tail -f apache错误日志:

JSONP尝试:所以我想也许将回复对象包装在<script>
中可以解决问题。我没有回复。
$.ajax({
url: 'https://translate.google.com/translate_tts?key='+key+'&ie=utf-8&tl=zh-CN&q=你好',
type: 'GET',
dataType: 'jsonp',
error: function(xhr, status, error) {
alert("error");
},
success: function(json) {
alert("success");
}
});
HTML / JS文字转语音尝试: 404阻止
js:
<script>
$(function() {
$('a.say').on('click', function(e) {
e.preventDefault();
var text = $('input[name="text"]').val();
text = encodeURIComponent(text);
console.log(text);
//var url = 'https://translate.google.com/translate_tts?&ie=utf-8&tl=zh-CN&q=' + text;
var url = 'https://translate.google.com/translate_tts?ie=UTF-8&q=' + text + '&tl=en';
$('audio').attr('src', url).get(0).play();
});
});
</script>
HTML:
<input type="text" name="text">
<a href="#" class="say">Say it</a>
<audio src="" class="speech" hidden></audio>

正如你在这个小提琴中看到的那样 - http://jsfiddle.net/patridge/h4Lvp/,
您可以通过调用setRequestHeader
来覆盖标头值。
但是,某些标题会被浏览器阻止过度使用。
/*global jQuery*/
(function ($) {
$.ajaxSetup({
"beforeSend": function(xhr) {
// Works fine.
xhr.setRequestHeader("X-Requested-With", {
toString: function() {
return "";
}
});
// Logs error on Chrome (probably others) as "Refused to set unsafe header "Referer".
xhr.setRequestHeader("Referer", {
toString: function() {
return "";
}
});
}
});
}(jQuery));
jQuery(function () {
$.ajax({
url: "http://fiddle.jshell.net/",
dataType: "html"
}).done(function (data) {
$("<div>").text("ajax success").appendTo("body");
});
});

为什么您的PHP脚本失败:
如果您看一下PHP的错误响应:
PHP Warning: file_get_contents(https://translate.google.com/translate_tts?ie=utf-8&q=the+brown+fox+jumped+over+the+lazy+dog)
您会注意到file_get_contents
请求的网址不包含tl
参数。这导致返回404。您可以直接在浏览器中访问该页面:
https://translate.google.com/translate_tts?ie=utf-8&q=the+brown+fox+jumped+over+the+lazy+dog
以上返回404响应:(
https://translate.google.com/translate_tts?ie=utf-8&q=the+brown+fox+jumped+over+the+lazy+dog&tl=en
但是在我们添加了一个漂亮的新闪亮tl=en
参数后,它可以工作:)。
