请求Google文字转语音API [英] Request to Google Text-To-Speech API

问题描述

我有这个网址： http://translate.google.com/translate_tts?ie=utf-8&tl=en&q=Hello+world
当我将它放到浏览器的地址栏中并按下回车键时，我会收到带有合成语音的MP3文件，内容为Hello world。一切都是正确的。

但现在我有一个HTML链接重定向到这个URL，像这样：

 < a href =http://translate.google.com/translate_tts?ie=utf-8&tl=en&q=Hello+world>连结< / a> ; 
  

当我点击这个链接时，我没有收到一个文件，而是一个错误（简单的QuickTime标志） 。任何人都可以解释我为什么这样，我该如何解决我的问题？

解决方案

解释是Google限制了此服务：根据此StackOverflow答案，如果HTTP请求包含 Referer header

当你键入地址栏中的网址，因为没有Referer网址传送给Google，所以没关系。当你点击一个超链接时，你有一个引用者，Google会阻止你的请求。

注意：我测试了你的URL（参见这里），并且工作。我怀疑这只是因为我之前通过在地址栏中键入URL来尝试，而资源仍然在我的浏览器缓存或音频插件（VLC）缓存中。

NB2：请参阅此处 a>解决方法。

I have this URL: http://translate.google.com/translate_tts?ie=utf-8&tl=en&q=Hello+world When I put it to the address bar in a browser and hit enter, I get mp3 file with synthesized speech saying "Hello world". Everything is correct.

But now I have a link in HTML that redirects to this URL, like this:

<a href="http://translate.google.com/translate_tts?ie=utf-8&tl=en&q=Hello+world">Link</a>

When I click this link, I don't get a file but an error (simple QuickTime logo). Could anyone explain me why is it so and how can I solve my problem?

解决方案

The explanation is that Google restricts the usage of this service: according to this StackOverflow answer, Google returns a 404 error if the HTTP request contains a Referer header other than an empty string.

When you type the URL in the address bar, it's ok because no Referer URL is transmitted to Google. When you click on a hyperlink, you have a referer and Google blocks your request.

NB: I tested your URL (see here), and it worked. I suspect that it was only because I have tried before by typing the URL in my address bar, and the resource was still in my browser cache or in my audio plugin (VLC) cache.
