Microsoft Azure版本2转换CORS错误（307临时重定向“对预检的响应无效（重定向）”）

时间：2018-08-01 06:42:46

标签： azure curl cors translate

我正在尝试将V2（不建议使用）Microsoft Azure Translate与POST请求一起使用，并在开发工具网络选项卡中显示"Response for preflight is invalid (redirect)"并显示307 Temporary Redirect错误。参见屏幕截图1和2，两者都是来自WebApp Javascript的调用。

我使用CURL诊断此问题。

  1. 首先使用Curl而不使用URL [https://api.microsofttranslator.com/V2/Http.svc/GetLanguageNames?locale=en]进行预检请求。它会以有效的响应成功。

    在下面的附录A

    中查看通话和完整的答复

    一个收获是-预检请求似乎是自愿的，它使Web客户端可以知道他们的实际呼叫是否会成功。已确认-[https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#Preflighted_requests。

  2. 将URL更改为[https://api.microsofttranslator.com/V2/Http.svc/GetLanguageNames/?locale=en]（请注意查询参数之前的斜杠），并且失败并显示

     HTTP/1.1 405 Method Not Allowed
 Allow: GET

    在下面的附录B

    3. 上查看通话和完整的回复

  3. 更改为使用URL [https://api.microsofttranslator.com/V2/Http.svc/GetLanguageNames?locale=en]发送预检请求，其中包含

    HTTP/1.1 307 Temporary Redirect
Content-Length: 1997
Content-Type: text/html; charset=UTF-8
Location: https://api.microsofttranslator.com/V2/Http.svc/GetLanguageNames/?locale=en

    此响应表明，您应该改为引用其他位置。注意查询参数之前的斜杠。

    在下面的附录C

    4. 上查看通话和完整回复

  4. 在预检请求中添加-L，以强制CURL遵循重定向。它会产生与上述2相同的错误：

    HTTP/1.1 405 Method Not Allowed
Allow: GET

    在下面的附录D

    5. 中查看通话和完整的回复

鉴于所有这些，看来应用程序错误（请参见屏幕截图）等同于上面的步骤3和4。步骤3是第一个屏幕截图（进行了OPTION调用并返回了新的LOCATION）；第4步是第二个屏幕截图（重定向的OPTION位置被错误调用，并导致错误）。不幸的是，浏览器在返回有关此错误的有用信息方面表现很差。我的意思是[[https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#Preflighted_requests_and_redirects]表示“目前大多数浏览器不支持针对预检请求进行的重定向”。我以为是问题所在，但似乎正在遵循 重定向。

实际上，我正试图将其发布到[https://api.microsofttranslator.com/V2/Http.svc/TranslateArray]，尽管这也遇到了同样的问题。

现在，我已经完成了所有这些工作（其中大部分是在创建此帖子期间进行的），看来我已经解决了这个问题。因此，我的大部分问题都得到了回答。尽管要遵循SO准则，但我将发布一个问题，或者将其留在此处，以供我与Microsoft讨论时以及那些偶然发现同一问题并正在寻找答案的人参考。

我的问题是-这听起来像Microsoft的某些错误配置吗？那可能是什么？欢迎其他任何想法，建议或意见！
