我正在使用 http api 实现必应翻译服务。我在实施过程中遇到了两个问题,经过数小时的研究,我仍然无法解决。我希望那里有人可以为我提供一些指导。
问题:
1) 发送到 web 服务的初始页面被翻译得几乎完美。但是,在呈现第一页之后,对服务器的任何后续调用都会收到来自第一个调用的响应。意味着 html 字符串已正确发送到服务,但服务返回对原始请求的原始响应,而不是对新请求的预期新响应。(服务可以缓存我的请求吗?)
2) Javascript 被翻译以及内部 html:-/ 见下面的例子:
Javascript(翻译:-/)
$(función () {}
elformulario var document.forms['ctl01 ='];
Si (typeof(Sys) == 'undefined') tira Error nuevo ('ASP NET Ajax client-side fram...

//This is the rendered HTML of your page.

outputAsString = _tsrv.Post(outputAsString, "en", "es");
writer.Write(outputAsString);

我在 vs2012 中使用默认的 webforms 模板。我可能会以错误的方式来处理这个架构,而且我之前没有尝试过实现这个服务。任何帮助是极大的赞赏!!!!
