Bing翻译服务返回对每个请求的第一个响应

我正在使用http api实现Bing翻译服务。我在实施中遇到了两个问题,经过数小时的研究后,我仍然无法解决。我希望那里的人可以给我一些指导。

问题:

1)发送到Web服务的初始页面几乎完美地翻译。但是,在呈现第一页之后,对服务器的任何后续调用都会从第一次调用接收响应。意思是html字符串正确地发送到服务,但服务返回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 ='];

namespace TestTranslation

    public class CustomPage: Page

        private TranslationService _tsrv = new TranslationService();

        protected override void Render(HtmlTextWriter writer)
        {
            using (StringWriter output = new StringWriter())
            {
                base.Render(new HtmlTextWriter(output));
                //This is the rendered HTML of your page.
                string outputAsString = output.ToString();
                outputAsString = _tsrv.Post(outputAsString, "en", "es");
                writer.Write(outputAsString);
                output.Close();
                writer.Close();
                writer.Dispose();
            }            
        }
    }
}

我在vs2012中使用默认的webforms模板。我可能会以错误的方式进行这种体系结构,以及之前我没有尝试过实现此服务。非常感谢任何帮助!!!!

1 个答案:

答案 0 :(得分:0)

我已经解决了下面解释的这些问题:

1)尝试使用各种数据将配置对象属性重新分配给自己是我自己的错。这会将我的配置文件设置为保留先前服务调用的数据。导致它解析相同的数据并将其作为新数据返回。

2)我的信念是,当传递格式错误的html脚本标签时会被翻译。另请注意,在您的Web服务调用配置中,您的内容类型参数应设置为“text / html”

希望这可以帮助有人在路上。

谢谢!
