使用Microsoft Translator API使用C#翻译整个网页

使用C#将带有Microsoft Translator API(SOAP)的网页翻译。我想翻译我的网站,但使用翻译小工具对我不好,因为我需要谷歌抓取我的翻译页面。所以我需要在将其发送到浏览器之前进行翻译。

到目前为止还没有API(我试过找到它,我不能,如果你碰巧知道一个请提及),你可以传递一个网址,它会发送给你翻译的响应:{{3 }}

这些是我迄今为止所做的尝试: 1.从Url下载字符串,传递给Client.Translate(..)。

  

格式化程序在尝试反序列化时抛出异常   消息:反序列化操作的请求消息正文时出错   '翻译'。已经有最大字符串内容长度配额(30720)   读取XML数据时超出了这个配额可能会增加   更改了MaxStringContentLength属性   创建XML阅读器时使用的XmlDictionaryReaderQuotas对象。   第516行,第48位。

private static void processDocument(HtmlAgilityPack.HtmlDocument html, LanguageServiceClient Client)
        {
            HtmlNodeCollection coll = html.DocumentNode.SelectNodes("//text()[normalize-space(.) != '']");
            foreach (HtmlNode node in coll)
            {
                if (node.InnerText == node.InnerHtml)
                {
                    //node.InnerHtml = translateText(node.InnerText);
                    node.InnerHtml = Client.Translate("", node.InnerText, "en", "fr", "text/html", "general");
                }
            }

        }

这一次占用了太多时间。最后我得到了一个Bad request(400)异常。

解决这个问题的最佳方法是什么?我还计划保存文档,以便我不必每次都进行翻译。

此C#示例从本地文件转换HTML:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using HtmlAgilityPack;

namespace TranslationAssistant.Business
{
class HTMLTranslationManager
{
    public static int DoTranslation(string htmlfilename, string fromlanguage, string tolanguage)
    {
        string htmldocument = File.ReadAllText(htmlfilename);
        string htmlout = string.Empty;

        HtmlDocument htmlDoc = new HtmlDocument();
        htmlDoc.LoadHtml(htmldocument);
        htmlDoc.DocumentNode.SetAttributeValue("lang", TranslationServices.Core.TranslationServiceFacade.LanguageNameToLanguageCode(tolanguage));
        var title = htmlDoc.DocumentNode.SelectSingleNode("//head//title");
        if (title != null) title.InnerHtml = TranslationServices.Core.TranslationServiceFacade.TranslateString(title.InnerHtml, fromlanguage, tolanguage, "text/html");
        var body = htmlDoc.DocumentNode.SelectSingleNode("//body");
        if (body != null)
        {
            if (body.InnerHtml.Length < 10000)
            {
                body.InnerHtml = TranslationServices.Core.TranslationServiceFacade.TranslateString(body.InnerHtml, fromlanguage, tolanguage, "text/html");
            }
            else
            {
                List<HtmlNode> nodes = new List<HtmlNode>();
                AddNodes(body.FirstChild, ref nodes);

                Parallel.ForEach(nodes, (node) =>
                    {
                        if (node.InnerHtml.Length > 10000)
                        {
                            throw new Exception("Child node with a length of more than 10000 characters encountered.");
                        }
                        node.InnerHtml = TranslationServices.Core.TranslationServiceFacade.TranslateString(node.InnerHtml, fromlanguage, tolanguage, "text/html");
                    });
            }
        }
        htmlDoc.Save(htmlfilename, Encoding.UTF8);
        return 1;
    }

    /// <summary>
    /// Add nodes of size smaller than 10000 characters to the list, and recurse into the bigger ones.
    /// </summary>
    /// <param name="rootnode">The node to start from</param>
    /// <param name="nodes">Reference to the node list</param>
    private static void AddNodes(HtmlNode rootnode, ref List<HtmlNode> nodes)
    {
        string[] DNTList = { "script", "#text", "code", "col", "colgroup", "embed", "em", "#comment", "image", "map", "media", "meta", "source", "xml"};  //DNT - Do Not Translate - these nodes are skipped.
        HtmlNode child = rootnode;
        while (child != rootnode.LastChild)
        {
            if (!DNTList.Contains(child.Name.ToLowerInvariant())) {
                if (child.InnerHtml.Length > 10000)
                {
                    AddNodes(child.FirstChild, ref nodes);
                }
                else
                {
                    if (child.InnerHtml.Trim().Length != 0) nodes.Add(child);
                }
            }
            child = child.NextSibling;
        }
    }

}
}

这是http://github.com/microsofttranslator/documenttranslator中的HTMLTranslationManager.cs,它使用TranslationServiceFacade.cs中的辅助函数TranslateString()。您可以简化并在此处插入翻译服务调用来代替TranslateString()。
