Asp.NET调用百度翻译的方法

时间：2021-05-28

本文实例讲述了Asp.NET调用百度翻译的方法。分享给大家供大家参考。具体分析如下：

Asp.NET调用百度翻译，如下图所示：

HTML代码如下:

复制代码 代码如下:<%@ Page Language="C#" AutoEventWireup="true" CodeFile="baidu.aspx.cs" Inherits="FanYi_baidu" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http:///public/2.0/bmt/translate";
string requestDetail = "client_id=申请的ID";
protected void Page_Load(object sender, EventArgs e)
{

}
[DataContract]
public class AdmAccessToken
{
[DataMember]
public string from { get; set; }
[DataMember]
public string to { get; set; }
[DataMember]
public string error_code { get; set; }
[DataMember]
public string error_msg { get; set; }
[DataMember]
public string query { get; set; }
[DataMember]
public List<TokenResult> trans_result { get; set; }
}

[DataContract]
public class TokenResult
{
[DataMember]
public string src { get; set; }
[DataMember]
public string dst { get; set; }
}

//百度翻译返回数据结构
//{
//"from": "en",
//"to": "zh",
//"trans_result": [
// {
// "src": "today",
// "dst": "今天"
// },
// {
// "src": "tomorrow",
// "dst": "明天"
// }
//],
//"error_code": "52001",
//"error_msg": "TIMEOUT",
//"query": "he's"
//}

/// <summary>
/// 采用Post方式提交数据
/// </summary>
/// <param name="DatamarketAccessUri">目标网址</param>
/// <param name="requestDetails">参数字符串</param>
/// <returns></returns>
private AdmAccessToken HttpPost(string DatamarketAccessUri, string requestDetails)
{
//Prepare OAuth request
WebRequest webRequest = WebRequest.Create(DatamarketAccessUri);
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(requestDetails);
webRequest.ContentLength = bytes.Length;
using (Stream outputStream = webRequest.GetRequestStream())
{
outputStream.Write(bytes, 0, bytes.Length);
}
using (WebResponse webResponse = webRequest.GetResponse())
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(AdmAccessToken));
//Get deserialized object from JSON stream
AdmAccessToken token = (AdmAccessToken)serializer.ReadObject(webResponse.GetResponseStream());
return token;
}
}

protected void Translate_Click(object sender, EventArgs e)
{
resultText.Text = "";
if (sourceWord.Text.Trim() != "")
{
string requestStr = requestDetail + "&from=" + ddlFrom.SelectedValue
+ "&to=" + ddlTo.SelectedValue
+ "&q=" + HttpUtility.UrlEncode(sourceWord.Text);

AdmAccessToken token = HttpPost(url, requestStr);
if (token.error_code != null)
{
resultText.Text = token.error_msg;
}
else
{
int n = token.trans_result.Count;
for (int i = 0; i < n; i++)
{
resultText.Text += token.trans_result[i].dst + (i < n-1 ? "\n" : "");
}
}
}
else
{
resultText.Text = "请输入要翻译的内容";
}
}
}

希望本文所述对大家的C#程序设计有所帮助。
