步骤:
Step1. 申请ApiKey,http://developer.baidu.com/console#app/project
Step2. 组成Get请求
Step3. 获得响应
Step4. 对响应进行解析(关键)
Step5. 结果输出
关键代码(C#):
public string getTraslation(string src)
{
//发送请求
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://openapi.baidu.com/public/2.0/bmt/translate?client_id="
+ client_id + "&q=" + src + "&from=" + from + "&to=" + to);
//获得响应
string res = string.Empty;
try
{
//获取响应流
HttpWebResponse response = (HttpWebResponse)myReq.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
res = reader.ReadToEnd();
reader.Close();
response.Close();
//正则表达式
string pattern = @"""dst"":""(?.*?)""}";
MatchCollection matchs;
string result = string.Empty;
matchs = Regex.Matches(res, pattern, RegexOptions.IgnoreCase | RegexOptions.Singleline);
foreach (Match m in matchs)
{
string strTokenValue = m.Groups["tokenVal"].Value;
string[] stringSeparators = new string[] { "\\u"
};
string[] unicodeArray = strTokenValue.Split(stringSeparators, StringSplitOptions.RemoveEmptyEntries);
StringBuilder sb = new StringBuilder();
if (unicodeArray.Length <= 1)
{
result = strTokenValue;
}
else
{
foreach (string item in unicodeArray)
{
byte[] codes = new byte[2];
int code1, code2;
code1 = Convert.ToInt32(item.Substring(0, 2), 16);
code2 = Convert.ToInt32(item.Substring(2), 16);
codes[0] = (byte)code2;//必须是小端在前
codes[1] = (byte)code1;
sb.Append(Encoding.Unicode.GetString(codes));
}
result = sb.ToString();
}
}
return result;
}
catch (Exception)
{
return null;
}
}
关键代码(Java):
public String getResult(String input){
try {
String src = URLEncoder.encode(input,"utf-8");
httpGet = new HttpGet("http://openapi.baidu.com/public/2.0/bmt/translate?client_id="+client_id+"&q="+src+"&from="+from+"&to="+to);
httpResponse = httpClient.execute(httpGet);
httpEntity = httpResponse.getEntity();
String content = EntityUtils.toString(httpEntity, "utf-8");
Matcher matcher = Pattern.compile("\"dst\":\"(?.*?)\"}").matcher(content);
if (matcher.find()){
strTokenValue = matcher.group("tokenVal");
String[] sarray = strTokenValue.split("\\\\u");
if (sarray.length <= 1){
result = strTokenValue;
}
else {
mybyte = new byte[2*sarray.length-2];
for (int i = 0; i < sarray.length-1; i++){
mybyte[2*i] = (byte)Integer.parseInt(sarray[i+1].substring(0, 2), 16);
mybyte[2*i+1] = (byte)Integer.parseInt(sarray[i+1].substring(2, 4), 16);
}
result = new String(mybyte,"utf-16");
}
}
httpGet.abort();
return result;
} catch (Exception e) {
return null;
}
}
