【Java⾳频操作】调⽤有道词典语⾳接⼝，⽣成单词MP3⽂件，⽀持⾃定义重 复次数
参考博客：
运⾏效果
根据想要拼接的单词，⽣成⼀个单词朗读的mp3⽂件，可以⾃定义每个单词朗读时的重复次数。 代码思路：
先把要拼接的单词放进⼀个String数组中
然后遍历这个数组，⽤(伪)爬⾍下载每⼀个单词的⾳频⽂件 最后再把这些⾳频⽂件拼接起来，⽣成mp3⽂件 ↓
关于：有道词典语⾳接⼝
基于有道翻译的公共api可以制作⾃⼰的翻译app，前⼏天有这个想法，发现没有办法实现朗读功能，搜索了⼀下到了这个接⼝，解决了这个问题。⾮常简单，直接取⽹络地址进⾏播放就可以了，相当于播放⼀个⾳频⽂件，解析速度挺快。
美⾳：udao/dictvoice?type=0&audio=hello
英⾳：udao/dictvoice?type=1&audio=hello
api仅有两个参数，就是发⾳类型和单词，在audio=后⾯加上单词就ok了，type=0为美国发⾳，type=1为英国发⾳，做个程序⾃⼰⽤，⼏乎还可以吧。下⾯附上⼀个"hello"的测试，看下效果吧，第⼀个为美⾳，第⼆个为英⾳

/**

public void httpDownload()throws Exception {
public void httpDownload()throws Exception {
validate();
final String[] urls = urlString;
HttpURLConnection urlConnection;
for(int i =0; i < urls.length; i++){
urlConnection =(HttpURLConnection)new URL(urls[i])
.openConnection();
// 开启链接
InputStream inputStream = InputStream();
File temp =new File(rootDir,
String.format("%02d",i+1)+"."+targetType);
if(!ists()){
}
FileOutputStream fileOutputStream =new FileOutputStream(temp,true); int tem;
while(-1!=(tem = ad())){
fileOutputStream.write(tem);
fileOutputStream.flush();
}
fileOutputStream.close();
inputStream.close();
}
}
private void validate()throws Exception {
if(urlString.length <=0){
throw new Exception("下载路径不能为空!");
}
if(null == rootDir ||!ists()||!rootDir.isDirectory()){
throw new Exception("⽬标⽂件夹不存在!");
}
}
}
不过单线程下载速度有点慢 ，以后有空考虑下改成多线程下载
关于：⽂件的拼接（未使⽤，仅参考）
import java.io.*;
public class D3 {
public static void main(String[] args)throws Exception {
BufferedOutputStream buff=new BufferedOutputStream(new FileOutputStream("D:\\zuoye/text.mp3"));
FileInputStream int1=new FileInputStream("D:\\zuoye/太⽥美知彦 - 万⾥の长城.mp3");
FileInputStream int2=new FileInputStream("D:\\zuoye/阿桑 - 寂寞在唱歌.mp3");
//FileInputStream int3=new FileInputStream("D:\\zuoye/r.mp3");
BufferedInputStream but1=new BufferedInputStream(int1);
BufferedInputStream but2=new BufferedInputStream(int2);
//BufferedInputStream but3=new BufferedInputStream(int3);
SequenceInputStream seq1=new SequenceInputStream(but1, but2);//将两⾸歌合在⼀起
//SequenceInputStream seq2=new SequenceInputStream(seq1, but3);//将三⾸歌合在⼀起

while((ad())!=-1){

}
buff.close();
seq1.close();
//seq1.close();
