代码在原文的基础上增加了Transfer-Encoding的判断。

最近项目在使用 http://wthrcdn.etouch.cn/weather_mini
获取天气预报数据，但此接口只能用get方法请求，而且返回数据一直是乱码，原来返回数据用gzip格式压缩了，所以我的方

法中增加了判断是否为gzip并解压

public static String sendGet(String url) {
StringBuffer stringBuffer = new StringBuffer();
try {
URL realUrl = new URL(url);

        HttpURLConnection httpURLConnection = (HttpURLConnection) realUrl.openConnection();
//在这里设置一些属性，详细见UrlConnection文档，HttpURLConnection是UrlConnection的子类
//设置连接超时为5秒
httpURLConnection.setConnectTimeout(5000);
//设定请求方式(默认为get)
httpURLConnection.setRequestMethod("GET");
httpURLConnection.setRequestProperty("accept", "*/*");
httpURLConnection.setRequestProperty("Accept-Charset", "UTF-8");
httpURLConnection.setRequestProperty("contentType", "UTF-8");
httpURLConnection.setRequestProperty("Content-type", "application/x-www-form-urlencoded;charset=UTF-8");
//建立到远程对象的实际连接
httpURLConnection.connect();
GZIPInputStream gZIPInputStream = null;
String encoding = httpURLConnection.getContentEncoding();
String TransferEncoding = httpURLConnection.getHeaderField("Transfer-Encoding");

        if((null!=encoding && encoding.equals("gzip")) || (null!=TransferEncoding && TransferEncoding.equals("chunked"))){
gZIPInputStream = new GZIPInputStream(httpURLConnection.getInputStream());
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(gZIPInputStream));
String line = null;
while ((line = bufferedReader.readLine()) != null) {
//转化为UTF-8的编码格式
line = new String(line.getBytes("UTF-8"));
stringBuffer.append(line);
}
bufferedReader.close();
}else{
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream()));
String line = null;
while ((line = bufferedReader.readLine()) != null) {
//转化为UTF-8的编码格式
line = new String(line.getBytes("UTF-8"));
stringBuffer.append(line);
}
bufferedReader.close();
}
//返回打开连接读取的输入流，输入流转化为StringBuffer类型，这一套流程要记住，常用

httpURLConnection.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return stringBuffer.toString();
}
