HttpClient请求中HttpResponse返回乱码问题解决。

问题：EntityUtils.toString(response.getEntity()) 打印出乱码
解决：返回值数据较大时会以压缩格式返回，判断请求头中包含“gzip”，需进行特殊处理，代码如下。public static String reqGet(String url,Map headers){HttpClient client=HttpConnectionManager.getHttpClient();HttpParams params = new BasicHttpParams();String respBody="";try {HttpGet get =new HttpGet(url);Set headersSet = headers.keySet();for(String key:headersSet){get.setHeader(key, headers.get(key));}get.setParams(params);HttpClientParams.setCookiePolicy(client.getParams(), CookiePolicy.BROWSER_COMPATIBILITY);HttpResponse resp = client.execute(get);if(resp.getStatusLine().getStatusCode() == 200){respBody = getStringFromResponse(resp);}}catch (Exception e) {e.printStackTrace();}return respBody;
}

private static String getStringFromResponse(HttpResponse response) {if (response == null) {return null;}String responseText = "";try {HttpEntity entity = response.getEntity();InputStream in = entity.getContent();;Header[] headers = response.getHeaders("Content-Encoding");for (Header h : headers) {if (h.getValue().indexOf("gzip") > -1) {//For GZip responseGZIPInputStream gzin = new GZIPInputStream(in);InputStreamReader isr = new InputStreamReader(gzin, "utf-8");BufferedReader bufferedReader = new BufferedReader(isr);String lineTXT = null;while ((lineTXT = bufferedReader.readLine()) != null) {responseText += lineTXT.toString();}isr.close();break;}}if(StringUtils.isEmpty(responseText)){responseText = EntityUtils.toString(entity);}} catch (IOException exception) {exception.printStackTrace();}return responseText;
}
