直接读取文件流的方式
HttpClient httpClient = new DefaultHttpClient();
String reqStr = new JSONUtil<String, ReasonsForDissatisfactionReqBean>().ObjectToJsonStr(commonRequestBean);
String paramImg = URLEncoder.encode(ContentAesQos.getParamImg(reqStr));
String url = CommonQos.NOSATISFACTION_IMG_QUERY+"?reqParam="+paramImg;
System.out.println("url:"+url);
//第二步：生成使用POST方法的请求对象
HttpGet httpPost = new HttpGet(url);
httpPost.addHeader("Content-Type", "application/json");
// String reqStr = new JSONUtil<String, ReasonsForDissatisfactionReqBean>().ObjectToJsonStr(commonRequestBean);
// String paramImg = ContentAesQos.getParamImg(reqStr);
// httpPost.setEntity(new StringEntity(paramImg));
//执行请求对象
try {
//第三步：执行请求对象，获取服务器发还的相应对象
HttpResponse response = httpClient.execute(httpPost);
//第四步：检查相应的状态是否正常：检查状态码的值是200表示正常
Log.e("HTTP", response.getStatusLine().getStatusCode() + "");
if (response.getStatusLine().getStatusCode() == 200) {
//第五步：从相应对象当中取出数据，放到entity当中
filePath = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/" + "qos_temp.png"; // 文件路径
File file = new File(filePath);
FileOutputStream outputStream = new FileOutputStream(file);
InputStream inputStream = response.getEntity()
.getContent();
byte b[] = new byte[1024];
int j = 0;
while ((j = inputStream.read(b)) != -1) {
outputStream.write(b, 0, j);
}
outputStream.flush();
outputStream.close();
// setImgView(img);
handler.sendEmptyMessage(2);
get post 都可以
