写爬虫的时候需要下载视频 遇到206问题
下载报错前的代码
try { HttpResponse resp = httpclient.execute(httpget); if (HttpStatus.SC_OK == resp.getStatusLine().getStatusCode()) { HttpEntity entity = resp.getEntity(); InputStream in = entity.getContent(); savePicToDisk(in, dirPath, fileName); logger.info("下载文件 " + fileName + " 成功...."); return true; } } catch (Exception e) { e.printStackTrace(); logger.info("下载文件 "+fileName+" 失败...."); } finally { httpclient.getConnectionManager().shutdown(); }
修改后代码
try { HttpResponse resp = httpclient.execute(httpget); if (HttpStatus.SC_OK == resp.getStatusLine().getStatusCode() || HttpStatus.SC_PARTIAL_CONTENT == resp.getStatusLine().getStatusCode()) { HttpEntity entity = resp.getEntity(); InputStream in = entity.getContent(); savePicToDisk(in, dirPath, fileName); logger.info("下载文件 " + fileName + " 成功...."); return true; } } catch (Exception e) { e.printStackTrace(); logger.info("下载文件 "+fileName+" 失败...."); } finally { httpclient.getConnectionManager().shutdown(); }
看到这里懂了吧 其实在文件下载 把206当做200一样处理就行了
似乎206是用于做文件续传 之类的 以后遇到再去研究吧……
