[英]use apache-httpClient, getResponseBodyAsStream result is not the same
我使用httpClient3.1。 我認為雖然length buffer.length
然后a.txt包含所有內容。 但這不是。 使用getMethod.getResponseBodyAsStream
之前,使用getMethod.getResponseBodyAsString.everything
。 getMethod.getResponseBodyAsString.everything
都很好。 例如
public static void testGetResponseBodyAsStream() throws HttpException, IOException{
/*test stackoverflow.com*/
String uri="http://www.stackoverflow.com";
/*uses httpClient 3.1*/
HttpClient httpClient=new HttpClient();
GetMethod getMethod=new GetMethod(uri);
httpClient.executeMethod(getMethod);
/*get result write file */
FileOutputStream fileOutputStream=new FileOutputStream(new File("c:/a.txt"));
/*buffer is Large enough*/
byte[] buffer=new byte[1024*1024];
BufferedInputStream bufferedInputStream=new BufferedInputStream(getMethod.getResponseBodyAsStream());
/*While length<buffer.length then a.txt contains all of
content.But it's no.
Before uses getMethod.getResponseBodyAsStream, uses
getMethod.getResponseBodyAsString.everything is good . */
int length=bufferedInputStream.read(buffer,0,buffer.length);
fileOutputStream.write(buffer, 0, buffer.length);
fileOutputStream.close();
}
嘗試此操作,看來您可能未調用某些所需的方法:
String url = "https://login.yahoo.com";
String _strGetRspBody;
String _strPostRspBody;
int port = 443;
HttpClient httpClient = new HttpClient(new MultiThreadedHttpConnectionManager());
httpClient.getHostConfiguration().setHost(url, port, "https");
GetMethod authget = new GetMethod(url);
try {
httpClient.executeMethod(authget);
} catch (IOException i) {
logger.error(i.toString());
}
InputStream d = authget.getResponseBodyAsStream();
