Question

httpclient 如何传字节

Answer 1

public String post(String pathToOurFile,String urlServer) throws ClientProtocolException, IOException {
HttpClient httpclient = new DefaultHttpClient();

//String pathToOurFile = "abc.txt"; //uploadfile
//String urlServer = "http://192.168.1.2/upload.action";

HttpPost httppost = new HttpPost(urlServer);
File file = new File(pathToOurFile);

MultipartEntity mpEntity = new MultipartEntity(); //文件传输
ContentBody cbFile = new FileBody(file);
mpEntity.addPart("userfile", cbFile); // <input type="file" name="userfile" /> 对应的

httppost.setEntity(mpEntity);
System.out.println("executing request " + httppost.getRequestLine());

HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();

System.out.println(response.getStatusLine());//通信Ok
String responseStr=EntityUtils.toString(resEntity,"utf-8");
System.out.println(resEntity );
resEntity.consumeContent();

httpclient.getConnectionManager().shutdown();
return responseStr;
}
