public static String newPost(String actionUrl, Map<String, String> params,String imagepath) { String code = "0"; Log.i("http", actionUrl); HttpParams httpParameters = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout(httpParameters, 1000*30); HttpConnectionParams.setSoTimeout(httpParameters, 1000*30); HttpConnectionParams.setTcpNoDelay(httpParameters, true); HttpClient httpclient = new DefaultHttpClient(httpParameters); HttpPost httppost = new HttpPost(actionUrl); MultipartEntity mpEntity = new MultipartEntity(); try { File imageFile = new File(imagepath); if(!imageFile.exists()) { Log.i("http", "999"); code = "999"; } for (Map.Entry<String, String> entry : params.entrySet()) { String key = entry.getKey().toString(); String value = entry.getValue().toString(); Log.i("Http","KEY:" + key + ",Value:" + value ); mpEntity.addPart(key, new StringBody(value)); } FileBody file = new FileBody(imageFile); mpEntity.addPart("name", file); httppost.setEntity(mpEntity); HttpResponse response = httpclient.execute(httppost); if (response.getStatusLine().getStatusCode() == 200) { code = EntityUtils.toString(response.getEntity()); System.out.println("result:" + code); Log.i("http", code); } } catch (Exception e) { return code; } return code; } 这个是我昨天刚写的，可用。
需要用到2个jar包，httpmime-4.0.jar，apache-mime4j-0.6.jar
还有一种是
Java code?public static String post(String actionUrl, Map<String, String> params, Map<String, File> files) throws IOException { StringBuilder sb2 = new StringBuilder(); String BOUNDARY = java.util.UUID.randomUUID().toString(); String PREFIX = "--", LINEND = "\r\n"; String MULTIPART_FROM_DATA = "multipart/form-data"; String CHARSET = "UTF-8"; URL uri = new URL(actionUrl); HttpURLConnection conn = (HttpURLConnection) uri.openConnection(); conn.setReadTimeout(5 * 1000); conn.setDoInput(true); conn.setDoOutput(true); conn.setUseCaches(false); conn.setRequestMethod("POST"); conn.setRequestProperty("connection", "keep-alive"); conn.setRequestProperty("Charsert", "UTF-8"); conn.setRequestProperty("Content-Type", MULTIPART_FROM_DATA + ";boundary=" + BOUNDARY); StringBuilder sb = new StringBuilder(); for (Map.Entry<String, String> entry : params.entrySet()) { sb.append(PREFIX); sb.append(BOUNDARY); sb.append(LINEND); sb.append("Content-Disposition: form-data; name=\"" + entry.getKey() + "\"" + LINEND); sb.append("Content-Type: text/plain; charset=" + CHARSET + LINEND); sb.append("Content-Transfer-Encoding: 8bit" + LINEND); sb.append(LINEND); sb.append(entry.getValue()); sb.append(LINEND); } DataOutputStream outStream = new DataOutputStream( conn.getOutputStream()); outStream.write(sb.toString().getBytes()); if (files != null) { // int i = 0; for (Map.Entry<String, File> file : files.entrySet()) { StringBuilder sb1 = new StringBuilder(); sb1.append(PREFIX); sb1.append(BOUNDARY); sb1.append(LINEND); // sb1.append("Content-Disposition: form-data; name=\"file"+(i++)+"\"; filename=\""+file.getKey()+"\""+LINEND); sb1.append("Content-Disposition: form-data; name=\"userupfile\"; filename=\"" + file.getKey() + "\"" + LINEND); sb1.append("Content-Type: application/octet-stream; charset=" + CHARSET + LINEND); sb1.append(LINEND); outStream.write(sb1.toString().getBytes()); InputStream is = new FileInputStream(file.getValue()); byte[] buffer = new byte[1024]; int len = 0; while ((len = is.read(buffer)) != -1) { outStream.write(buffer, 0, len); } is.close(); outStream.write(LINEND.getBytes()); } } byte[] end_data = (PREFIX + BOUNDARY + PREFIX + LINEND).getBytes(); outStream.write(end_data); outStream.flush(); int res = conn.getResponseCode(); InputStream in = null; if (res == 200) { in = conn.getInputStream(); int ch; while ((ch = in.read()) != -1) { sb2.append((char) ch); } Log.i("CAMERA", sb2.toString()); } return in == null ? null : sb2.toString(); } 上一页 [1] [2]
