この投稿が数年前のものであることは知っていますが、httpClientダウンロードの一部として利用可能な ここ からMultiPartEntityを使用してソリューションを共有したいと思います。バージョン4.2.5を使用しました。
私はもともと上記と同様のプロセスを使用していましたが、ビデオのアップロードのサポートを開始したときにメモリエラーが発生し始めるまではうまく機能していました。私はここでたくさんの投稿を調べて、たくさんの良いアイデアを得ました。 Java Decompiler こちらから入手可能 を使用してJarファイルのコードを調べ、物事をまとめる方法を理解しました。
//filepath is passed in like /mnt/sdcard/DCIM/100MEDIA/VIDEO0223.mp4

車輪の再発明をしないでください! ApacheHttpClientはあなたの要求を実装しました。
データを送信するAndroid JSONHttpClient PHP HttpResponseを使用するサーバー
グーグル運!
これは、MultipartEntityを使用して画像とJSONArrayをアップロードする例です--lib:org.Apache.http.entity.mime
List <Entity> students = getStudentList();
MultipartEntity studentList = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
for(int i=0; i<students.size();i++){
try {
studentList.addPart("studentList[][name]", new StringBody(String.valueOf(students.get(i).getName())));
studentList.addPart("studentList[][addmission_no]", new StringBody(String.valueOf(students.get(i).getAddmissionNo)));
studentList.addPart("studentList[][gender]", new StringBody(String.valueOf(students.get(i).getGender)));
File photoImg = new File(students.get(i).getImagePath());
studentList.addPart("studentList[][photo]",new FileBody(photoImg,"image/jpeg"));
}catch(Exception e){
e.getMessage();
}
}
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(URL);
post.addHeader("X-Auth-Token", mUserToken);
post.setEntity(studentList);
org.Apache.http.HttpResponse response = null;
try {
response = client.execute(post);
} catch (IOException e) {
e.printStackTrace();
}
HttpEntity httpEntity = response.getEntity();
JSONObject myObject;
try {
String result = EntityUtils.toString(httpEntity);
// do your work
} catch (IOException e) {
e.printStackTrace();
}
このコードを試してみるのは簡単です
public String postAsync(String url, String action, JSONObject jsonObject, String fileUri) throws JSONException {
String result = "";
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
entityBuilder.setMode(HttpMultipartMode.STRICT);
File file = new File(fileUri);
entityBuilder.addPart("file", new FileBody(file));
entityBuilder.addTextBody(DMConstant.ACTION_JSON, action);
entityBuilder.addTextBody(DMConstant.DATA_JSON, jsonObject.toString(), ContentType.create("application/json", Consts.UTF_8));
HttpEntity entity = entityBuilder.build();
httpPost.setEntity(entity);
HttpResponse httpResponse = httpClient.execute(httpPost);
InputStream inputStream = httpResponse.getEntity().getContent();
if (inputStream != null) {
result = dmUtils.convertStreamToString(inputStream);
} else {
Log.i("Input Stream is Null", "Input Stream is Null");
}
} catch (UnsupportedEncodingException e) {
Log.e("Unsupported Encoding", e.getMessage());
} catch (ClientProtocolException e) {
Log.e("Client Protocol", e.getMessage());
} catch (IOException e) {
Log.e("IOException", e.getMessage());
}
Log.i("JSON Object as Response", result);
return result;
}
........
JSONObject urlObject = new JSONObject();
urlObject.put("userName", "user name");
urlObject.put("email_id", "ä[email protected]");
urlObject.put("user_pass", "123456");
postAsync(URL, "php function name", urlObject, imageFile);
