マルチパートフォームデータと画像をAndroidのサーバーにアップロードする方法は？
Android codeでサーバーにマルチパートエンティティイメージをアップロード中のステータスコード500
Html形式：（サーバーに正常に画像を追加できます）
<form method="post" action="http://xyz/upload_picture" enctype="multipart/form-data">
Sample Picture Upload Form Submit
<br/><br/>
API key: <input type="text" name="key" value="abc"><br/><br/>
Login: <input type="text" name="login" value="text"><br/>
Password: <input type="password" name="password" value="text"><br/><br/>
Property ID:<input type="text" name="property_id" value="111"><br/>
Picture File:<input type="file" name="picture"><br/><br/>
<br/><br/>
<input type="submit" name="" value="Upload Picture"><br/>
</form>
Androidコード：（ステータスコード500を返します）
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://xyz/upload_picture");
try {
MultipartEntity entity = new MultipartEntity();
entity.addPart("key", new StringBody("abc"));
entity.addPart("login", new StringBody("abc"));
entity.addPart("password", new StringBody("test"));
entity.addPart("property_id", new StringBody("111"));
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DCIM).toString()
+ "/Camera/Test.jpg");
entity.addPart("picture", new FileBody(file));
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
Log.e("test", "SC:" + response.getStatusLine().getStatusCode());
HttpEntity resEntity = response.getEntity();
BufferedReader reader = new BufferedReader(new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
Log.e("test", "Response: " + s);
} catch (ClientProtocolException e) {

私のように、マルチパートアップロードに苦労していました。 this Android snippet。
public String multipartRequest(String urlTo, Map<String, String> parmas, String filepath, String filefield, String fileMimeType) throws CustomException {
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
InputStream inputStream = null;
String twoHyphens = "--";
String boundary = "*****" + Long.toString(System.currentTimeMillis()) + "*****";
String lineEnd = "\r\n";
String result = "";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String[] q = filepath.split("/");
int idx = q.length - 1;
try {
File file = new File(filepath);
FileInputStream fileInputStream = new FileInputStream(file);

connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("User-Agent", "Android Multipart HTTP Client 1.0");
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
outputStream = new DataOutputStream(connection.getOutputStream());
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"" + filefield + "\"; filename=\"" + q[idx] + "\"" + lineEnd);

}
outputStream.writeBytes(lineEnd);
// Upload POST Data
Iterator<String> keys = parmas.keySet().iterator();
while (keys.hasNext()) {
String key = keys.next();
String value = parmas.get(key);
outputStream.writeBytes(twoHyphens + boundary + lineEnd);

}
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
if (200 != connection.getResponseCode()) {
throw new CustomException("Failed to upload code:" + connection.getResponseCode() + " " + connection.getResponseMessage());
}
inputStream = connection.getInputStream();
result = this.convertStreamToString(inputStream);
fileInputStream.close();
inputStream.close();
outputStream.flush();
outputStream.close();
return result;
} catch (Exception e) {
logger.error(e);
throw new CustomException(e);
}
}
private String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
呼び出しコード：
//setup params
Map<String, String> params = new HashMap<String, String>(2);
params.put("foo", hash);
params.put("bar", caption);
String result = multipartRequest(URL_UPLOAD_VIDEO, params, pathToVideoFile, "video", "video/mp4");
//next parse result string
これは、外部HTTPCoreとそのようなライブラリを使用せずに機能したソリューションです。私は64Kメソッドの問題に直面していたので、HTTPCoreライブラリを回避するオプションが残っていません

アップロードを受け入れるPHPコード

ステータスコード500は、サーバーの設定に問題があることを意味します。コードとは関係ありません。 http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html を参照してください。
これを試してみてください
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DCIM).toString()
+ "/Camera/Test.jpg");
entity.addPart("picture", new FileBody(file,"image/jpg")); //Update here
私はこの答えを投稿するのに遅れていることを知っていますが、それでも誰かがAndroidのサーバーに複数の画像をアップロードしたい場合
String uploadMultipleFiles(Api api, HashMap<String, ArrayList<File>> fileListMap)
throws IOException {
String responseS;
OkHttpClient timeOut = getOkHttpClient(api.getTimeOut());
MultipartBody.Builder multipartBuilder = new MultipartBody.Builder()
.setType(MultipartBody.FORM);
int j = 0;
ArrayList<File> fileList;
for (Map.Entry<String, ArrayList<File>> entry : fileListMap.entrySet()) {
String key = entry.getKey();
fileList = entry.getValue();
multipartBuilder.addFormDataPart("data[" + j + "].name", key);
if (fileList != null) {
for (int i = 0; i < fileList.size(); i++) {
File fileListRequest = fileList.get(i);
if (fileListRequest.exists()) {
String ext = CommonUtils.getExtension(fileListRequest.getName());
/* Changing Media Type whether JPEG or PNG **/
final MediaType MEDIA_TYPE = ext.endsWith("png") ? MEDIA_TYPE_PNG :
ext.endsWith("jpg") ? MEDIA_TYPE_JPG : MEDIA_TYPE_JPEG;
multipartBuilder.addFormDataPart("data[" + j + "].files[" + i + "]",
fileListRequest.getName(),
RequestBody.create(MEDIA_TYPE, fileListRequest));
}
}
}
j++;
}
RequestBody requestBody = multipartBuilder.build();
Request.Builder requestBuilder = new Request.Builder()
.url(Objects.requireNonNull(api.getUrl()))
.post(requestBody);
buildHeaders(requestBuilder);
Response response = timeOut.newCall(requestBuilder.build()).execute();
responseS = response.body().string();
Log.i(api.getName().name(), responseS);
return responseS;
}
上記のコードは、複数の画像をサーバーにアップロードするためのものであり、単一の画像については、以下の単一行のみを追加する必要があります
multipartBuilder.addFormDataPart("fileName",fileListRequest.getName(),RequestBody create(MEDIA_TYPE,fileListRequest));
こんにちは、たくさんの検索試行錯誤の後、ついにこの友達ができました
//グラフAPIを使用して画像をFacebookにアップロードする方法について
Bundle params = new Bundle();
params.putByteArray("multipart/form-data",byteArray);
params.putString("caption",txtcaption.getText().toString());
/* make the API call */
new GraphRequest(
AccessToken.getCurrentAccessToken(),
"/me/photos",
params,
HttpMethod.POST,
new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
/* handle the result */
Log.e("responseImagedata---", response.toString());
}
}
).executeAsync();
