1 服務器接口簡介
此處我使用的服務器接口是使用Flask編寫，具體實現代碼：
# -*- coding: utf-8 -*- from flask import Flask, render_template, jsonify, request import time import os import base64 app = Flask(__name__) UPLOAD_FOLDER= ‘E:\myupload\picture‘ app.config[‘UPLOAD_FOLDER‘] = UPLOAD_FOLDER basedir = os.path.abspath(os.path.dirname(__file__)) ALLOWED_EXTENSIONS = set([‘txt‘, ‘png‘, ‘jpg‘, ‘xls‘, ‘JPG‘, ‘PNG‘, ‘xlsx‘, ‘gif‘, ‘GIF‘,‘mp4‘]) # 用於判斷文件後綴 def allowed_file(filename): return ‘.‘ in filename and filename.rsplit(‘.‘, 1)[1] in ALLOWED_EXTENSIONS # 上傳文件 @app.route(‘/api/upload‘, methods=[‘POST‘], strict_slashes=False) def api_upload(): file_dir = os.path.join(basedir, app.config[‘UPLOAD_FOLDER‘]) if not os.path.exists(file_dir): os.makedirs(file_dir) f = request.files[‘myfile‘] # 從表單的file字段獲取文件，myfile為該表單的name值if f and allowed_file(f.filename): # 判斷是否是允許上傳的文件類型 fname = f.filename print fname ext = fname.rsplit(‘.‘, 1)[1] # 獲取文件後綴 unix_time = int(time.time()) new_filename = str(unix_time) + ‘.‘ + ext # 修改了上傳的文件名 f.save(os.path.join(file_dir, new_filename)) # 保存文件到upload目錄 print new_filename token = base64.b64encode(new_filename) print token return jsonify({"errno": 0, "errmsg": "上傳成功", "token": token}) else: return jsonify({"errno": 1001, "errmsg": "上傳失敗"}) if __name__ == ‘__main__‘: app.run(debug=True)

2 Android端代碼實現
代碼分三部分：
分別是xml布局文件，Activity類，和Okhttp網絡通信類。
2.1 xml布局文件
activity_video_upload.xml：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <LinearLayout android:layout_width="wrap_content" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_height="60dp" android:layout_marginTop="80dp" android:orientation="horizontal"> <TextView android:layout_width="match_parent" android:layout_height="50dp" android:layout_gravity="center_vertical" android:gravity="center" android:text="視頻名稱：" android:textColor="@color/black2" android:textSize="18dp"/> <EditText android:id="@+id/upload_video_name" android:layout_width="280dp" android:layout_height="50dp" android:layout_gravity="center_vertical" android:hint="請輸入上傳視頻名稱" android:layout_marginLeft="5dp" android:textSize="18dp" /> </LinearLayout> <Button android:id="@+id/video_select" android:layout_width="match_parent" android:layout_height="44dp" android:layout_marginLeft="100dp" android:layout_marginRight="100dp" android:layout_marginTop="80dp" android:background="@drawable/exit_btn_blue" android:text="選擇視頻" android:textStyle="bold" android:textColor="@android:color/white" android:textSize="20sp"/> <Button android:id="@+id/video_upload" android:layout_width="match_parent" android:layout_height="44dp" android:layout_marginLeft="100dp" android:layout_marginRight="100dp" android:layout_marginTop="40dp" android:background="@drawable/exit_btn_blue" android:text="點擊上傳" android:textStyle="bold" android:textColor="@android:color/white" android:textSize="20sp"/> <TextView android:id="@+id/post_text" android:layout_marginTop="40dp" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:text="0" /> <ProgressBar android:id="@+id/post_progress" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" style="?android:attr/progressBarStyleHorizontal" android:layout_width="match_parent" android:layout_height="wrap_content" android:max="100" /> </LinearLayout>

Cursor cur = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new String[] { MediaStore.Images.ImageColumns._ID }, buff.toString(), null, null); int index = 0; for (cur.moveToFirst(); !cur.isAfterLast(); cur.moveToNext()) { index = cur.getColumnIndex(MediaStore.Images.ImageColumns._ID); // set _id value index = cur.getInt(index); } if (index == 0) { // do nothing } else { Uri uri_temp = Uri .parse("content://media/external/images/media/" + index); if (uri_temp != null) { uri = uri_temp; Log.i("urishi", uri.toString()); } } } } return uri; } private String getPath(Uri uri) { String[] projection = {MediaStore.Video.Media.DATA}; Cursor cursor = managedQuery(uri, projection, null, null, null); int column_index = cursor .getColumnIndexOrThrow(MediaStore.Video.Media.DATA); cursor.moveToFirst(); return cursor.getString(column_index); } }
2.3 Okhttp網絡通信類
HttpUtil類：
package com.liu.dance.util; import android.util.Log; import java.io.File; import java.util.concurrent.TimeUnit; import okhttp3.MediaType; import okhttp3.MultipartBody; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.RequestBody; /** * Created by 舞動的心 on 2018/3/5. */ public class HttpUtil { private static OkHttpClient okHttpClient = new OkHttpClient.Builder().connectTimeout(10000, TimeUnit.MILLISECONDS) .readTimeout(10000,TimeUnit.MILLISECONDS) .writeTimeout(10000, TimeUnit.MILLISECONDS).build(); public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8"); public static final MediaType MEDIA_TYPE_MARKDOWN = MediaType.parse("text/x-markdown; charset=utf-8");public static void postFile(String url, final ProgressListener listener, okhttp3.Callback callback, File...files){ MultipartBody.Builder builder = new MultipartBody.Builder(); builder.setType(MultipartBody.FORM); Log.i("huang","files[0].getName()=="+files[0].getName()); //第一個參數要與Servlet中的一致 builder.addFormDataPart("myfile",files[0].getName(), RequestBody.create(MediaType.parse("application/octet-stream"),files[0])); MultipartBody multipartBody = builder.build(); Request request = new Request.Builder().url(url).post(new ProgressRequestBody(multipartBody,listener)).build(); okHttpClient.newCall(request).enqueue(callback); } }
ProgressListener接口：
package com.liu.dance.util; /** * Created by 舞動的心 on 2018/3/8. */ public interface ProgressListener { void onProgress(long currentBytes, long contentLength, boolean done); }
ProgressModel類：
package com.liu.dance.util; import android.os.Parcel; import android.os.Parcelable; /** * Created by 舞動的心 on 2018/3/8. */ public class ProgressModel implements Parcelable { private long currentBytes; private long contentLength; private boolean done = false; public ProgressModel(long currentBytes, long contentLength, boolean done) { this.currentBytes = currentBytes; this.contentLength = contentLength; this.done = done; } public long getCurrentBytes() { return currentBytes; } public void setCurrentBytes(long currentBytes) { this.currentBytes = currentBytes; } public long getContentLength() { return contentLength; } public void setContentLength(long contentLength) { this.contentLength = contentLength; } public boolean isDone() { return done; } public void setDone(boolean done) { this.done = done; } private static final Creator<ProgressModel> CREATOR = new Creator<ProgressModel>() { @Override public ProgressModel createFromParcel(Parcel parcel) { return new ProgressModel(parcel); } @Override public ProgressModel[] newArray(int i) { return new ProgressModel[i]; } }; @Override public int describeContents() { return 0; } @Override public void writeToParcel(Parcel parcel, int i) { parcel.writeLong(currentBytes); parcel.writeLong(contentLength); parcel.writeByte((byte) (done==true?1:0)); } protected ProgressModel(Parcel parcel) { currentBytes = parcel.readLong(); contentLength = parcel.readLong(); done = parcel.readByte()!=0; } }
ProgressRequestBody類：
package com.liu.dance.util; import android.os.Handler; import android.os.Looper; import android.os.Message; import java.io.IOException; import okhttp3.MediaType; import okhttp3.RequestBody; import okio.Buffer; import okio.BufferedSink; import okio.ForwardingSink; import okio.Okio; import okio.Sink; /** * Created by 舞動的心 on 2018/3/8. */ public class ProgressRequestBody extends RequestBody { public static final int UPDATE = 0x01; private RequestBody requestBody; private ProgressListener mListener; private BufferedSink bufferedSink; private MyHandler myHandler; public ProgressRequestBody(RequestBody body, ProgressListener listener) { requestBody = body; mListener = listener; if (myHandler==null){ myHandler = new MyHandler(); } } class MyHandler extends Handler { public MyHandler() { super(Looper.getMainLooper()); } @Override public void handleMessage(Message msg) { switch (msg.what){ case UPDATE: ProgressModel progressModel = (ProgressModel) msg.obj; if (mListener!=null)mListener.onProgress(progressModel.getCurrentBytes(),progressModel.getContentLength(),progressModel.isDone()); break; } } } @Override public MediaType contentType() { return requestBody.contentType(); } @Override public long contentLength() throws IOException { return requestBody.contentLength(); } @Override public void writeTo(BufferedSink sink) throws IOException { if (bufferedSink==null){ bufferedSink = Okio.buffer(sink(sink)); } //寫入 requestBody.writeTo(bufferedSink); //刷新 bufferedSink.flush(); } private Sink sink(BufferedSink sink) { return new ForwardingSink(sink) { long bytesWritten = 0L; long contentLength = 0L; @Override public void write(Buffer source, long byteCount) throws IOException { super.write(source, byteCount); if (contentLength==0){ contentLength = contentLength(); } bytesWritten += byteCount; //回調 Message msg = Message.obtain(); msg.what = UPDATE; msg.obj = new ProgressModel(bytesWritten,contentLength,bytesWritten==contentLength); myHandler.sendMessage(msg); } }; } }
