1 服务器接口简介

此处我使用的服务器接口是使用Flask编写，具体实现代码：

 

# -*- coding: utf-8 -*-
from flask import Flask, render_template, jsonify, request
import time
import os
import base64

app = Flask(__name__)
UPLOAD_FOLDER = 'E:myuploadpicture'
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'])


# 用于判断文件后缀
def allowed_file(filename):
    return '.' in filename and filename.rsplit('.', 1)[1] in ALLOWED_EXTENSIONS


# 上传文件
@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']  # 从表单的file字段获取文件，myfile为该表单的name值
    if f and allowed_file(f.filename):  # 判断是否是允许上传的文件类型
        fname = f.filename
        print fname
        ext = fname.rsplit('.', 1)[1]  # 获取文件后缀
        unix_time = int(time.time())
        new_filename = str(unix_time) + '.' + ext  # 修改了上传的文件名
        f.save(os.path.join(file_dir, new_filename))  # 保存文件到upload目录
        print new_filename
        token = base64.b64encode(new_filename)
        print token

        return jsonify({"errno": 0, "errmsg": "上传成功", "token": token})
    else:
        return jsonify({"errno": 1001, "errmsg": "上传失败"})


if __name__ == '__main__':
    app.run(debug=True)

 附加使用PostMan测试上传文件的操作方法：http://blog.csdn.net/u013420865/article/details/69665180

2 Android端代码实现

代码分三部分：

分别是xml布局文件，Activity类，和Okhttp网络通信类。

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="视频名称："
            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="请输入上传视频名称"
            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="选择视频"
        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="点击上传"
        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>
