这篇文章给大家介绍怎么在Android中使用OKHttp库将视频文件上传到服务器，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
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:\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)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" android:layout_width="match_parent" android:layout_height="wrap_content" android:max="100" /> </LinearLayout>
