Java实现腾讯云视频上传的功能

1.上传视频的页面

<!DOCTYPE html>

<head>

<title>Gary_Video</title>

</head>

<body>

<h1>Gary上传视频</h1>

</from>

<a id="uploadVideoNow" href="javascript:void(0);" onclick="change()">点击上传视频</a>

var getSignature = function(callback)

{

$.ajax({

url:"/api/tengxun/sign",

type:"POST",

success:function(result)

{

alert(result);

//即可上传视频

callback(result);

}

})

}

function change()

{

$("#uploadVideoNow-file").click();

}

function changeInput(e){

//alert(e.files[0].name);

var videoFile = e.files[0];

qcVideo.ugcUploader.start({

//视频文件

videoFile:videoFile,

//上传位置

getSignature:getSignature,

//是否上传声音

allowAudio:1,

//上传成功

success:function(result)

{

alert("success");

//上传失败

error:function(result)

{

alert("error");

//上传过程中

progress:function(result)

{

//上传完成

finish:function(result)

{

alert("finish");

}

})

}

</script>

</body>

</html>

video.html

2.构建类

package com.hrhq.core.api.controller;

import sun.misc.BASE64Encoder;

import javax.crypto.Mac;

import javax.crypto.spec.SecretKeySpec;

import java.net.URLEncoder;

public class Signature {

private String secretId;

private String secretKey;

private long currentTime;

private int random;

private int signValidDuration;

private static final String HMAC_ALGORITHM = "HmacSHA1";

private static final String CONTENT_CHARSET = "UTF-8";

public static byte[] byteMerger(byte[] byte1, byte[] byte2) {

byte[] byte3 = new byte[byte1.length + byte2.length];

System.arraycopy(byte1, 0, byte3, 0, byte1.length);

System.arraycopy(byte2, 0, byte3, byte1.length, byte2.length);

return byte3;

}

public String getUploadSignature()

throws Exception {

String strSign = "";

String contextStr = "";

long endTime = this.currentTime + this.signValidDuration;

contextStr = contextStr + "secretId=" + URLEncoder.encode(this.secretId, "utf8");

contextStr = contextStr + "&currentTimeStamp=" + this.currentTime;

contextStr = contextStr + "&expireTime=" + endTime;

contextStr = contextStr + "&random=" + this.random;

contextStr = contextStr + "&procedure=QCVB_SimpleProcessFile(1,1)";

try {

Mac mac = Mac.getInstance("HmacSHA1");

SecretKeySpec secretKey = new SecretKeySpec(this.secretKey.getBytes("UTF-8"), mac.getAlgorithm());

mac.init(secretKey);

byte[] hash = mac.doFinal(contextStr.getBytes("UTF-8"));

byte[] sigBuf = byteMerger(hash, contextStr.getBytes("utf8"));

strSign = new String(new BASE64Encoder().encode(sigBuf).getBytes());

strSign = strSign.replace(" ", "").replace("\n", "").replace("\r", "");

} catch (Exception e) {

throw e;

}

return strSign;

}

public void setSecretId(String secretId) {

this.secretId = secretId;

}

public void setSecretKey(String secretKey) {

this.secretKey = secretKey;

}

public void setCurrentTime(long currentTime) {

this.currentTime = currentTime;

}

public void setRandom(int random) {

this.random = random;

}

public void setSignValidDuration(int signValidDuration) {

this.signValidDuration = signValidDuration;

}

3.方法腾讯云API

Signature.java得到加密后的字符串

　　通过IndexController.java中的getSign()方法将appkey和appid进行加密，得到加密后的字符串并通过函数指针回传给getSignature:getSignature

package com.hrhq.core.api.controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import org.springframework.web.bind.annotation.RestController;

import org.springframework.web.servlet.ModelAndView;

import java.util.Random;

@RestController

@RequestMapping("/api/tengxun")

public class IndexController {

@RequestMapping("/")

public ModelAndView index(){

return new ModelAndView("/video.html");

}

@RequestMapping("/sign")

@ResponseBody

public String getSign()

{

//得到Sign

Signature sign = new Signature();

//个人API密钥中的Secret Id

sign.setSecretId("AKIDZw4wZwpFBsNcb5rM8fxzlHdjZ9TZ25Wn");

//个人API密钥中的Secret Key

sign.setSecretKey("A4j8HAoCPN6brsc7MNDn8D2f3B8qJYXK");

sign.setCurrentTime(System.currentTimeMillis() / 1000);

sign.setRandom(new Random().nextInt(java.lang.Integer.MAX_VALUE));

sign.setSignValidDuration(3600 * 24 * 2);

String signature = null;

try {

signature = sign.getUploadSignature();

System.out.println("signature : " + signature);

} catch (Exception e) {

System.out.print("获取签名失败");

e.printStackTrace();

}

return signature;

}
