最近疫情严重，公司准备出一个在线视频会议功能，需要调用腾讯会议的API，经过查看腾讯的api文档和与腾讯技术人员交流，终于能成功调用Api接口了！
腾讯会议官方API：https://cloud.tencent.com/document/product/1095/42407
首先第一步需要申请腾讯 API 接入
申请好了以后，会邮件发给你APPID，SecretId，SecretKey三个参数。
我们以创建会议为例，步骤如下：
一、生成body参数
//body参数
String req_body="{\n" +
"\t\"userid\": \"tester\",\n" +
"\t\"instanceid\": 1,\n" +
"\t\"subject\": \"tester's meeting\",\n" +
"\t\"type\": 0,\n" +
"\t\"hosts\": [{\n" +
"\t\t\"userid\": \"tester\"\n" +
"\t}],\n" +
"\t\"start_time\": \""+createTime+"\",\n" +
"\t\"end_time\": \""+createtomorrow+" \",\n" +
"\t\"settings \": {\n" +
"\t\t\"mute_enable_join \": true,\n" +
"\t\t\"allow_unmute_self \": false,\n" +
"\t\t\"mute_all \": false,\n" +
"\t\t\"host_video \": true,\n" +
"\t\t\"participant_video \": false,\n" +
"\t\t\"enable_record \": false,\n" +
"\t\t\"play_ivr_on_leave\": false,\n" +
"\t\t\"play_ivr_on_join\": false,\n" +
"\t\t\"live_url\": false\n" +
"\t}\n" +
"}";二、生成签名
String num="";//随机数
String signature = sign(SecretId, SecretKey, "POST", num, createTime, uri, req_body);
三、请求
String code=doPost(url,Content_Type,SecretId,createTime,num,appId,signature,datas);完整代码如下：
package com.jbox.common.utils;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
