uniapp----upload pictures and videos to Tencent Cloud COS
1. Go to the official website to download cos-wx-sdk-v5.min.js, and quote it. Full code:
import func from '@/config/func.js';
import {
myRequest
} from '@/config/api.js';
var COS = require('./cos-wx-sdk-v5.min');
const config = {
Bucket: 'XXXXXXXXX', // 存储桶的名称，命名规则为 BucketName-APPID，此处填写的存储桶名称必须为此
Region: 'xxxxx', // 存储桶所在地域
https: 'https://'
};
var cos = new COS({
// ForcePathStyle: true, // 如果使用了很多存储桶，可以通过打开后缀式，减少配置白名单域名数量，请求时会用地域域名
SimpleUploadMethod: 'putObject', // 强烈建议，高级上传、批量上传内部对小文件做简单上传时使用putObject,sdk版本至少需要v1.3.0
getAuthorization: function(options, callback) {
// 初始化时不会调用，只有调用 cos 方法（例如 cos.putObject）时才会进入
// 异步获取临时密钥
myRequest('getTencentUploadToken', 'POST', {
bucket: config.Bucket,
region: config.Region,
}).then(result => {
let data = result.data;
let credentials = data && data.credentials;
if (!data || !credentials) return console.error('credentials invalid');
callback({
TmpSecretId: credentials.tmpSecretId,
TmpSecretKey: credentials.tmpSecretKey,
// v1.2.0之前版本的 SDK 使用 XCosSecurityToken 而不是 SecurityToken
SecurityToken: credentials.sessionToken,
// 建议返回服务器时间作为签名的开始时间，避免用户浏览器本地时间偏差过大导致签名错误
StartTime: data.startTime, // 时间戳，单位秒，如：1580000000
ExpiredTime: data.expiredTime, // 时间戳，单位秒，如：1580000900
});
})
}
});
// 选择图片
const uniChooseImage = () => {
return new Promise((resolve, rejct) => {
uni.chooseImage({
// 从本地相册选择图片或使用相机拍照。
count: 1, //默认选择1张图片
sizeType: ['original', 'compressed'], //original 原图，compressed 压缩图，默认二者都有
success: res1 => {
resolve(res1.tempFilePaths[0]);
}
});
});
}
// 上传视频封面图片 腾讯云
const cosUpLoadimg = async () => {
let file = '';
let promise;
// 获取临时路径
await uniChooseImage().then(res => {
file = res
})
await myRequest('getTencentUploadFilename', 'POST', {
file_name: file
}).then(v => {
let keyz = v.data; //获取腾讯cos上传文件名
promise = new Promise((resolve, rejct) => {
func.loading("上传中...")
// 微信小程序里获取文件管理器
var wxfs = uni.getFileSystemManager();
wxfs.readFile({
filePath: file,
success: function(res) {
cos.putObject({
Bucket: config.Bucket,
Region: config.Region,
Key: keyz,
Body: res.data, // Body里传入的是文件内容
}, (err, data) => {
if (data.statusCode == 200) {
let datas = {
coverImgAll: config.https + data
.Location,
coverImg: keyz
}
resolve(datas);
} else {
func.alert('请重新上传！');
}
uni.hideLoading();
});
},
fail: function(err) {
uni.hideLoading();
rejct(err)
console.error(err)
},
});
});
})
return promise;
};
// 选择视频
const uniChoosevideo = () => {
return new Promise((resolve, rejct) => {
uni.chooseVideo({
sourceType: ['album'],
success: function(res) {
resolve(res.tempFilePath);
// self.src = res.tempFilePath;
}
});
});
}
// 上传视频 到腾讯云
const cosChoosevideo = async () => {
let uploadFile = '';
let promise;
await uniChoosevideo().then(res => {
uploadFile = res
})
await myRequest('getTencentUploadFilename', 'POST', {
file_name: uploadFile
}).then(v => {
let keyz = v.data;//获取腾讯cos上传文件名
promise = new Promise((resolve, rejct) => {
func.loading("上传中...");
var wxfs = uni.getFileSystemManager();
wxfs.readFile({
filePath: uploadFile,
success: function(res) {
cos.putObject({
Bucket: config.Bucket,
Region: config.Region,
Key: keyz, //临时路径 后台截取获取
Body: res.data, // Body里传入的是文件内容
}, (err, data) => {
if (data.statusCode == 200) {
let datas = {
videoUrl: config.https + data.Location,
video_link: keyz
}
resolve(datas);
console.log('www', datas);
}else {
func.alert('请重新上传！');
}
uni.hideLoading();
});
},
fail: function(err) {
uni.hideLoading();
rejct(err)
console.error(err)
},
});
});
})
return promise;
}
module.exports = {
cosChoosevideo,
cosUpLoadimg
}
2. Call it in the page you need
import upFile from '@/config/upFile.js';
// 上传视频或者封面
upFileBtn(tag) {
if (tag == 1) {
//视频 腾讯云
upFile.cosChoosevideo().then(v => {
this.videoUrl = v.videoUrl;
this.video_link = v.video_link;
})
}
if (tag == 2) {
//上传图片 腾讯云
upFile.cosUpLoadimg().then(v => {
this.coverImg = v.coverImg;
this.coverImgAll = v.coverImgAll;
})
}
},
