Here I am using uni-app as an example to encapsulate a public method of uploading Qiniuyun, which can be copied and used directly at the end to call the method
Just look at the code first, if you have any questions, please leave a message below to discuss
We first create a common folder in the root directory of the project, and then create a qiniuyunUploader.js under common, which can be named at will, this is just my example is not very standardized
qiniuyunUploader.js
(function () {
// 请参考demo的index.js中的initQiniu()方法，若在使用处对options进行了赋值，则此处config不需要赋默认值。init(options) 即updateConfigWithOptions(options)，会对config进行赋值
var config = {
// bucket 所在区域。ECN, SCN, NCN, NA, ASG，分别对应七牛云的：华东，华南，华北，北美，新加坡 5 个区域
qiniuRegion: '',
// 七牛云bucket 外链前缀，外链在下载资源时用到
qiniuBucketURLPrefix: '',
// 获取uptoken方法三选一即可，执行优先级为：uptoken > uptokenURL > uptokenFunc。三选一，剩下两个置空。推荐使用uptokenURL，详情请见 README.md
// 由其他程序生成七牛云uptoken，然后直接写入uptoken
qiniuUploadToken: '',
// 从指定 url 通过 HTTP GET 获取 uptoken，返回的格式必须是 json 且包含 uptoken 字段，例如： {"uptoken": "0MLvWPnyy..."}
qiniuUploadTokenURL: '',
// uptokenFunc 这个属性的值可以是一个用来生成uptoken的函数，详情请见 README.md
qiniuUploadTokenFunction: function () { },
// qiniuShouldUseQiniuFileName 如果是 true，则文件的 key 由 qiniu 服务器分配（全局去重）。如果是 false，则文件的 key 使用微信自动生成的 filename。出于初代sdk用户升级后兼容问题的考虑，默认是 false。
// 微信自动生成的 filename较长，导致fileURL较长。推荐使用{qiniuShouldUseQiniuFileName: true} + "通过fileURL下载文件时，自定义下载名" 的组合方式。
// 自定义上传key 需要两个条件：1. 此处shouldUseQiniuFileName值为false。 2. 通过修改qiniuUploader.upload方法传入的options参数，可以进行自定义key。（请不要直接在sdk中修改options参数，修改方法请见demo的index.js）
// 通过fileURL下载文件时，自定义下载名，请参考：七牛云“对象存储 > 产品手册 > 下载资源 > 下载设置 > 自定义资源下载名”（https://developer.qiniu.com/kodo/manual/1659/download-setting）。本sdk在README.md的"常见问题"板块中，有"通过fileURL下载文件时，自定义下载名"使用样例。
qiniuShouldUseQiniuFileName: false
}
// init(options) 将七牛云相关配置初始化进本sdk
// 在整个程序生命周期中，只需要 init(options); 一次即可
// 如果需要变更七牛云配置，再次调用 init(options); 即可
function init(options) {
updateConfigWithOptions(options);
}
// 更新七牛云配置
function updateConfigWithOptions(options) {
if (options.region) {
config.qiniuRegion = options.region;
} else {
console.error('qiniu uploader need your bucket region');
}
if (options.uptoken) {
config.qiniuUploadToken = options.uptoken;

config.qiniuUploadTokenURL = options.uptokenURL;
} else if (options.uptokenFunc) {
config.qiniuUploadTokenFunction = options.uptokenFunc;
}
if (options.domain) {
config.qiniuBucketURLPrefix = options.domain;
}
config.qiniuShouldUseQiniuFileName = options.shouldUseQiniuFileName
}
// 正式上传的前置方法，做预处理，应用七牛云配置
function upload(filePath, success, fail, options, progress, cancelTask) {
if (null == filePath) {
console.error('qiniu uploader need filePath to upload');
return;
}
if (options) {
updateConfigWithOptions(options);
}
if (config.qiniuUploadToken) {
doUpload(filePath, success, fail, options, progress, cancelTask);

console.error('qiniu UploadTokenFunction result is null, please check the return value');
return
}
doUpload(filePath, success, fail, options, progress, cancelTask);
} else {

console.error('qiniu UploadToken is null, please check the init config or networking');
return
}
var url = uploadURLFromRegionCode(config.qiniuRegion);
var fileName = filePath.split('//')[1];
// 自定义上传key（即自定义上传文件名）。通过修改qiniuUploader.upload方法传入的options参数，可以进行自定义文件名称。如果options非空，则使用options中的key作为fileName
if (options && options.key) {
fileName = options.key;
}
var formData = {
'token': config.qiniuUploadToken
};
// qiniuShouldUseQiniuFileName 如果是 true，则文件的 key 由 qiniu 服务器分配（全局去重）。如果是 false，则文件的 key 使用微信自动生成的 filename。出于初代sdk用户升级后兼容问题的考虑，默认是 false。
if (!config.qiniuShouldUseQiniuFileName) {
formData['key'] = fileName
}
var uploadTask = wx.uploadFile({
url: url,
filePath: filePath,
name: 'file',
formData: formData,
success: function (res) {
var dataString = res.data
// // this if case is a compatibility with wechat server returned a charcode, but was fixed
// if(res.data.hasOwnProperty('type') && res.data.type === 'Buffer'){
// dataString = String.fromCharCode.apply(null, res.data.data)
// }
try {
var dataObject = JSON.parse(dataString);
// 拼接fileURL
var fileURL = config.qiniuBucketURLPrefix + '/' + dataObject.key;
dataObject.fileURL = fileURL;
// imageURL字段和fileURL字段重复，但本sdk不做删除，因为在最初版本使用的是imageURL。直接删除可能导致原有用户升级至新版sdk后出现异常。
dataObject.imageURL = fileURL;
// console.log(dataObject); // 返回数据
if (success) {
success(dataObject);
}
} catch (e) {
// console.log('parse JSON failed, origin String is: ' + dataString)
if (fail) {
fail(e);
}
}
},
fail: function (error) {
console.error(error);
if (fail) {
fail(error);
}
}
})
// 文件上传进度
uploadTask.onProgressUpdate((res) => {
progress && progress(res)
})
// 中断文件上传
cancelTask && cancelTask(() => {
uploadTask.abort()
})
}
// 获取七牛云uptoken, url为后端服务器获取七牛云uptoken接口
function getQiniuToken(callback) {
wx.request({
url: config.qiniuUploadTokenURL,
success: function (res) {
var token = res.data.uptoken;
if (token && token.length > 0) {
config.qiniuUploadToken = token;
if (callback) {
callback();
}
} else {
console.error('qiniuUploader cannot get your token, please check the uptokenURL or server')
}
},
fail: function (error) {
console.error('qiniu UploadToken is null, please check the init config or networking: ' + error);
}
})
}
// 选择七牛云文件上传接口，文件向匹配的接口中传输。ECN, SCN, NCN, NA, ASG，分别对应七牛云的：华东，华南，华北，北美，新加坡 5 个区域
function uploadURLFromRegionCode(code) {
var uploadURL = null;
switch (code) {
case 'ECN': uploadURL = 'https://up.qiniup.com'; break;
case 'NCN': uploadURL = 'https://up-z1.qiniup.com'; break;
case 'SCN': uploadURL = 'https://up-z2.qiniup.com'; break;
case 'NA': uploadURL = 'https://up-na0.qiniup.com'; break;
case 'ASG': uploadURL = 'https://up-as0.qiniup.com'; break;
default: console.error('please make the region is with one of [ECN, SCN, NCN, NA, ASG]');
}
return uploadURL;
}
module.exports = {
init: init,
upload: upload,
}
})();
Finally, we encapsulate a method for us to call, here I create an uploadImage.js under common
uploadImage.js
/**
* 封装上传图片到七牛云
* @param {num} 上传的数量
* @param {status} true： 图片上传，false：视频上传
* @param {callback} 返回方法
* 在main.js 全局引用：import $mUploadImage from '@/common/uploadImage'
* 挂在：Vue.prototype.$mUploadImage = $mUploadImage;
* 调用方法： this.$mUploadImage(1, true, res => {console.log(res)})
*/

module.exports = uploadImagehttps is my encapsulated network request, which can be modified according to my own needs
