# mp-upload-oss-helper
mp-upload-oss-helper 是一个用于辅助微信小程序, 上传文件至 OSS 的后端辅助工具. 虽然 OSS 并未提供小程序的 sdk, 但是提供了通用的 API 接口, 而微信小程序的上传方法, 本质上是一个 POST 请求. 经过查阅 [OSS](https://help.aliyun.com/document_detail/31988.html?spm=a2c4g.11186623.2.2.W0gqKB#reference_smp_nsw_wdb) 和 [微信小程序的文档](https://developers.weixin.qq.com/miniprogram/dev/api/network-file.html), 采用后端计算参数传递给小程序的方式来实现上传
### 后端使用
``` JavaScript
const MpUploadOssHelper = require('mp-upload-oss-helper');
const mpHelper = new MpUploadOssHelper({
accessKeyId: CONFIG.OSS_MP_UPLOAD.AccessKeyId,
accessKeySecret: CONFIG.OSS_MP_UPLOAD.AccessKeySecret,
timeout: 1, // 限制参数的有效时间(单位: 小时)
maxSize: 10 // 限制上传文件大小(单位: Mb)
});
// 生成的参数
const params = mpHelper.createUploadParams();
```
### 小程序使用
```javascript
// 对接后台返回的 oss 参数
const params = {};
wx.uploadFile({
url: OSS_UPLOAD_HOST,
filePath: filePath,
name: 'file',
formData: {
'key': params.key,
'policy': params.policy,
'OSSAccessKeyId': params.OSSAccessKeyId,
'Signature': params.signature,
},
success: function (res) {
resolve(OSS_UPLOAD_HOST + params.key);
},
fail: function (err) {
reject(err);
},
})
```
