阿里云OSS API上传文档：[基于OSS API上传 (aliyun.com)](https://help.aliyun.com/document_detail/412896.html?spm=5176.8465980.help.dexternal.462e14501v1OeZ&scm=20140722.S_help%40%40%E6%96%87%E6%A1%A3%40%40412896.S_hot%2Bos0.ID_412896-RL_oss%20%20api-LOC_consoleUNDhelp-OR_ser-V_2-P0_0)

### 服务端加密方案：
1、前端上传文件 --> 服务端将文件上传至OSS；
2、后端存储OSS返回的文件地址；
3、当前端访问数据时，返回一条限时可访问的链接；
接口：/s/file/oss/upload-public-multipart-file
示例：
```bash
curl -X POST "https://dev-s-gateway-kip.kerryonvip.com/api/file/v1/s/file/oss/upload-public-multipart-file" -H "accept: */*" -H "Content-Type: multipart/form-data" -F "file=@juejin二维码.png;type=image/png"
```
Response body
```json
{
  "url": "https://kip-public-dev.oss-cn-shanghai.aliyuncs.com/dd032c36294344eda0d7d3476cfee6f7_juejin二维码.png"
}
```
Response headers
```
 cache-control: no-cache, no-store, max-age=0, must-revalidate connection: keep-alive  content-type: application/json  date: Wed, 07 Dec 2022 03:38:45 GMT  expires: 0  pragma: no-cache  referrer-policy: no-referrer  strict-transport-security: max-age=15724800; includeSubDomains  transfer-encoding: chunked  x-content-type-options: nosniff  x-frame-options: DENY  x-request-id: c0fef2fd74e5c153962bb543b3399102 x-xss-protection: 1 ; mode=block
```

### 前端加密：

上传：
1、在前端先将文件转为base64数据；
2、将base64数据通过AES1加密；
3、最后将文件以 txt文本方式上传至OSS
4、保存OSS文件

下载：
当用户返回访问条件时，下载txt文件，先解密，然后再将base64渲染至前端页面；




# 微信小程序上传图片

上传图片的话就做上传头像的时候遇到了，就拿上传头像举个例子吧

得知道我们都用到什么api，而且提醒一下，这个需要后端配合，因为最后需要上传到服务器

先写一下wxml吧

```csharp
<view class='box' bindtap='uploadHeadImg'>上传</view>
```

-   其一，我们得先提示菜单：[从相册中选择，拍照]----`wx.showActionSheet`

```jsx
uploadHeadImg: function() {
        let a = this;
        wx.showActionSheet({
            itemList: [ "从相册中选择", "拍照" ],
            itemColor: "#f7982a",
            success: function(e) {
            //album:相册   //camera拍照
                e.cancel || (0 == e.tapIndex ? a.chooseWxImageShop("album") : 1 == e.tapIndex && a.chooseWxImageShop("camera"));
            }
        });
    },
```

-   其二，选择照片或者拍照，返回临时路径----`wx.chooseImage`

```jsx
//a：选择的类型  //album:相册   //camera拍照
chooseWxImageShop: function(a) {
        var e = this;
        wx.chooseImage({
            sizeType: [ "original", "compressed" ],
            sourceType: [ a ],//类型
            count:1,
            success: function(a) {
                if(a.tempFiles[0].size> 2097152){
                    wx.showModal({
                        title: "提示",
                        content: "选择的图片过大，请上传不超过2M的图片",
                        showCancel: !1,
                        success: function(a) {
                            a.confirm;
                        }
                    })
                }else{
                    //把图片上传到服务器
                    e.upload_file(a.tempFilePaths[0])
                }
            }
        });
    },
```

-   其三，把图片上传到服务器----`wx.uploadFile`

```jsx
upload_file: function(e) {
    wx.showLoading({
        title: "上传中"
    });
    wx.uploadFile({
        url:url,
        filePath: e,//图片路径
        name: "user_avatar",
        formData: {
            token: a.globalData.token,
            user_avatar: "filePath"
        },
        header: {
            "Content-Type": "multipart/form-data"
        },
        success: function(a) {
            wx.hideLoading();
            wx.showToast({
                title: "上传成功",
                icon: "success",
                duration: 3000
            });
        },
        fail: function(a) {
            wx.hideLoading();
            wx.showToast({
                title: "上传失败",
                icon: "none",
                duration: 3000
            });
        }
    });
},
```

### 上传成功
