公司為了節(jié)省流量費(fèi)讓前端直接上傳上傳七牛云服務(wù)起上球恤，本人也是試了三種方法哀九，踩了無(wú)數(shù)次坑剿配，通過(guò)一天的努力，最終上傳成功了阅束。再次記錄一下惨篱。
環(huán)境：uniapp + uView2.0
代碼如下：
vue上傳頁(yè)面：

<!-- 上傳圖片 -->
<view style="transform: translateX(-10rpx);">
      <u-upload
          :fileList="fileList"
          @afterRead="afterRead"
          @delete="deletePic"
          name="1"
          multiple
          :previewFullImage="true"
          :maxCount="9"
      ></u-upload>
    <u-line length="690rpx" color="#F6F6F6" margin="30rpx 0 33rpx 0"></u-line>
</view>
<script>
export default {
    data() {
        return {
          fileList: [],
          fileUrlList: [],
        };
    },
    methods: {
        // 刪除圖片
        deletePic(event) {
          this.fileList.splice(event.index, 1)
          this.fileUrlList.splice(event.index, 1)
        },
     // 新增圖片
    async afterRead(event) {
      // 當(dāng)設(shè)置 multiple 為 true 時(shí), file 為數(shù)組格式，否則為對(duì)象格式
      let lists = [].concat(event.file)
      let fileListLen = this.fileList.length
      lists.map((item) => {
        this.fileList.push({
          ...item,
          status: 'uploading',
          message: '上傳中'
        })
      })
      for (let i = 0; i < lists.length; i++) {
        const result = this.$uploader.upload2qiniu(lists[i].url)
        result.then(res=>{
          this.fileUrlList.push(res.msg)
        })
        let item = this.fileList[fileListLen]
        this.fileList.splice(fileListLen, 1, Object.assign(item, {
          status: 'success',
          message: '',
          url: result
        }))
        fileListLen++
      }
    },
    chooseLocation() {
      let that = this;
      uni.chooseLocation({
        success: function(res) {
          that.form.address = res.name;
          that.form.latitude = res.latitude;
          that.form.longitude = res.longitude;
        },
        fail(err) {
          console.log(err)
        }
      });
    },
    }
};
</script>

主要的js文件

1.獲取上傳所用token需要后端人員提供接口 2.上傳完成需要后端提供圖片群路徑的接口

const dateFormat = require('dateformat');
var randomString = require('random-string');

class Uploader {
    constructor() {
        this.qiniuTokenApi = '獲取token的后端地址';
    }
    //七牛云上傳
    async upload2qiniu(file) {
        // 獲取token
        let tokenData = await this.getToken();
        let token = tokenData.msg
        return new Promise((resolve, reject) => {
        let customFileName = config.qiNiuSpaceName + "/" + dateFormat(new Date(), "yyyy/mm/dd/HH") + "/" + randomString({
            length: 10
        })
            uni.uploadFile({
                url: config.uploadQiNiuDomain,
                filePath: file,
                name: 'file',
                formData: {
                    'key': customFileName, // 存到七牛云后的文件名字围俘，訪問(wèn)圖片會(huì)用到
                    'token': token, // uploadToken砸讳，需要?jiǎng)討B(tài)獲取，調(diào)用云函數(shù)接口獲取
                },
                // 存成功后的回調(diào)
                success: async (uploadFileRes) => {
                    let key = JSON.parse(uploadFileRes.data).key;
                    // 空間綁定的域名（在七牛云配置）+key就是文件的訪問(wèn)地址
                    let url = await this.getUrl(JSON.parse(uploadFileRes.data).key);
                    resolve(url)
                },
                fail: (err) => {

                }
            });
        })
    }
    async getToken() {
        return new Promise((resolve, reject) => {
            uni.request({

                method: "GET",
                success(res) {
                    resolve(res.data)
                },
                fail(err) {
                    reject(err)
                }
            })
        })
    }

    async getUrl(key) {
        let url = '上傳圖片之后獲取全路徑的url ' + '?key=' + key
        return new Promise((resolve, reject) => {
            uni.request({
                url: url,
                method: "GET",
                success(res) {
                    resolve(res.data)
                },
                fail(err) {
                    reject(err)
                }
            })
        })
    }
}
export default new Uploader();

使用的依賴庫(kù)有："dateformat": "^3.0.3", "random-string": "^0.2.0",
