钉钉小程序上传文件到七牛云或阿里云(OSS)实现

共有代码

function getTimestamp() {
  return new Date().getTime() / 1000;
}

dd.chooseImage({
      sourceType: ['camera', 'album'],
      count: 3,
      success: (res) => {
        (res.filePaths || res.apFilePaths || []).forEach(path => {
          uploadFile(path);
        });
      },
      fail: (res) => {
        if (res.error != 11) {
          dd.showToast({content: 'fail'});
        }
      }
}); 

• 1、上传到阿里云

 function uploadFile(path) {
      if (!path) return;
      const hashCode = hash
        .sha1()
        .update(`${getTimestamp() + Math.random()}`)
        .digest('hex');
      const fileName = `${hashCode}${/\.[^\.]+$/.exec(filePath)[0]}`;
      const name = filePath.match(/\/([^/]*)$/)[1];
      const key = `attachments/${moment().format('YYYYMMDD')}/${fileName}`;
      const { fileToken: { accessKeyId, policy, securityToken, signature, expire } } = app.globalData;
      const formData = {
        name, key, policy,
        OSSAccessKeyId: accessKeyId,
        Signature: signature,
        'x-oss-security-token': securityToken,
        success_action_status: '200',
      };

      dd.uploadFile({
        url: config.fileHost, // 替换自己的阿里云地址
        fileType: 'image',
        fileName: 'file',
        filePath: filePath,
        formData: formData,
        success: (res) => {
          console.log(res, { key: formData.key, name: name });
        },
        fail: (err) => {
          dd.showToast({ content: '上传失败，稍后再试！' });
        },
        complete: (res) => {
          dd.hideLoading();
        }
      });
}
