Promise.all并行请求案例

    if (dealFileList.value && topicFileList.value && accountFileList.value) {
        state.btnLoading = true;
        const [res01, res02, res03] = await Promise.all([
            handleImportFile(dealFileList.value, '/economic/economyDeal/import'),
            handleImportFile(topicFileList.value, '/economic/economyMain/import'),
            handleImportFile(accountFileList.value, '/economic/economyAccount/import'),
        ]).catch((error) => {
            console.log('output-> error::: ', error)
        })
        if (res01 && res02 && res03) {
            state.btnLoading = false;
            onCancelClick();
            resetFile();
            message.success('文件上传成功')
        }
    }

案例

      const initDictOpts = () => {
          const req01 = getDicByType({typeCode: 'assignLevel'});
          const req02 = getDicByType({typeCode: 'verificationResponsibleUnit'});
          const req03 = getDicByType({typeCode: 'involvedUnit'});
          const req04 = getDicByType({typeCode: 'accountableSituation'});
          // 使用Promise.all同时执行多个请求
          Promise.all([req01, req02, req03, req04])
            .then((responses: any) => {
                // 所有请求都成功完成
                console.log('output-> response::: 【initDictOpts】', responses)
                dictObj.assignLevelOpts = responses[0].data;
                dictObj.verificationResponsibleUnitOpts = responses[1].data;
                dictObj.involvedUnitOpts = responses[2].data;
                dictObj.accountableSituationOpts = responses[3].data;
            })
            .catch(error => {
                // 请求中的任何一个失败都会触发catch
                console.error(error);
            });
      }
