Promise 的使用，调用当前组件的this的时候的使用方法

const params = {operType:'3',//发布人改派reason:sendDesc,sendStaff:this.state.selectChangeMan,workId:workId,attachFiles:attachFiles,
};
// console.log('最终提交的信息====',params);
let component = this;//在promise中，this的含义已经改变，所以需要通过别名的方法将this引进来
Modal.confirm({title: '确定将此工单改派给 '+ this.state.selectChangeMan + ' 吗？',icon: <ExclamationCircleOutlined />,onOk() {let prom =  new Promise((resolve, reject) => {submitSendPublish(params).then((resinfo)=> {//异步加载数据。发布人改派// console.log('改派返回的信息',resinfo);try{if(resinfo.code==="00"){message.success('改派成功');resolve('success');//为then返回成功的参数，返回的值是success}else{reject('fail');//为then返回失败的参数，返回的值是failmessage.error('改派失败，',resinfo.msg);}}catch (e) {reject('error');console.log('改派失败===',e);message.error('改派失败');}});}).catch((error) => console.log('Promise errors!'+ error));prom.then((res) => {if(res === 'success'){component.close(false);history.back();//改派}else if(res === 'fail'){console.log('失败',res);}});return prom;//控件必须返回Promise对象。},onCancel() {},
});
