Otherwise, multiple repeated pop-ups will be opened when multiple requests are triggered in succession. if (! Window. hasPoped402Modal) {// Popup window modal.warning ({title: 'prompt ', content: '<p> Your account logs in to another device. If it is not done by yourself, please change the login password in time. </p>', onOk: () => {toLogin() // Click ok to jump to the login page.

Window.haspoped402modal = false}}) // Global flag, Open the window.haspoped402Modal = true}} return promise.resolve (response.data)} else {return Promise.reject(response) } } ) export default myRequestCopy the code
