前端如何获取http状态码400的返回值

axios.get("/check_mobile_and_sent_code",{withCredentials:true,params:{mobile:formInline.mobile}}).then(res=>{
                        console.log(res);
                        //if(res.result==true){
                            if (!this.timer) {
                                this.count = this.TIME_COUNT;
                                this.show = false;
                                this.timer = setInterval(() => {
                                    if (this.count > 0 && this.count <= this.TIME_COUNT) {
                                        this.count--;
                                    } else {
                                        this.show = true;
                                        clearInterval(this.timer);
                                        this.timer = null;
                                    }
                                }, 1000)
                            }
                        //}
                    }).catch(error=>{
                        console.log(error.response.data);
                        console.log(error.response.status);
                        console.log(error.response.headers); 
                        console.log('Error', error.message);
                        console.log(error.config);
                    })
