相关代码块儿如下： ``` this.$http.post('/api/XXX', this.XXX, { progress: progressEvent => { if (progressEvent.lengthComputable) { this.$nextTick(() => { // this.percent = Math.ceil((progressEvent.loaded / progressEvent.total) * 100); console.log(Math.ceil((progressEvent.loaded / progressEvent.total) * 100)); }) }...
