创建了一个叫图片上传的按钮，选中时需要查看选中的图片

     <GridItem xs={6}>
        <FormControl className={classes.formControl}>
          <input
            accept="image/*"
            className={classes.input}
            style={{ display: 'none' }}
            id="raised-button-file"
            multiple
            type="file"
          />
          <label htmlFor="raised-button-file">
            <Button
              variant="raised"
              component="span"
              className={classes.button}
            >
              Upload Image
            </Button>
          </label>
        </FormControl>
      </GridItem>
