看着没什么问题呢

  getPath(points) {
      const { x: x1, y: y1 } = points[0];
      const { x: x2, y: y2 } = points[1];
      const [width, height] = [x2 - x1, y2 - y1];
      return [
        ['M', x1, y1],
        ['L', x1, y1 + height / 2],
        ['L', x2, y1 + height / 2],
        ['L', x2, y2],
      ];
    }

能否实现自动变化路径呢，以适配各种方向的节点，搞不明白这

G6 中 Path 遵守 SVG Path 规范，不过使用的是数组形式表达。 自动寻径能力仅 5.x 版本可用 Demo
