Edge API
2.2 Edge
顶点 id 格式的修改也影响到了边的 Id 以及源顶点和目标顶点 id 的格式。
EdgeId是由 src-vertex-id + direction + label + sort-values + tgt-vertex-id 拼接而成，
-但是这里的顶点id类型不是通过引号区分的，而是根据前缀区分：
- 当 id 类型为 number 时，EdgeId 的顶点 id 前有一个前缀
L，形如 “L123456>1»L987654” - 当 id 类型为 string 时，EdgeId 的顶点 id 前有一个前缀
S，形如 “S1:peter>1»S2:lop”
接下来的示例均假设已经创建好了前述的各种schema和vertex信息

-2.2.6 获取符合条件的边
Params
- vertex_id: 顶点id
- direction: 边的方向(OUT | IN | BOTH)
- label: 边的标签
- properties: 属性键值对(根据属性查询的前提是预先建立了索引)
- offset：偏移，默认为0
- limit: 查询数目，默认为100
- page: 页号
支持的查询有以下几种：
- 提供vertex_id参数时，不可以使用参数page，direction、label、properties可选，offset和limit可以 -限制结果范围
- 不提供vertex_id参数时，label和properties可选
- 如果使用page参数，则：offset参数不可用（不填或者为0），direction不可用，properties最多只能有一个
- 如果不使用page参数，则：offset和limit可以用来限制结果范围，direction参数忽略
属性键值对由JSON格式的属性名称和属性值组成，允许多个属性键值对作为查询条件，属性值支持精确匹配和范围匹配，精确匹配时形如properties={"weight":0.8}，范围匹配时形如properties={"age":"P.gt(0.8)"},范围匹配支持的表达式如下：
| 表达式 | 说明 |
|---|---|
| P.eq(number) | 属性值等于number的边 |
| P.neq(number) | 属性值不等于number的边 |
| P.lt(number) | 属性值小于number的边 |
| P.lte(number) | 属性值小于等于number的边 |
| P.gt(number) | 属性值大于number的边 |
| P.gte(number) | 属性值大于等于number的边 |
| P.between(number1,number2) | 属性值大于等于number1且小于number2的边 |
| P.inside(number1,number2) | 属性值大于number1且小于number2的边 |
| P.outside(number1,number2) | 属性值小于number1且大于number2的边 |
| P.within(value1,value2,value3,…) | 属性值等于任何一个给定value的边 |

- label: 边的标签
- properties: 属性键值对 (根据属性查询的前提是预先建立了索引)
- keep_start_p: 默认为 false，当设置为 true 后，不会自动转义范围匹配输入的表达式，例如此时
properties={"age":"P.gt(0.8)"}会被理解为精确匹配，即 age 属性等于 “P.gt(0.8)” - offset：偏移，默认为 0

-此时"page": null表示已经没有下一页了 (注: 后端为 Cassandra 时，为了性能考虑，返回页恰好为最后一页时，返回 page 值可能非空，通过该 page 再请求下一页数据时则返回 空数据 及 page = null，其他情况类似)

-根据Label+Id删除边
通过指定Label参数和Id来删除边时，一般来说其性能比仅根据Id删除会更好。
