| HugeGraph支持的Traverser API包括： |
| K-out API，根据起始顶点，查找恰好N步可达的邻居，分为基础版和高级版： 基础版使用GET方法，根据起始顶点，查找恰好N步可达的邻居 高级版使用POST方法，根据起始顶点，查找恰好N步可达的邻居，与基础版的不同在于： 支持只统计邻居数量 支持边属性过滤 支持返回到达邻居的最短路径 K-neighbor API，根据起始顶点，查找N步以内可达的所有邻居，分为基础版和高级版： 基础版使用GET方法，根据起始顶点，查找N步以内可达的所有邻居 高级版使用POST方法，根据起始顶点，查找N步以内可达的所有邻居，与基础版的不同在于： 支持只统计邻居数量 支持边属性过滤 支持返回到达邻居的最短路径 Same Neighbors, 查询两个顶点的共同邻居 Jaccard Similarity API，计算jaccard相似度，包括两种： 一种是使用GET方法，计算两个顶点的邻居的相似度（交并比） 一种是使用POST方法，在全图中查找与起点的jaccard similarity最高的N个点 Shortest Path API，查找两个顶点之间的最短路径 All Shortest Paths，查找两个顶点间的全部最短路径 Weighted Shortest Path，查找起点到目标点的带权最短路径 Single Source Shortest Path，查找一个点到其他各个点的加权最短路径 Multi Node Shortest Path，查找指定顶点集之间两两最短路径 Paths API，查找两个顶点间的全部路径，分为基础版和高级版： 基础版使用GET方法，根据起点和终点，查找两个顶点间的全部路径 高级版使用POST方法，根据一组起点和一组终点，查找两个集合间符合条件的全部路径 Customized Paths API，从一批顶点出发，按（一种）模式遍历经过的全部路径 Template Path API，指定起点和终点以及起点和终点间路径信息，查找符合的路径 Crosspoints API，查找两个顶点的交点（共同祖先或者共同子孙） Customized Crosspoints API，从一批顶点出发，按多种模式遍历，最后一步到达的顶点的交点 Rings API，从起始顶点出发，可到达的环路路径 Rays API，从起始顶点出发，可到达边界的路径（即无环路径） Fusiform Similarity API，查找一个顶点的梭形相似点 Vertices API 按ID批量查询顶点； 获取顶点的分区； 按分区查询顶点； Edges API 按ID批量查询边； 获取边的分区； 按分区查询边； 3." /> |

| <h3 id="31-traverser-api概述">3.1 traverser API概述</h3> |
| <p>HugeGraphServer为HugeGraph图数据库提供了RESTful API接口。除了顶点和边的CRUD基本操作以外，还提供了一些遍历（traverser）方法，我们称为<code>traverser API</code>。这些遍历方法实现了一些复杂的图算法，方便用户对图进行分析和挖掘。</p> |
| <p>HugeGraph支持的Traverser API包括：</p> |
| <ul> |
| <li>K-out API，根据起始顶点，查找恰好N步可达的邻居，分为基础版和高级版： |
| <ul> |
| <li>基础版使用GET方法，根据起始顶点，查找恰好N步可达的邻居</li> |
| <li>高级版使用POST方法，根据起始顶点，查找恰好N步可达的邻居，与基础版的不同在于： |
| <ul> |
| <li>支持只统计邻居数量</li> |
| <li>支持边属性过滤</li> |
| <li>支持返回到达邻居的最短路径</li> |
| </ul> |
| </li> |
| </ul> |
| </li> |
| <li>K-neighbor API，根据起始顶点，查找N步以内可达的所有邻居，分为基础版和高级版： |
| <ul> |
| <li>基础版使用GET方法，根据起始顶点，查找N步以内可达的所有邻居</li> |
| <li>高级版使用POST方法，根据起始顶点，查找N步以内可达的所有邻居，与基础版的不同在于： |
| <ul> |
| <li>支持只统计邻居数量</li> |
| <li>支持边属性过滤</li> |
| <li>支持返回到达邻居的最短路径</li> |
| </ul> |
| </li> |
| </ul> |
| </li> |
| <li>Same Neighbors, 查询两个顶点的共同邻居</li> |
| <li>Jaccard Similarity API，计算jaccard相似度，包括两种： |
| <ul> |
| <li>一种是使用GET方法，计算两个顶点的邻居的相似度（交并比）</li> |
| <li>一种是使用POST方法，在全图中查找与起点的jaccard similarity最高的N个点</li> |
| </ul> |
| </li> |
| <li>Shortest Path API，查找两个顶点之间的最短路径</li> |
| <li>All Shortest Paths，查找两个顶点间的全部最短路径</li> |
| <li>Weighted Shortest Path，查找起点到目标点的带权最短路径</li> |
| <li>Single Source Shortest Path，查找一个点到其他各个点的加权最短路径</li> |
| <li>Multi Node Shortest Path，查找指定顶点集之间两两最短路径</li> |
| <li>Paths API，查找两个顶点间的全部路径，分为基础版和高级版： |
| <ul> |
| <li>基础版使用GET方法，根据起点和终点，查找两个顶点间的全部路径</li> |
| <li>高级版使用POST方法，根据一组起点和一组终点，查找两个集合间符合条件的全部路径</li> |
| </ul> |
| </li> |
| <li>Customized Paths API，从一批顶点出发，按（一种）模式遍历经过的全部路径</li> |
| <li>Template Path API，指定起点和终点以及起点和终点间路径信息，查找符合的路径</li> |
| <li>Crosspoints API，查找两个顶点的交点（共同祖先或者共同子孙）</li> |
| <li>Customized Crosspoints API，从一批顶点出发，按多种模式遍历，最后一步到达的顶点的交点</li> |
| <li>Rings API，从起始顶点出发，可到达的环路路径</li> |
| <li>Rays API，从起始顶点出发，可到达边界的路径（即无环路径）</li> |
| <li>Fusiform Similarity API，查找一个顶点的梭形相似点</li> |
| <li>Vertices API |
| <ul> |
| <li>按ID批量查询顶点；</li> |
| <li>获取顶点的分区；</li> |
| <li>按分区查询顶点；</li> |
| </ul> |
| </li> |
| <li>Edges API |
| <ul> |
| <li>按ID批量查询边；</li> |
| <li>获取边的分区；</li> |
| <li>按分区查询边；</li> |
| </ul> |
| </li> |
| </ul> |

| <li>skip_degree：用于设置查询过程中舍弃超级顶点的最小边数，即当某个顶点的邻接边数目大于 skip_degree 时，完全舍弃该顶点。选填项，如果开启时，需满足 <code>skip_degree >= max_degree</code> 约束，默认为0 (不启用)，表示不跳过任何点 (注意: 开启此配置后，遍历时会尝试访问一个顶点的 skip_degree 条边，而不仅仅是 max_degree 条边，这样有额外的遍历开销，对查询性能影响可能有较大影响，请确认理解后再开启)</li> |
| </ul> |
| </li> |
| <li>max_depth：步数，必填项</li> |
| <li>nearest：nearest为true时，代表起始顶点到达结果顶点的最短路径长度为depth，不存在更短的路径；nearest为false时，代表起始顶点到结果顶点有一条长度为depth的路径（未必最短且可以有环），选填项，默认为true</li> |
| <li>count_only：Boolean值，true表示只统计结果的数目，不返回具体结果；false表示返回具体的结果，默认为false</li> |
| <li>with_path：true表示返回起始点到每个邻居的最短路径，false表示不返回起始点到每个邻居的最短路径，选填项，默认为false</li> |
| <li>with_vertex，选填项，默认为false： |
| <ul> |
| <li>true表示返回结果包含完整的顶点信息（路径中的全部顶点） |
| <ul> |
| <li>with_path为true时，返回所有路径中的顶点的完整信息</li> |
| <li>with_path为false时，返回所有邻居的完整信息</li> |
| </ul> |
| </li> |
| <li>false时表示只返回顶点id</li> |
| </ul> |
| </li> |
| <li>capacity：遍历过程中最大的访问的顶点数目，选填项，默认为10000000</li> |
| <li>limit：返回的顶点的最大数目，选填项，默认为10000000</li> |

| <h5 id="3241-功能介绍">3.2.4.1 功能介绍</h5> |
| <p>根据起始顶点、步骤（包括方向、边类型和过滤属性）和深度depth，查找从起始顶点出发depth步内可达的所有顶点。</p> |
| <blockquote> |
| <p>与K-neighbor基础版的不同在于：</p> |
| <ul> |
| <li>支持只统计邻居数量</li> |
| <li>支持边属性过滤</li> |
| <li>支持返回到达邻居的最短路径</li> |
| </ul> |
| </blockquote> |
| <h6 id="params-3">Params</h6> |
| <ul> |
| <li>source：起始顶点id，必填项</li> |
| <li>从起始点出发的Step，必填项，结构如下： |
| <ul> |
| <li>direction：表示边的方向（OUT,IN,BOTH），默认是BOTH</li> |
| <li>labels：边的类型列表</li> |
| <li>properties：通过属性的值过滤边</li> |
| <li>max_degree：查询过程中，单个顶点遍历的最大邻接边数目，默认为 10000 (注: 0.12版之前 step 内仅支持 degree 作为参数名, 0.12开始统一使用 max_degree, 并向下兼容 degree 写法)</li> |
| <li>skip_degree：用于设置查询过程中舍弃超级顶点的最小边数，即当某个顶点的邻接边数目大于 skip_degree 时，完全舍弃该顶点。选填项，如果开启时，需满足 <code>skip_degree >= max_degree</code> 约束，默认为0 (不启用)，表示不跳过任何点 (注意: 开启此配置后，遍历时会尝试访问一个顶点的 skip_degree 条边，而不仅仅是 max_degree 条边，这样有额外的遍历开销，对查询性能影响可能有较大影响，请确认理解后再开启)</li> |
| </ul> |
| </li> |
| <li>max_depth：步数，必填项</li> |
| <li>count_only：Boolean值，true表示只统计结果的数目，不返回具体结果；false表示返回具体的结果，默认为false</li> |
| <li>with_path：true表示返回起始点到每个邻居的最短路径，false表示不返回起始点到每个邻居的最短路径，选填项，默认为false</li> |
| <li>with_vertex，选填项，默认为false： |
| <ul> |
| <li>true表示返回结果包含完整的顶点信息（路径中的全部顶点） |
| <ul> |
| <li>with_path为true时，返回所有路径中的顶点的完整信息</li> |
| <li>with_path为false时，返回所有邻居的完整信息</li> |
| </ul> |
| </li> |
| <li>false时表示只返回顶点id</li> |
| </ul> |
| </li> |
| <li>limit：返回的顶点的最大数目，选填项，默认为10000000</li> |
| </ul> |

| <p>查找指定顶点集两两之间的最短路径</p> |
| <h6 id="params-11">Params</h6> |
| <ul> |
| <li>vertices：定义起始顶点，必填项，指定方式包括： |
| <ul> |
| <li>ids：通过顶点id列表提供起始顶点</li> |
| <li>label和properties：如果没有指定ids，则使用label和properties的联合条件查询起始顶点 |
| <ul> |
| <li>label：顶点的类型</li> |
| <li>properties：通过属性的值查询起始顶点</li> |
| </ul> |
| <blockquote> |
| <p>注意：properties中的属性值可以是列表，表示只要key对应的value在列表中就可以</p> |
| </blockquote> |
| </li> |
| </ul> |
| </li> |
| <li>step：表示从起始顶点到终止顶点走过的路径，必填项，Step的结构如下： |
| <ul> |
| <li>direction：表示边的方向（OUT,IN,BOTH），默认是BOTH</li> |
| <li>labels：边的类型列表</li> |
| <li>properties：通过属性的值过滤边</li> |
| <li>max_degree：查询过程中，单个顶点遍历的最大邻接边数目，默认为 10000 (注: 0.12版之前 step 内仅支持 degree 作为参数名, 0.12开始统一使用 max_degree, 并向下兼容 degree 写法)</li> |
| <li>skip_degree：用于设置查询过程中舍弃超级顶点的最小边数，即当某个顶点的邻接边数目大于 skip_degree 时，完全舍弃该顶点。选填项，如果开启时，需满足 <code>skip_degree >= max_degree</code> 约束，默认为0 (不启用)，表示不跳过任何点 (注意: 开启此配置后，遍历时会尝试访问一个顶点的 skip_degree 条边，而不仅仅是 max_degree 条边，这样有额外的遍历开销，对查询性能影响可能有较大影响，请确认理解后再开启)</li> |
| </ul> |
| </li> |
| <li>max_depth：步数，必填项</li> |
| <li>capacity：遍历过程中最大的访问的顶点数目，选填项，默认为10000000</li> |
| <li>with_vertex：true表示返回结果包含完整的顶点信息（路径中的全部顶点），false时表示只返回顶点id，选填项，默认为false</li> |

| <h6 id="params-13">Params</h6> |
| <ul> |
| <li>sources：定义起始顶点，必填项，指定方式包括： |
| <ul> |
| <li>ids：通过顶点id列表提供起始顶点</li> |
| <li>label和properties：如果没有指定ids，则使用label和properties的联合条件查询起始顶点 |
| <ul> |
| <li>label：顶点的类型</li> |

| <ul> |
| <li>direction：表示边的方向（OUT,IN,BOTH），默认是BOTH</li> |
| <li>labels：边的类型列表</li> |
| <li>properties：通过属性的值过滤边</li> |
| <li>max_degree：查询过程中，单个顶点遍历的最大邻接边数目，默认为 10000 (注: 0.12版之前 step 内仅支持 degree 作为参数名, 0.12开始统一使用 max_degree, 并向下兼容 degree 写法)</li> |
| <li>skip_degree：用于设置查询过程中舍弃超级顶点的最小边数，即当某个顶点的邻接边数目大于 skip_degree 时，完全舍弃该顶点。选填项，如果开启时，需满足 <code>skip_degree >= max_degree</code> 约束，默认为0 (不启用)，表示不跳过任何点 (注意: 开启此配置后，遍历时会尝试访问一个顶点的 skip_degree 条边，而不仅仅是 max_degree 条边，这样有额外的遍历开销，对查询性能影响可能有较大影响，请确认理解后再开启)</li> |
| </ul> |

| <p>适合查找各种复杂的路径集合，例如：</p> |
| <ul> |
| <li>社交网络中，查找看过张艺谋所导演的电影的用户关注的大V的路径（张艺谋—>电影—->用户—>大V）</li> |
| <li>风控网络中，查找多个高风险用户的直系亲属的朋友的路径（高风险用户—>直系亲属—>朋友）</li> |

| <p>根据一批起始顶点、边规则（包括方向、边的类型和属性过滤）和最大深度等条件查找符合条件的所有的路径</p> |
| <h6 id="params-15">Params</h6> |
| <ul> |
| <li>sources：定义起始顶点，必填项，指定方式包括： |
| <ul> |
| <li>ids：通过顶点id列表提供起始顶点</li> |
| <li>label和properties：如果没有指定ids，则使用label和properties的联合条件查询起始顶点 |
| <ul> |
| <li>label：顶点的类型</li> |
| <li>properties：通过属性的值查询起始顶点</li> |
| </ul> |
| <blockquote> |
| <p>注意：properties中的属性值可以是列表，表示只要key对应的value在列表中就可以</p> |
| </blockquote> |
| </li> |
| </ul> |
| </li> |
| <li>targets：定义终止顶点，必填项，指定方式包括： |
| <ul> |
| <li>ids：通过顶点id列表提供终止顶点</li> |
| <li>label和properties：如果没有指定ids，则使用label和properties的联合条件查询终止顶点 |
| <ul> |
| <li>label：顶点的类型</li> |
| <li>properties：通过属性的值查询终止顶点</li> |
| </ul> |
| <blockquote> |
| <p>注意：properties中的属性值可以是列表，表示只要key对应的value在列表中就可以</p> |
| </blockquote> |
| </li> |
| </ul> |
| </li> |
| <li>steps：表示从起始顶点走过的路径规则，是一组Step的列表。必填项。每个Step的结构如下： |
| <ul> |
| <li>direction：表示边的方向（OUT,IN,BOTH），默认是BOTH</li> |
| <li>labels：边的类型列表</li> |
| <li>properties：通过属性的值过滤边</li> |
| <li>max_times：当前step可以重复的次数，当为N时，表示从起始顶点可以经过当前step 1-N 次</li> |
| <li>max_degree：查询过程中，单个顶点遍历的最大邻接边数目，默认为 10000 (注: 0.12版之前 step 内仅支持 degree 作为参数名, 0.12开始统一使用 max_degree, 并向下兼容 degree 写法)</li> |
| <li>skip_degree：用于设置查询过程中舍弃超级顶点的最小边数，即当某个顶点的邻接边数目大于 skip_degree 时，完全舍弃该顶点。选填项，如果开启时，需满足 <code>skip_degree >= max_degree</code> 约束，默认为0 (不启用)，表示不跳过任何点 (注意: 开启此配置后，遍历时会尝试访问一个顶点的 skip_degree 条边，而不仅仅是 max_degree 条边，这样有额外的遍历开销，对查询性能影响可能有较大影响，请确认理解后再开启)</li> |
| </ul> |
| </li> |
| <li>with_ring：Boolean值，true表示包含环路；false表示不包含环路，默认为false</li> |
| <li>capacity：遍历过程中最大的访问的顶点数目，选填项，默认为10000000</li> |
| <li>limit：返回的路径的最大数目，选填项，默认为10</li> |
| <li>with_vertex：true表示返回结果包含完整的顶点信息（路径中的全部顶点），false时表示只返回顶点id，选填项，默认为false</li> |

| <p>根据一批起始顶点、多种边规则（包括方向、边的类型和属性过滤）和最大深度等条件查找符合条件的所有的路径终点的交集</p> |
| <h6 id="params-17">Params</h6> |
| <ul> |
| <li> |
| <p>sources：定义起始顶点，必填项，指定方式包括：</p> |
| <ul> |
| <li>ids：通过顶点id列表提供起始顶点</li> |
| <li>label和properties：如果没有指定ids，则使用label和properties的联合条件查询起始顶点 |
| <ul> |
| <li>label：顶点的类型</li> |
| <li>properties：通过属性的值查询起始顶点</li> |
| </ul> |
| <blockquote> |
| <p>注意：properties中的属性值可以是列表，表示只要key对应的value在列表中就可以</p> |
| </blockquote> |
| </li> |
| </ul> |
| </li> |
| <li> |
| <p>path_patterns：表示从起始顶点走过的路径规则，是一组规则的列表。必填项。每个规则是一个PathPattern</p> |
| <ul> |
| <li>每个PathPattern是一组Step列表，每个Step结构如下： |
| <ul> |
| <li>direction：表示边的方向（OUT,IN,BOTH），默认是BOTH</li> |
| <li>labels：边的类型列表</li> |
| <li>properties：通过属性的值过滤边</li> |
| <li>max_degree：查询过程中，单个顶点遍历的最大邻接边数目，默认为 10000 (注: 0.12版之前 step 内仅支持 degree 作为参数名, 0.12开始统一使用 max_degree, 并向下兼容 degree 写法)</li> |
| <li>skip_degree：用于设置查询过程中舍弃超级顶点的最小边数，即当某个顶点的邻接边数目大于 skip_degree 时，完全舍弃该顶点。选填项，如果开启时，需满足 <code>skip_degree >= max_degree</code> 约束，默认为0 (不启用)，表示不跳过任何点 (注意: 开启此配置后，遍历时会尝试访问一个顶点的 skip_degree 条边，而不仅仅是 max_degree 条边，这样有额外的遍历开销，对查询性能影响可能有较大影响，请确认理解后再开启)</li> |
| </ul> |
| </li> |
| </ul> |
| </li> |
| <li> |
| <p>capacity：遍历过程中最大的访问的顶点数目，选填项，默认为10000000</p> |
| </li> |
| <li> |
| <p>limit：返回的路径的最大数目，选填项，默认为10</p> |
| </li> |
| <li> |
| <p>with_path：true表示返回交点所在的路径，false表示不返回交点所在的路径，选填项，默认为false</p> |
| </li> |
| <li> |
| <p>with_vertex，选填项，默认为false：</p> |
| <ul> |
| <li>true表示返回结果包含完整的顶点信息（路径中的全部顶点） |
| <ul> |
| <li>with_path为true时，返回所有路径中的顶点的完整信息</li> |
| <li>with_path为false时，返回所有交点的完整信息</li> |
| </ul> |
| </li> |
| <li>false时表示只返回顶点id</li> |
| </ul> |
