将我们的 Jira 内容索引到 Elaasticsearch 中以创建统一的数据源并使用文档级别安全性进行搜索。
在本文中，我们将回顾 Elastic Jira 原生连接器的一个用例。我们将使用一个模拟项目，其中一家银行正在开发一款汇款应用，需要将 Jira 中的信息集成到 Elastic 中。
原生连接器允许我们从票据、任务和其他文档中获取 Elastic 集群信息，集中数据并启用高级搜索功能。
使用此连接器的主要好处是：
- Jira 中的数据与 Elasticsearch 同步。
- 访问高级搜索功能。
- 文档级安全性 (DLS) 匹配源安全性。你只能搜索 Jira 中允许你查看的内容。
步骤
- 配置 Jira 连接器
- 将文档索引到 Elasticsearch
- 查询数据
- 文档级安全性 (document level security - DLS)
配置 Jira 连接器
首先，你需要从 Jira 获取 API token 以连接到 Elasticsearch。转到此链接了解如何创建它。
将其命名为 “elastic-connector”。它应该如下所示：
获取 token 并进入 Kibana 仪表板。然后，转到原生连接器并选择 New Jira Cloud connector。
https://<YOUR_KIBANA_URL>/app/enterprise_search/content/connectors/new_connector?service_type=jira&connector_type=native
用 Kibana 端点替换 YOUR_KIBANA_URL。
将连接器命名为 “bank”，然后点击 “Create and attach an index named bank”，即可创建一个同名的新索引。
完成了！现在我们需要配置我们的 Jira 数据。
由于我们不会使用自己的 SSL 证书，因此我们将保持 “Enable SSL” 关闭。
你可以在官方文档中查看每个字段的详细信息。
激活文档级安全性 (DLS)，以便你获得有权查看文档的用户和组。
正确配置连接器后，你可以继续同步数据，如下所示。从 Jira 获取数据可能需要几分钟。
- 完整内容（Full Content）：索引所有 Jira 文档。
- 增量内容（Incremental Content）：仅索引自上次完整内容同步以来的更改。
- 访问控制（Access Control）：在安全索引中索引 Jira 用户以激活 DLS。
我们可以检查连接器的概述来查看同步是否成功。
在 “Documents” 选项卡中，我们可以准确地看到使用连接器获取的数据。第一次同步的对象是：
- Projects
- Issues
- Attachments
将文档索引到 Elasticsearch
我们不仅限于跨连接器文档进行搜索。Elasticsearch 允许你使用单个查询搜索多个索引。
在我们的示例中，我们将其他文档索引到 galactic_documents 索引中，以了解搜索如何与多个数据源配合使用：
- GBFF 合规手册
- Galactic Banking App 用户指南
- 技术规格报告
但在索引之前，我们将为每个字段创建优化映射：
`
1. PUT /galactic_documents
2. {
3. "mappings": {
4. "properties": {
5. "document_id": {
6. "type": "keyword"
7. },
8. "title": {
9. "type": "text",
10. "fields": {
11. "raw": {
12. "type": "keyword"
13. }
14. }
15. },
16. "content": {
17. "type": "text"
18. },
19. "release_date": {
20. "type": "date",
21. "format": "yyyy-MM-dd"
22. },
23. "page_count": {
24. "type": "integer"
25. },
26. "tags": {
27. "type": "keyword"
28. }
29. }
30. }
31. }
`
配置映射后，我们现在可以索引：
1. POST galactic_documents/_bulk
2. { "index": { "_index": "galactic_documents", "_id": "1" } }
3. { "document_id": "GBFF-001", "title": "Compliance Manual of the GBFF", "content": "This document sets forth the compliance standards for intergalactic financial entities: Quantum-level data encryption to guarantee security in all transactions. Mandatory multi-factor authentication for all users and administrators. Quarterly reviews of security policies and access audit logs.", "release_date": "2024-01-01", "page_count": 5, "tags": ["compliance", "security"] }
4. { "index": { "_index": "galactic_documents", "_id": "2" } }
5. { "document_id": "GBFF-002", "title": "User Guide for the Galactic Banking App", "content": "Welcome to the Galactic Banking application by Interstellar Finance Corp. Here you can: Transfer galactic credits to any registered account across the Milky Way. Check your balance and manage your investments in real-time. Access interplanetary loans with ease. For your security, use multi-factor authentication each time you log in.", "release_date": "2024-01-01", "page_count": 3, "tags": ["user guide", "application"] }
6. { "index": { "_index": "galactic_documents", "_id": "3" } }
7. { "document_id": "GBFF-003", "title": "Technical Specifications Report - Galactic Banking Project", "content": "This report details the technical architecture of the Galactic Banking application: Microservices-based backend for scalability and performance. Secure communication protocols utilizing quantum encryption. Transaction management adapted to environments with gravity variations and time dilation.", "release_date": "2024-01-01", "page_count": 7, "tags": ["technical", "specifications", "architecture"] }
查询数据
现在我们有了 Jira 对象和文档，我们可以一起搜索它们。
1. GET bank,galactic_documents/_search
2. {
3. "query": {
4. "multi_match": {
5. "query": "galactic moon",
6. "fields": [
7. "content",
8. "title",
9. "*description",
10. "*summary"
11. ]
12. }
13. }
14. }
查询 “galactic moon” 将为我们获取 Jira 对象和我们索引的文档：

如果文档太长，你可以将选项 _source 添加到查询中，以仅包含你需要的字段。如果你只想删除一些字段，我们将在本系列的第二部分介绍该选项。
文档级安全性 (DLS)
我们现在将配置文档级安全性 (DLS)，以将 Jira 权限与 Elasticsearch 中的权限相匹配，以便用户搜索时只能看到他们在 Jira 中被允许看到的内容。
首先，我们将转到 Elastic Cloud 中连接器的控制面板，然后单击 Access Control Sync。
此同步将带来 Jira 用户的访问和权限信息。为了测试这一点，我创建了另一个 Jira 板（board），但用户 “Gustavo” 无权访问该板。
让我们开始检查新板中的文档是否存在：
1. GET bank/_search
2. {
3. "_source": ["Issue.summary"],
4. "query": {
5. "match": {
6. "Issue.project.name": "Marketing Mars"
7. }
8. }
9. }
我们可以有效地看到以下问题：
1. {
2. "took": 2,
3. "timed_out": false,
4. "_shards": {
5. "total": 2,
6. "successful": 2,
7. "skipped": 0,
8. "failed": 0
9. },
10. "hits": {
11. "total": {
12. "value": 3,
13. "relation": "eq"
14. },
15. "max_score": 0.7473189,
16. "hits": [
17. {
18. "_index": "bank",
19. "_id": "Marketing Mars-MM-1",
20. "_score": 0.7473189,
21. "_source": {
22. "Issue": {
23. "summary": "Conquer Mars"
24. }
25. }
26. },
27. {
28. "_index": "bank",
29. "_id": "Marketing Mars-MM-3",
30. "_score": 0.7473189,
31. "_source": {
32. "Issue": {
33. "summary": "Conquering Earth"
34. }
35. }
36. },
37. {
38. "_index": "bank",
39. "_id": "Marketing Mars-MM-2",
40. "_score": 0.7473189,
41. "_source": {
42. "Issue": {
43. "summary": "Conquer the moon"
44. }
45. }
46. }
47. ]
48. }
49. }
但是，由于用户 “Gustavo” 没有访问权限，因此他应该无法看到它们。
让我们在 ACL 过滤器索引中查找用户的文档以查看他们的权限。
GET .search-acl-filter-bank/_search
响应：
1. {
2. "_index": ".search-acl-filter-bank",
3. "_id": "63c04b092341bff4fff6e0cb",
4. "_score": 1,
5. "_source": {
6. "created_at": "2024-11-01T23:19:35.784996+00:00",
7. "id": "63c04b092341bff4fff6e0cb",

10. "account_id": "account_id:63c04b092341bff4fff6e0cb",
11. "email_address": null,
12. "display_name": "name:Gustavo",
13. "locale": "locale:en_US"
14. },
15. "query": {
16. "template": {
17. "source": """{
18. "bool": {
19. "should": [
20. {
21. "bool": {
22. "must_not": {
23. "exists": {
24. "field": "_allow_access_control"
25. }
26. }
27. }
28. },
29. {
30. "terms": {
31. "_allow_access_control.enum": {{#toJson}}access_control{{/toJson}}
32. }
33. }
34. ]
35. }
36. }""",
37. "params": {
38. "access_control": [
39. "account_id:63c04b092341bff4fff6e0cb",
40. "group_id:d3f28403-7e99-4262-8f11-77a75bcd33d8",
41. "role_key:jira-software"
42. ]
43. }
44. }
45. }
46. }
47. }
该索引包括用户 ID 及其所有 Jira 组。我们需要将用户访问控制中的内容与每个文档中的字段 _allowed_access_control 进行匹配。
我们将使用以下命令为 Gustavo 创建 API 密钥。你必须从上一步复制 query.template 值：
1. POST /_security/api_key
2. {
3. "name": "gustavo",
4. "expiration": "30d",
5. "role_descriptors": {
6. "jira-role": {
7. "index": [
8. {

请注意，我们仅通过此选项授予对本文中索引的访问权限。
为 Gustavo 创建 API 密钥的响应如下：
1. {
2. "id": "yLa1FJMBU4bZPaw5Stnl",
3. "name": "gustavo",
4. "expiration": 1733811245816,
5. "api_key": "UrGdsnDFSyGxjQvLayw5jQ",
6. "encoded": "eUxhMUZKTUJVNGJaUGF3NVN0bmw6VXJHZHNuREZTeUd4alF2TGF5dzVqUQ=="
7. }
你可以使用 curl 来测试我们是否可以使用 API KEY 运行搜索，并且它不会从 Marketing board 获取信息，因为 Gustavo 无权访问它。
1. curl --location --request GET 'https://interstellar-finance-corp.es.us-central1.gcp.cloud.es.io/bank/_search' \
2. --header 'Authorization: ApiKey eUxhMUZKTUJVNGJaUGF3NVN0bmw6VXJHZHNuREZTeUd4alF2TGF5dzVqUQ==' \
3. --header 'Content-Type: application/json' \
4. --data '{
5. "_source": ["Issue.summary"],
6. "query": {
7. "match": {
8. "Issue.project.name": "Marketing Mars"
9. }
10. }
11. }'
响应：
1. {
2. "took": 0,
3. "timed_out": false,
4. "_shards": {
5. "total": 1,
6. "successful": 1,
7. "skipped": 0,
8. "failed": 0
9. },
10. "hits": {
11. "total": {
12. "value": 0,
13. "relation": "eq"
14. },
15. "max_score": null,
16. "hits": []
17. }
18. }
我们可以看到，Gustavo 没有获得任何信息，因为他没有访问权限。现在，让我们用他被允许查看的 board 文件进行测试：
1. curl --location --request GET 'https://interstellar-finance-corp.es.us-central1.gcp.cloud.es.io/bank/_search?pretty=true' \
2. --header 'Authorization: ApiKey eUxhMUZKTUJVNGJaUGF3NVN0bmw6VXJHZHNuREZTeUd4alF2TGF5dzVqUQ==' \
3. --header 'Content-Type: application/json' \
4. --data '{
5. "_source": ["Issue.summary"],
6. "query": {
7. "match": {
8. "Issue.project.name": "Galactic Banking Project"
9. }
10. }
11. }'
响应：
1. {
2. "took" : 7,
3. "timed_out" : false,
4. "_shards" : {
5. "total" : 2,
6. "successful" : 2,

结论
如你所见，将 Elasticsearch 与 Jira 集成有许多好处，例如能够对你正在处理的所有项目进行统一搜索，以及能够在多个数据源中运行更高级的搜索。添加的 DLS 是一种快速简便的方法，可确保用户保持他们在原始源中已有的访问权限。
