Question

我有一个json文件，想用jq解析它，以便在输出中显示如下内容：

.issues.keys .project.self .fixVersions.id .fixVersions.name
.fixVersions.description .resolution.description .resolution.name .versions.name .summary.summary

这是json部分：

[
  {
    "expand": "schema,names",
    "startAt": 0,
    "maxResults": 50,
    "total": 56,
    "issues": [
      {
        "key": "AXL-2766",
        "fields": {
          "issuetype": {
            "self": "https://jira/rest/api/2/issuetype/1",
            "description": "desc.",
          },
          "project": {
            "self": "https://jira/rest/api/2/project/15770",
            "avatarUrls": {
              "48x48": "https://jira/secure/projectavatar?avatarId=15683",
            }
          },
          "fixVersions": [
            {
              "self": "https://jira/rest/api/2/version/18167",
              "description": "description1",
              "name": "0.2.0",
            }
          ],
          "resolution": {
            "self": "https://jira/rest/api/2/resolution/1",
            "description": "description2",
            "name": "Fixed"
          },
          "watches": {
            "self": "https://jira/rest/api/2/issue/AXL-2766/watchers",
          },
          "created": "2019-03-04T01:10:07.000-0500",
          "priority": {
            "self": "https://jira/rest/api/2/priority/2",
          },
          "customfield_10420": null,
          "customfield_12322": {
            "self": "https://jira/rest/api/2/customFieldOption/10644",
          },
          "versions": [
            {
              "self": "https://jira/rest/api/2/version/18165",
              "id": "18165",
              "description": "",
              "name": "0.0"
            }
          ],
          "issuelinks": [],
          "assignee": {
            "emailAddress": "aaa@domain.test"
            },
            "displayName": "user",
          },
          "updated": "2019-03-04T05:47:13.000-0500",
          "status": {
            "self": "https://jira/rest/api/2/status/5",
            "description": "description3.",
            "statusCategory": {
              "colorName": "green",
              "name": "Done"
            }
          },
          "summary": "summary",
          "creator": {
            "self": "https://jira/rest/api/2/user?username=user",
            "emailAddress": "user.@domain.net"
          },
          "subtasks": [],
          "reporter": {
          "self": "https://jira/rest/api/2/user?username=user",
            "emailAddress": "user.@domain.net",
          },
          "aggregateprogress": {
            "progress": 1800,
          },
          "customfield_10122": null,
          "progress": {
            "progress": 1800,
          },
          "votes": {
            "self": "https://jira/rest/api/2/issue/AXL-2766/votes",
          }
        }
      }
]

我已经尝试过，但是一直坚持下去：

。[] | {issues：.issues，字段：[.fields .fixVersions .name]}

P.S json文件可能已损坏，因为我已从那里删除了一些私人信息：）

（假设您的json是固定/有效）

如果您不仅限于使用jq，请允许我为您提供替代解决方案：使用 jtc unix实用程序，可以轻松遍历json路径（下标看起来像在编程语言，例如类似于Python）。

因此，如果您的json结构是固定的，那么为了转储所有必需的值，请为每个项提供一个遍历路径：

bash $ jtc -w'[0][issues][0][key]' -w'[0][issues][0][fields][project][self]' -w'[0][issues][0][fields][fixVersions][0][name]' -w'[0][issues][0][fields][fixVersions][0][description]' -w'[0][issues][0][fields][resolution][description]' -w'[0][issues][0][fields][resolution][name]' -w'[0][issues][0][summary]' file.json
"AXL-2766"
"https://jira/rest/api/2/project/15770"
"0.2.0"
"description1"
"description2"
"Fixed"
"summary"
bash $

缩短命令：路径[0][issues][0]的公共部分（每次走动中都存在）可以与可变部分分开，这将产生较短的cli，结果相同：

bash $ jtc -x'[0][issues][0]' -y'[key]' -y'[fields][project][self]' -y'[fields][fixVersions][0][name]' -y'[fields][fixVersions][0][description]' -y'[fields][resolution][description]' -y'[fields][resolution][name]' -y'[summary]' file.json 
"AXL-2766"
"https://jira/rest/api/2/project/15770"
"0.2.0"
"description1"
"description2"
"Fixed"
"summary"
bash $

如果您的示例只是更大json的一部分（即未从根目录显示），则将初始部分（[0][issues][0]）替换为使用搜索键的部分：<issues>l[0]。
