        {

          "count": 5818
        },
        {
          "val": "MAJOR",
          "count": 1459
        },
        {
          "val": "BLOCKER",
          "count": 1286
        },
        {
          "val": "MINOR",
          "count": 1163
        },
        {
          "val": "INFO",
          "count": 331
        }
      ]
    }
  ]
}

现在我要提取密钥："total", "issues", "facets.values"。

所以我在我的 bash 脚本中尝试这个：

#!/bin/bash
readonly BASE_URL=http://my_host:9111/api
readonly PROJECT_KEY=my_project

read totalIssues facetsArr issuesArr < <(echo $(curl -XGET $BASE_URL/issues/search\?componentKeys\=$PROJECT_KEY\&facets\=severities\&p\=1\&ps\=1 |
                       jq -r '.total, .issues[], .facets[].values'))
echo "total      : $totalIssues"
echo "facetsArr     : $facetsArr"
echo "issuesArr  : $issuesArr"

但结果是：

total      : 10057
facetsArr  : {
issuesArr  : "key": "AX0NVCNfENszTAxEgX5e", "rule": "java:S122", "severity": "MINOR", "component": "MyFile.java", "project": "myProject", "line": 241, "hash": "b68d3b4b390c81e2714d263b31acdd08", "textRange": { "startLine": 241, "endLine": 241, "startOffset": 0, "endOffset": 46 }, "flows": [], "status": "OPEN", "message": "At most one statement is allowed per line, but 2 statements were found on this line.", "effort": "1min", "debt": "1min", "author": "eugeniur", "tags": [ "convention" ], "creationDate": "2021-11-11T06:40:05+0200", "updateDate": "2021-11-11T06:40:05+0200", "type": "CODE_SMELL", "scope": "MAIN" } [ { "val": "CRITICAL", "count": 5818 }, { "val": "MAJOR", "count": 1459 }, { "val": "BLOCKER", "count": 1286 }, { "val": "MINOR", "count": 1163 }, { "val": "INFO", "count": 331 } ]

为什么“facetsArr”的值不正确？

“facetsArr”必须是：

facetsArr  : [ { "val": "CRITICAL", "count": 5818 }, { "val": "MAJOR", "count": 1459 }, { "val": "BLOCKER", "count": 1286 }, { "val": "MINOR", "count": 1163 }, { "val": "INFO", "count": 331 } ]

Answer 1

1. 使用字符串操作在每个值之间插入换行符 (\n)，现在每行都包含您要捕获的值
2. 引用jq 命令，因为它可能包含空格^[info]
3. 将IFS 设置为换行符^[info]
4. 使用read -d '' ^[docs]

   -d delim

   继续直到读取 DELIM 的第一个字符，而不是 比换行符

---

应用这些修复，脚本将如下所示：

IFS=$'\n'
read -r -d '' totalIssues facetsArr issuesArr <<< "$( jq -r '"\(.total)\n\(.facets[].values)\n\(.issues[])"' input)"
echo "total      : $totalIssues"
echo "facetsArr  : $facetsArr"
echo "issuesArr  : $issuesArr"

^{注意：我已将 curl 命令替换为名为 input 的实际文件，其中包含 OP 的 JSON}

---

输出将是：

total      : 10057
facetsArr  : [{"val":"CRITICAL","count":5818},{"val":"MAJOR","count":1459},{"val":"BLOCKER","count":1286},{"val":"MINOR","count":1163},{"val":"INFO","count":331}]
issuesArr  : {"key":"AX0NVCNfENszTAxEgX5e","rule":"java:S122","severity":"MINOR","component":"my_project:SomeFile.java","project":"my_project","line":241,"hash":"1111111111","textRange":{"startLine":241,"endLine":241,"startOffset":0,"endOffset":46},"flows":[],"status":"OPEN","message":"At most one statement is allowed per line, but 2 statements were found on this line.","effort":"1min","debt":"1min","author":"eugeniur","tags":["convention"],"creationDate":"2021-11-11T06:40:05+0200","updateDate":"2021-11-11T06:40:05+0200","type":"CODE_SMELL","scope":"MAIN"}

Answer 2

效率稍低，但只解析（小）响应 3 次会简单得多。

#!/bin/bash
readonly BASE_URL=http://my_host:9111/api
readonly PROJECT_KEY=my_project

response=$(curl -XGET "$BASE_URL/issues/search?componentKeys=$PROJECT_KEY&facets=severities&p=1&ps=1")

total=$(jq '.total' <<< "$response")
issues=$(jq '.issues' <<< "$response")
facets=$(jq '.facets[].values' <<< "$response")

# ...

那么您不必担心使用jq 构造单个输出，而bash 无论如何都必须解析。

（我有意将issues 的值保留为JSON 数组，而不是issues 的流，以防数组中存在多个对象。）
