下面是我尝试解码的JSON的一个示例:

{
  "results": [
    {
      "Modified": "2022-12-30T22:27:00",
      "Published": "2022-12-23T15:15:00",
      "access": {},
      "assigner": "cve@mitre.org",
      "cvss": null,
      "cwe": "CWE-77",
      "id": "CVE-2022-46642",
      "impact": {},
      "last-modified": "2022-12-30T22:27:00",
      "references": [
        "https://github.com/CyberUnicornIoT/IoTvuln/blob/main/d-link/dir-846/D-Link%20dir-846%20SetAutoUpgradeInfo%20command%20injection%20vulnerability.md",
        "https://www.dlink.com/en/security-bulletin/"
      ],
      "summary": "D-Link DIR-846 A1_FW100A43 was discovered to contain a command injection vulnerability via the auto_upgrade_hour parameter in the SetAutoUpgradeInfo function.",
      "vulnerable_configuration": [
        "cpe:2.3:o:dlink:dir-846_firmware:100a43:*:*:*:*:*:*:*",
        "cpe:2.3:h:dlink:dir-846:a1:*:*:*:*:*:*:*"
      ],
      "vulnerable_configuration_cpe_2_2": [],
      "vulnerable_product": [
        "cpe:2.3:o:dlink:dir-846_firmware:100a43:*:*:*:*:*:*:*"
      ]
    },

(the JSON文件继续下一个{ "Modified"...
我搜索了一个解决方案,代码如下所示:
该结构体

struct CVE : Decodable
{
    var id : String
    var cvss : String? = nil
    var Modified : String
    var summary : String
    
}
struct CVEdata : Decodable
{
    var results : [CVE]
}

JSON解码函数

func jsonDataRequest () async
    {
        if let url = URL(string: "https://cve.circl.lu/api/query?time_start=30-12-2022,time_end=31-12-2022")
        {
             do
             {
                 let (data, _) = try await URLSession.shared.data(from: url)
                 arrCVE = try JSONDecoder().decode([CVEdata].self, from: data)
             }
             catch
            {
                 print(error)
            }
         }
    }
}

如果上面的算法是正确的,我如何访问arrCVE变量中的数据?我已经尝试过字典的for循环,但我认为问题出在解码行的某个地方。谢谢

这里的问题是JSON的顶层容器不是数组,因此解码类型应该是CVEData.self(而不是[CVEData].self)。
然后您可以通过arrCVE.results访问CVE对象列表。
不要忘记,必须相应地重新声明arrCVE
var arrCVE: CVEdata?
