Question

我试图通过API请求使角色工作的服务工作者。我希望该应用离线工作，我已经完成了以下配置：

    {
        "name": "api",
        "urls": ["https://x.com/**"],
        "cacheConfig": {
            "strategy": "performance",
            "maxSize": 20,
            "maxAge": "365d",
            "timeout": "5s"
        }
    }

以下是当我离线时xhr标签的样子：

这是用户请求的内容：

正如您所看到的那样，API要求用户不要解决。

这就是user在线时的响应：

试试这个：

转到您的应用程序标签 - ＆gt;清除存储 - ＆gt;清除网站数据。

从此处更改DataGroups数组：

{
    "name": "api",
    "urls": ["https://x.com/**"],
    "cacheConfig": {
        "strategy": "performance",
        "maxSize": 20,
        "maxAge": "365d",
        "timeout": "5s"
    }
}

对此：

"dataGroups": [
    {
      "name": "api-performance",
      "urls": [
        "/user" //<=========== I know you want all API calls to be cached, but try this first and see
      ],
      "cacheConfig": {
        "strategy": "performance",
        "maxSize": 100,
        "maxAge": "3d"
      }
    }
  ]

在PROD，
第一次访问该页面。
禁用网络
刷新页面

要离线处理Api数据，您必须使用离线存储（即在初始API调用后在Web浏览器中存储数据），最近我在我的应用程序中使用了Local Forage。找到以下链接：

如果您使用的是“策略”：“性能”，请删除超时属性

“数据组”：[ {

        "name": "TestApi",
        "urls": [
            "https://api.chucknorris.io/jokes/random",
            "https://localhost:4377/api/home/getNames/"
        ],
        "cacheConfig": {
            "strategy": "freshness",
            "maxSize": 20,
            "maxAge": "1h",
            "timeout": "5s"
        }
    },
    {
        "name": "TestAPI",
        "urls": [
            "https://localhost:4377/api/test/getList",
            "https://localhost:4377/api/template/start/"
        ],
        "cacheConfig": {
            "strategy": "performance",
            "maxSize": 20,
            "maxAge": "2h",
            "timeout": "5s"
        }
    }
]
