To obtain system information, you can utilize the runtime package and os package in the Go language.<\/p>\n

Here are some ways to obtain system information:<\/p>\n

    \n
  1. Obtain the name and architecture of the operating system:<\/li>\n<\/ol>\n
    package<\/span> main\r\n\r\nimport<\/span> (\r\n\t\"fmt\"<\/span>\r\n\t\"runtime\"<\/span>\r\n)\r\n\r\nfunc<\/span> main<\/span>()<\/span><\/span> {\r\n\tfmt.Println(\"\u64cd\u4f5c\u7cfb\u7edf\uff1a\"<\/span>, runtime.GOOS)\r\n\tfmt.Println(\"\u67b6\u6784\uff1a\"<\/span>, runtime.GOARCH)\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Retrieve the number of CPU cores:<\/li>\n<\/ol>\n
      package<\/span> main\r\n\r\nimport<\/span> (\r\n\t\"fmt\"<\/span>\r\n\t\"runtime\"<\/span>\r\n)\r\n\r\nfunc<\/span> main<\/span>()<\/span><\/span> {\r\n\tfmt.Println(\"CPU\u6838\u5fc3\u6570\uff1a\"<\/span>, runtime.NumCPU())\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Get memory information.<\/li>\n<\/ol>\n
        package<\/span> main\r\n\r\nimport<\/span> (\r\n\t\"fmt\"<\/span>\r\n\t\"runtime\"<\/span>\r\n)\r\n\r\nfunc<\/span> main<\/span>()<\/span><\/span> {\r\n\tvar<\/span> memStats runtime.MemStats\r\n\truntime.ReadMemStats(&memStats)\r\n\r\n\tfmt.Println(\"\u603b\u5206\u914d\u7684\u5185\u5b58\uff1a\"<\/span>, memStats.TotalAlloc)\r\n\tfmt.Println(\"\u5806\u5185\u5b58\u4f7f\u7528\u91cf\uff1a\"<\/span>, memStats.HeapAlloc)\r\n\tfmt.Println(\"\u5806\u5185\u5b58\u91ca\u653e\u91cf\uff1a\"<\/span>, memStats.HeapReleased)\r\n\tfmt.Println(\"\u5806\u5185\u5b58\u5bf9\u8c61\u6570\uff1a\"<\/span>, memStats.HeapObjects)\r\n}\r\n<\/code><\/pre>\n
          \n
        1. Accessing environmental variables:<\/li>\n<\/ol>\n
          package<\/span> main\r\n\r\nimport<\/span> (\r\n\t\"fmt\"<\/span>\r\n\t\"os\"<\/span>\r\n)\r\n\r\nfunc<\/span> main<\/span>()<\/span><\/span> {\r\n\tenvVars := os.Environ()\r\n\tfor<\/span> _, envVar := range<\/span> envVars {\r\n\t\tfmt.Println(envVar)\r\n\t}\r\n}\r\n<\/code><\/pre>\n
          These methods can assist you in obtaining information about the operating system, hardware, and environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
