问题

Vscode 对 go 代码要求过于严苛，可能会出现闪烁等问题。

解决

打开 settings.json 文件，配置如下

{
    "go.inferGopath": false,
    "go.lintFlags": [
    "-min_confidence=.8"
    ],
}

一份具体的配置：

{
        "go.useLanguageServer": true,
        "timeline.excludeSources": [],
        "[go]": {
            "editor.snippetSuggestions": "none",
            "editor.formatOnSave": true,
            "editor.codeActionsOnSave": {
                "source.organizeImports": true
            }
        },

        "gopls": {
            "completeUnimported": true,
            "usePlaceholders": true,
            "completionDocumentation": true,
            "deepCompletion": true, 
            "matcher": "fuzzy",
            "hoverKind": "SynopsisDocumentation" // No/Synopsis/Full, default Synopsis
        },

        "files.eol": "\n", // formatting only supports LF line endings


        "go.languageServerExperimentalFeatures": {
            "format": true,
            "autoComplete": true,
            "rename": true,
            "goToDefinition": true,
            "hover": true,
            "signatureHelp": true,
            "goToTypeDefinition": true,
            "goToImplementation": true,
            "documentSymbols": true,
            "workspaceSymbols": true,
            "findReferences": true,
            "diagnostics": false
        },
        "emmet.excludeLanguages": [

            "markdown"
        ],
        "go.addTags": {

    },
    "go.inferGopath": false,
    "go.lintFlags": [
        "-min_confidence=.8"
        ],
    }

扩展

当go的项目目录不是根目录时，可能引入的包会爆红，无法跳转

解决方法是：在根目录建一个.vscode目录,里面放一个settings.json文件
-.vscode
—settings.json

settings.json文件内容如下：

{
    "go.inferGopath": false,
    "gopls": {
        "experimentalWorkspaceModule": true
    },

}

重启vscode，解决
