gland debug. Got a connection, launched process

此问题是由于升级 macos sonoma 14.2.1 引起的
解决办法，重新安装xcode

rm -rf /Library/Developer/CommandLineTools
xcode-select --install

gin跨域

一凡 — Thu, 26 Dec 2019 03:17:00 GMT

新增中间件cors

func Cors() gin.HandlerFunc {
 return func(c *gin.Context) {
 method := c.Request.Method

      c.Header("Access-Control-Allow-Origin", "*")   //必选
      c.Header("Access-Control-Allow-Headers", "*")  //可选  如果request有header, 必选
      //c.Header("Access-Control-Allow-Credentials", "true")  //可选
      //c.Header("Access-Control-Allow-Methods", "*")  //可选
      //c.Header("Access-Control-Expose-Headers", "*")  //可选

      //放行所有OPTIONS方法
 if method == "OPTIONS" {
 c.AbortWithStatus(http.StatusOK)
      }
 // 处理请求
 c.Next()
   }
}

在router里增加cors，必须在group之前，全局设置
```
r.Use(gin.Logger(), gin.Recovery(), cors.Cors())
```

测试代码，header设置不能多于cors设置

html>
lang="en">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<link type="test/css" href="css/style.css" rel="stylesheet">
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js">script>  
<script type="text/javascript">
 $(function(){
 $("#cors").click(
 function(){
 $.ajax({
 headers:{
 "Content-Type":"application/json;charset=UTF-8",
 "Access":"adsad",
 "Access-Token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6InRlc3QiLCJwYXNzd29yZCI6InRlc3QxMjM0NTYiLCJleHAiOjE1NzczMzY3MTIsImlzcyI6Imdpbi1ibG9nIn0.wMlQXqZO2V0LR-FIgDh45LWI0OYMYi6an_NvRmF0Nug"
 },
 url:"http://127.0.0.1:8000/api/v1/articles",
 success:function(data){
 console.log("start");
 console.log(data);
            }
         })
      });
   });
script>
<body>
   <input type="button" id="cors" value="core跨域测试">
body>

请求的headers数量、名称与cors里的设置需要严格对应，不然报错如下
Access to XMLHttpRequest at 'http://127.0.0.1:8000/api/v1/articles' from origin 'http://localhost:9999' has been blocked by CORS policy: Request header field access is not allowed by Access-Control-Allow-Headers in preflight response.

gin-swagger鉴权（auth）

一凡 — Mon, 23 Dec 2019 08:08:00 GMT

1、在main函数中增加全局配置，其中@name就是你确定的鉴权参数名，我的是token, @in header 说明参数放在header，你的鉴权代码需要从header中获取

// @title gin-blog API
// @version 0.0.1
// @description This is a gin blog example
// @securityDefinitions.apikey ApiKeyAuth
// @in header
// @name token
// @BasePath /

2、在具体的handler里添加如下注释，此处的ApiKeyAuth和main中的apike对应，切记不要修改

// @Security ApiKeyAuth

3、swagger页面如下：

4、添加token后，后续所有有鉴权接口的header里自动携带token
