Go 仅使用公共 api 对 alexedwardsscs 进行简单测试

我在你的代码里看到了

ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
    // ...
}))

sessionManager.LoadAndSave(ts) // this line is incorrect

您正在try 通过测试服务器(ts)到sessionManager.LoadAndSave.这不会起作用，因为sessionManager.LoadAndSave需要http.Handler，而ts的类型是*httptest.Server，而不是http.Handler.

相反，您应该在创建测试服务器之前将实际处理程序传递给sessionManager.LoadAndSave.

为此，在将其传递给httptest.NewServer之前，您将用sessionManager.LoadAndSave包装实际的处理程序函数(它确实返回http.Handler).

handler := sessionManager.LoadAndSave(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
    // ... logic here ...
}))

ts := httptest.NewServer(handler)

这将通过用sessionManager.LoadAndSave中间件包装您的实际处理程序函数来创建一个新的处理程序.然后，该包装的处理程序被传递到httptest.NewServer.

如果你把所有这些都放在一起:

package main

import (
    "fmt"
    "github.com/alexedwards/scs/v2"
    "github.com/stretchr/testify/assert"
    "io"
    "log"
    "net/http"
    "net/http/httptest"
    "testing"
)

func TestScs_SetGetIsSame2(t *testing.T) {
    sessionManager := scs.New()

    // Create a handler and wrap it using sessionManager.LoadAndSave
    handler := sessionManager.LoadAndSave(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(w, "Hello, client")
        expected := true
        sessionManager.Put(r.Context(), "key", expected)
        actual := sessionManager.GetBool(r.Context(), "key")
        assert.Equal(t, expected, actual)
    }))

    // Create a test server with the handler
    ts := httptest.NewServer(handler)
    defer ts.Close()

    // Make a request to the server
    res, err := http.Get(ts.URL)
    if err != nil {
        log.Fatal(err)
    }

    // Read the response body
    greeting, err := io.ReadAll(res.Body)
    res.Body.Close()
    if err != nil {
        log.Fatal(err)
    }

    // Print the response body
    fmt.Printf("%s", greeting)
}
