范围超过JSON数组时无法迭代所有索引

Question

I'm creating a standalone mockserver with JSON file as my input (request and response) for integration testing. I was able to serve first request only.

// MockServices ...
type MockServices struct {
    Request  string `json:"request"`
    Response string `json:"response"`
}

func main() {
r := getMockServices()

for i, s := range r {
    for i >= 0 {
        // fmt.Println(i)
        // fmt.Println(s.Request)
        http.HandleFunc(s.Request, func(w http.ResponseWriter, r *http.Request) {
            // not serving remaing endpoints
            w.Write([]byte(s.Response))
        })

        if err := http.ListenAndServe(":8080", nil); err != nil {
            panic(err)
        }
    }
}}

Any help greatly appreciated.

Thanks in advance

There are quite a few issues:

• https://golang.org/pkg/net/http/#ListenAndServe always returns a Non-nil error
• You're attempting to bind to same port in a loop
• You're attempting to bind in ANOTHER loop based on the index of the mock response
