Question

我无法执行go程序。我发现此示例使用go实现斜杠命令：https://medium.com/@emilygoldfein/creating-slack-slash-commands-using-go-3cea3b3f0920

我能够构建并运行该程序，但是当我进入松弛状态并在松弛状态中输入/ weather 90210时，出现错误：/ weather失败，并显示错误“ dispatch_failed”，并且在 ngrok我收到错误：POST / receve 404 Not found

代码如下：

```package main

import (
"encoding/json"
"fmt"
"log"
"math"
"net/http"
"os"

"github.com/joho/godotenv"
"github.com/nlopes/slack"
)

// APIResponse maps to the JSON response from the Open Weather Map API
type APIResponse struct {
Summary []struct {
    ID          int    `json:"id"`
    Main        string `json:"main"`
    Description string `json:"description"`
    Icon        string `json:"icon"`
} `json:"weather"`
Weather struct {
    Temp     float64 `json:"temp"`
    Humidity int     `json:"humidity"`
    Pressure int     `json:"pressure"`
    TempMin  float64 `json:"temp_min"`
    TempMax  float64 `json:"temp_max"`
} `json:"main"`
Location string `json:"name"`
}

func main() {
// Load environment variables
err := godotenv.Load("environment.env")
if err != nil {
    log.Fatal("Error loading .env file")
}

http.HandleFunc("/receive", slashCommandHandler)
fmt.Println("[INFO] Server listening")
http.ListenAndServe(":8080", nil)
}

func slashCommandHandler(w http.ResponseWriter, r *http.Request) {
s, err := slack.SlashCommandParse(r)

if err != nil {
    w.WriteHeader(http.StatusInternalServerError)
    return
}

if !s.ValidateToken(os.Getenv("SLACK_VERIFICATION_TOKEN")) {
    w.WriteHeader(http.StatusUnauthorized)
    return
}

switch s.Command {
case "/weather":
    params := &slack.Msg{Text: s.Text}
    zipCode := params.Text

    // Generates API request URL with zip code and API key
    url := fmt.Sprintf("https://api.openweathermap.org/data/2.5/weather?zip=%v&APPID=%v&units=imperial", zipCode, os.Getenv("API_KEY"))

    req, err := http.NewRequest("GET", url, nil)
    if err != nil {
        log.Fatal(err)
    }

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        log.Fatal(err)
    }

    defer resp.Body.Close()

    if resp.StatusCode == http.StatusOK {
        apiResponse := &APIResponse{}

        err = json.NewDecoder(resp.Body).Decode(&apiResponse)
        if err != nil {
            log.Fatal(err)
        }

        // Round temp to nearest integer
        roundedTemp := math.Round(apiResponse.Weather.Temp)

        response := fmt.Sprintf("The weather in %v is %v. The temperature is %v\u00B0 F.", apiResponse.Location, apiResponse.Summary[0].Description, roundedTemp)
        w.Write([]byte(response))
    }

default:
    w.WriteHeader(http.StatusInternalServerError)
    return
}
}```

我正在运行Go 1.14

这是我的ngrok输出：〜％ngrok http 8080 ngrok by @inconshreveable（Ctrl + C退出）
