计算类似的数组值

Question

我试图学习Go（或Golang）并且似乎无法做到正确。我有2个文本文件，每个文件包含一个单词列表。我试图计算两个文件中存在的单词数量。

到目前为止，这是我的代码：

package main

import (
    "fmt"
    "log"
    "net/http"
    "bufio"
)

func stringInSlice(str string, list []string) bool {
    for _, v := range list {
        if v == str {
            return true
        }
    }
    return false
}

func main() {
    // Texts URL
    var list = "https://gist.githubusercontent.com/alexcesaro/c9c47c638252e21bd82c/raw/bd031237a56ae6691145b4df5617c385dffe930d/list.txt"
    var url1 = "https://gist.githubusercontent.com/alexcesaro/4ebfa5a9548d053dddb2/raw/abb8525774b63f342e5173d1af89e47a7a39cd2d/file1.txt"

    //Create storing arrays
    var buffer [2000]string
    var bufferUrl1 [40000]string

    // Set a sibling counter
    var sibling = 0

    // Read and store text files
    wordList, err := http.Get(list)
    if err != nil {
        log.Fatalf("Error while getting the url : %v", err)
    }
    defer wordList.Body.Close()

    wordUrl1, err := http.Get(url1)
    if err != nil {
        log.Fatalf("Error while getting the url : %v", err)
    }
    defer wordUrl1.Body.Close()

    streamList := bufio.NewScanner(wordList.Body)
    streamUrl1 := bufio.NewScanner(wordUrl1.Body)

    streamList.Split(bufio.ScanLines)
    streamUrl1.Split(bufio.ScanLines)

    var i = 0;
    var j = 0;

    //Fill arrays with each lines
    for streamList.Scan() {
        buffer[i] = streamList.Text()
        i++
    }
    for streamUrl1.Scan() {
        bufferUrl1[j] = streamUrl1.Text()
        j++
    }

    //ERROR OCCURRING HERE :
    // This code if i'm not wrong is supposed to compare through all the range of bufferUrl1 -> bufferUrl1 values with buffer values, then increment sibling and output FIND
    for v := range bufferUrl1{
        if stringInSlice(bufferUrl1, buffer) {
            sibling++
            fmt.Println("FIND")
        }
    }

    // As a testing purpose thoses lines properly paste both array
    // fmt.Println(buffer)
    // fmt.Println(bufferUrl1)

}

但是现在，我的构建甚至都没有成功。我只对这条消息表示欢迎：

.\hello.go:69: cannot use bufferUrl1 (type [40000]string) as type string in argument to stringInSlice
.\hello.go:69: cannot use buffer (type [2000]string) as type []string in argument to stringInSlice
