The hope is to quickly parse a very large number of similar URLs (only one &#39;id&#39; element differs from one to the next) and dump the response body into a channel that will later be queried by the main function and used to build a text file.
Inside the `getpageCanal()` function, the body seems to be ok, but after that, I don&#39;t understand why the channel doesn&#39;t properly load the body string.
```golang
package main
import (
	&quot;fmt&quot;
	&quot;io/ioutil&quot;
	&quot;net/http&quot;
	&quot;os&quot;
)
func main() {
	initial := &quot;https://www1.medion.de/downloads/index.pl?op=detail&amp;id=&quot;
	ending := &quot;&amp;type=treiber&amp;lang=uk&quot;
	links := []string{}
	os.Remove(&quot;dump.txt&quot;)
	dumpFile, _ := os.Create(&quot;dump.txt&quot;)
	c := make(chan string)
	for i := 16000; i &lt; 16004; i++ {
		links = append(links, initial+fmt.Sprint(i)+ending)
	}
	fmt.Println(links[0])
	for _, link := range links {
        //the hope is to make this a go routine, but first I need to just make it work
		getpageCanal(c, link)
	}
	for el := range c {
		fmt.Println(el)
		n, err := dumpFile.WriteString(el)
		if err != nil {
			fmt.Println(err)
		}
		if n == 0 {
			fmt.Println(&quot; nothing written in main&quot;)
		}
	}
}
func getpageCanal(canal chan string, url string) {
	defer close(canal)
	page, err := http.Get(url)
	if err != nil {
		fmt.Println(&quot;you done fucked up, boy&quot;)
	}
	content, er2 := ioutil.ReadAll(page.Body)
	//fmt.Println(content)
	if er2 != nil {
		fmt.Println(er2)
	}
	canal &lt;- string(content)

根据第一个评论的指示（在每次调用后不关闭通道，并将对工作函数的调用设置为goroutine），我现在将为您提供一个可工作的版本：
```go
package main
import (
	"fmt"
	"io/ioutil"
	"net/http"
	"os"
)
func main() {
	initial := "https://www1.medion.de/downloads/index.pl?op=detail&id="
	ending := "&type=treiber&lang=uk"
	links := []string{}
	os.Remove("dump.txt")
	dumpFile, _ := os.Create("dump.txt")
	c := make(chan string)
	for i := 16000; i < 16004; i++ {
		links = append(links, initial+fmt.Sprint(i)+ending)
	}
	fmt.Println(links[0])
	for _, link := range links {
		go getpageCanal(c, link)
	}
	for el := range c {
		fmt.Println(el)
		n, err := dumpFile.WriteString(el)
		if err != nil {
			fmt.Println(err)
		}
		if n == 0 {
			fmt.Println(" nothing written in main")
		}
	}
}
func getpageCanal(canal chan string, url string) {
	//defer close(canal)
	page, err := http.Get(url)
	if err != nil {
		fmt.Println("you done fucked up, boy")
	}
	content, er2 := ioutil.ReadAll(page.Body)
	//fmt.Println(content)
	if er2 != nil {
		fmt.Println(er2)
	}
	canal <- string(content)
}
