在Go语言中处理并发网络请求的流量控制问题,可以使用以下方法:
示例代码如下:
package main
import "fmt"
func main() {
maxConcurrency := 10
concurrencyCh := make(chan struct{}, maxConcurrency)
urls := []string{"http://example.com", "http://example.org", "http://example.net"}
for _, url := range urls {
// Acquire channel position
concurrencyCh <- struct{}{}
go func(url string) {
// Process the request
// ...
// Release channel position
<-concurrencyCh
}(url)
}
// Wait for all requests to complete
for i := 0; i < maxConcurrency; i++ {
concurrencyCh <- struct{}{}
}
}
示例代码如下:
package main
import (
"fmt"
"sync"
)
func main() {
var wg sync.WaitGroup
maxConcurrency := 10
urls := []string{"http://example.com", "http://example.org", "http://example.net"}
for _, url := range urls {
// Increment wait group counter
wg.Add(1)
go func(url string) {
defer wg.Done()
// Process the request
// ...
}(url)
}
// Wait for all requests to complete
wg.Wait()
}
使用以上方法可以有效地控制并发网络请求的流量,避免过多的请求导致系统资源耗尽。
