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。
