package main import ( "compress/gzip" "fmt" "io" "io/ioutil" "net/http" "reflect" "github.com/mozillazg/request" ) func test1(url string) (bt []byte, err error) { testResp, err := http.Get(url) if err != nil { return } bt, err = ioutil.ReadAll(testResp.Body) return } func test2(url string) (bt []byte, err error) { c := new(http.Client) req := request.NewRequest(c) resp, err := req.Get(url) if err != nil { return } bt, err = ioutil.ReadAll(resp.Body) return } func test3(url string) (bt []byte, err error) { c := new(http.Client) req := request.NewRequest(c) resp, err := req.Get(url) if err != nil { return } var reader io.ReadCloser if resp.Header.Get("Content-Encoding") == "gzip" { reader, err = gzip.NewReader(resp.Body) if err != nil { return } } else { reader = resp.Body } bt, err = ioutil.ReadAll(reader) return } func main() { urls := [...]string{"https://www.baidu.com", "https://httpbin.org/status/418"} for i := range urls { url := urls[i] fmt.Println("\n----------\n") fmt.Println("url =", url) b1, _ := test1(url) b2, _ := test2(url) fmt.Println(b1) fmt.Println(b2) fmt.Println(reflect.DeepEqual(b1, b2)) fmt.Println("\n----------\n") b3, _ := test3(url) fmt.Println(b3) fmt.Println(reflect.DeepEqual(b1, b3)) } } 乱码产生的原因是因为网站使用了gzip进行压缩，而request库没有对其进行相应的解压，手动解压下就解决了
