我有以下 http 處理程序的代碼，它在隨后的請求中從 Amazon S3 下載原始圖像并將其轉(zhuǎn)換為所需的縱橫比并將其保存回 s3。這段代碼會泄漏內(nèi)存，一段時間后它會崩潰。我從我這邊處理了所有事情，并對代碼進行了分析。但是，還是想不通問題。如果有人能在這里弄清楚，將不勝感激。僅供參考，我正在使用該go version go1.5.3 linux/amd64版本。分析輸出：3259.27kB of 3302.42kB total (98.69%)Dropped 258 nodes (cum <= 16.51kB)Showing top 30 nodes out of 91 (cum >= 27.76kB) flat flat% sum% cum cum% 1552.59kB 47.01% 47.01% 1552.59kB 47.01% bytes.makeSlice 584kB 17.68% 64.70% 584kB 17.68% imagick._Cfunc_GoBytes 257.38kB 7.79% 72.49% 257.38kB 7.79% encoding/pem.Decode 168.11kB 5.09% 77.58% 168.11kB 5.09% crypto/tls.(*block).reserve 165.09kB 5.00% 82.58% 389.49kB 11.79% crypto/x509.parseCertificate 105.32kB 3.19% 85.77% 105.32kB 3.19% reflect.unsafe_NewArray 83.64kB 2.53% 88.30% 83.64kB 2.53% math/big.nat.make 75.55kB 2.29% 90.59% 75.55kB 2.29% net/http.(*Transport).dialConn 64.02kB 1.94% 92.53% 64.02kB 1.94% regexp.(*bitState).reset 43.77kB 1.33% 93.85% 43.77kB 1.33% crypto/x509.(*CertPool).AddCert 40.44kB 1.22% 95.08% 40.44kB 1.22% crypto/x509/pkix.(*Name).FillFromRDNSequence 40.16kB 1.22% 96.29% 40.16kB 1.22% encoding/asn1.parsePrintableString 24.07kB 0.73% 97.02% 24.07kB 0.73% net/http.newBufioWriterSize 18.98kB 0.57% 97.60% 18.98kB 0.57% net/http.newBufioReader 16.14kB 0.49% 98.09% 64.77kB 1.96% crypto/tls.(*Conn).readHandshake 12.01kB 0.36% 98.45% 237.09kB 7.18% encoding/asn1.parseField 8.01kB 0.24% 98.69% 91.65kB 2.78% crypto/x509.parsePublicKey 0 0% 98.69% 112.33kB 3.40% bufio.(*Reader).Read 0 0% 98.69% 80.32kB 2.43% bufio.(*Reader).fill 0 0% 98.69% 27.76kB 0.84% bufio.(*Writer).ReadFrom 0 0% 98.69% 27.76kB 0.84% bufio.(*Writer).flush 0 0% 98.69% 1648.33kB 49.91% bytes.(*Buffer).ReadFrom

你正在泄漏一根魔杖。
在這里，您分配一個新魔杖并將其推遲銷毀：
tx := imagick.NewMagickWand() defer tx.Destroy()
但是再往下，在“if”塊中，您將其替換為從調(diào)用返回的魔杖TransformImage()：
tx = mw.TransformImage("", size)
tx.SetImageGravity(imagick.GRAVITY_CENTER)如果您完全擺脫了新魔杖的第一次分配，只需確保Destroy()從 返回的新魔杖TransformImage()，泄漏就會消失。
