Question

我正在尝试将github.com/willnorris/imageproxy/集成到现有服务器上，并将图像投放到＆＃34; / proxy /＆＃34;路径。我有：

            String protocol = Protocol.HTTP.toString();
            String host = "somproxy.foo";
            int port = 8888;
            String path = null;
            String auth = null;
            String fragment = null;
            URI uri = new URI(protocol, auth, host, port, path, null, fragment);
            ProxyConfiguration.Builder builder = ProxyConfiguration.builder().endpoint(uri);
            ProxyConfiguration proxyConfiguration = builder.build();

            ApacheSdkHttpClientFactory
                apacheSdkHttpClientFactory =
                ApacheSdkHttpClientFactory.builder().proxyConfiguration(proxyConfiguration).build();

            this.s3Client = S3Client.builder()
                .region(region)
                .httpConfiguration(ClientHttpConfiguration.builder()
                    .httpClientFactory(apacheSdkHttpClientFactory)
                    .build())
                .credentialsProvider(StaticCredentialsProvider.create(awsCredentials))
                .build();

            SdkAsyncHttpClientFactory sdkAsyncHttpClientFactory = null;
            SdkAsyncHttpClient sdkHttpClient = null;

当我尝试调整图像大小时，第一个数字似乎被截止： package main import ( "log" "net/http" "github.com/gorilla/mux" "willnorris.com/go/imageproxy" ) func main() { p := imageproxy.NewProxy(nil, nil) router := mux.NewRouter() router.NewRoute().Name("proxy").Methods("GET").PathPrefix("/proxy/").Handler(http.StripPrefix("/proxy/", p)) server := &http.Server{ Addr: ":8000", Handler: router, } //server.Handler = p log.Printf("Listening at %v", server.Addr) log.Fatal(server.ListenAndServe()) }

返回50x50图像而不是250x250图像。

可以访问250x250的图像 http://127.0.0.1:8000/proxy/250x,/https:/octodex.github.com/images/codercat.jpg

取消注释http://127.0.0.1:8000/proxy/2250x,/https:/octodex.github.com/images/codercat.jpg作品和图片会按预期调整大小。

在调用图像代理处理程序之前，使用http.StripPrefix从请求路径中删除“/ proxy”。请注意，StripPrefix的第一个参数没有尾随/。

router.NewRoute().Name("proxy").Methods("GET").PathPrefix("/proxy/").Handler(http.StripPrefix("/proxy", p))

无法在图像代理上调整图像大小
