Question

我正在为我的公司开发一个应用，需要在 https 网址上发布一些数据。

我正在使用复古，但我收到以下错误SSLHandshakeException: Connection closed by peer

这是我正在使用的代码

服务生成器

public class ServiceGenerator {

    public static final String API_BASE_URL = "https://website.com/api/";

    private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

    private static Retrofit.Builder builder =
            new Retrofit.Builder()
                    .baseUrl(API_BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create());

    public static <S> S createService(Class<S> serviceClass) {
        Retrofit retrofit = builder.client(httpClient.build()).build();
        return retrofit.create(serviceClass);
    }
}

服务

public interface ITrackTraceService {

    @Headers("Content-Type: application/json")
    @POST("beepbeep/postdata")
    Call<String> PostLocation(@Body DataInput input);

}

自称

Location location = getLocation();

        TrackTraceService.ITrackTraceService srv = ServiceGenerator.createService(TrackTraceService.ITrackTraceService.class);

        DataInput i = new DataInput();
        i.Eta = new Date();
        i.Reference = "123456789";
        i.Status = "Tracking";
        i.Device = new Device();
        i.Reading = new Reading();
        i.Reading.Time = new Date();
        i.Reading.Location = new DeviceLocation();
        i.Reading.Location.Accuracy = location.getAccuracy();
        i.Reading.Location.Altitude = (float) location.getAltitude();
        i.Reading.Location.Latitude = (float) location.getLatitude();
        i.Reading.Location.Longitude = (float) location.getLongitude();
        i.Reading.Location.Speed = (float) location.getSpeed();
        i.Reading.Location.Time = new Date(location.getTime());
        Call<String> call = srv.PostLocation(i);

        call.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response) {

                if (response.isSuccessful()) {
                    Log.d("Service", "onResponse");
                } else {
                    // error response, no access to resource?
                }
            }

            @Override
            public void onFailure(Call<String> call, Throwable throwable) {
                StringWriter sw = new StringWriter();
                PrintWriter pw = new PrintWriter(sw);
                throwable.printStackTrace(pw);
                Log.d("Service", call.request().toString());
                Log.e("Service", "onFailure", throwable);
                Log.d("Error", throwable.getMessage());
            }
        });
    }

我遇到了同样的问题

但对于我来说，问题是我的device是connected到wifi的地方，但是wifi路由器是not具有internet的连接，然后exception被抛出了

如果您在没有有效证书的服务器上测试应用程序，则可能会发生此错误。

最好的方法是获得授权的SSL证书。

如果是测试服务器，则尝试在项目中添加此代码，并在调用Web服务之前调用它 PS：在将您的应用上传到PlayStore之前，应删除此代码。您应该使用具有授权SSL证书的服务器。

private static void disableSSLCertificateChecking() {

    System.out.println("INSIDE DISABLE SSLC");
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        @Override
        public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }

        @Override
        public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
            // Not implemented
        }
    } };

    try {
        SSLContext sc = SSLContext.getInstance("TLS");

        sc.init(null, trustAllCerts, new java.security.SecureRandom());

        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

基本上，此代码忽略从服务器收到的任何证书（有效/无效）。

我已经读过的另一个答案（一段时间后）说明改变okhttp的版本（IDK，如果这是你的情况，但是那个人也使用了改装）可以防止这个错误。
