改造2无法解析主机[关闭]

Question

此问题是由打字错误或无法再复制的问题引起的。虽然这里可能有类似的问题，但这一问题的解决方式不太可能对未来的读者有所帮助。

在我以前版本的应用程序中，我使用了Apache客户端，所有的东西都工作了，而且仍然工作。但由于性能有所提高，我们决定进行改装。问题是每次我都会遇到“无法解析主机”xxxxxx：没有与主机名关联的地址”。

我把这个放在舱单里了

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

我还忘了什么吗？

这是url：https://www.hbapimanager.azure-api.net/Wallet/CheckNumber

P、 我已经为此挣扎了将近一周

编辑：这是我的改装工厂类：

private static HttpLoggingInterceptor logging = new HttpLoggingInterceptor()
        .setLevel(BuildConfig.DEBUG ? HttpLoggingInterceptor.Level.BODY : HttpLoggingInterceptor.Level.NONE);

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

private static HttpUrl url = new HttpUrl.Builder()
        .scheme("https")
        .host(Constants.Network.HOST)
        .build();

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

public static <T> T createRetrofitService(final Class<T> clazz) {
    Retrofit retrofit = builder.client(httpClient.build()).build();
    return retrofit.create(clazz);
}

这是请求的接口

    @Headers({
        Constants.Network.HEADER_TYPE,
        Constants.Network.HEADER_KEY
})
@POST(Constants.Network.CHECK_NUMBER)
Call<StatusData> postCheckNumber(@Body CheckNumberPoRD checkNumberPoRD);

@Headers({
        Constants.Network.HEADER_TYPE,
        Constants.Network.HEADER_KEY
})
@GET(Constants.Network.CHECK_NUMBER)
Call<CheckNumberGRD> getCheckNumber(
        @Query("PrimaryKey") String primaryKey,
        @Query("RowKey") String rowKey
);

Answer 1

您肯定遇到了这样一个问题：您的基本URL如下所示：

http://blah.com/v1/blah

你的服务看起来像

@GET("/blah/blah/blah")

但你必须让它看起来像这样：

http://blah.com/v1/blah/

你的服务需要看起来像

@GET("blah/blah/blah")

Answer 2

HttpUrl baseUrl = new HttpUrl.Builder()
                .scheme("https")
                .host("www.hbapimanager.azure-api.net")
                .encodedPath("/Wallet/")
                .build();

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(new AdditionalHttpHeadersInterceptor(headersProvider))
                .addInterceptor(httpLoggingInterceptor)
                .build();

ApiService apiService = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .client(okHttpClient)
                .addConverterFactory(MoshiConverterFactory.create(moshi))
                .build()
                .create(ApiService.class);

ApiService。Java语言

@Headers({
        Constants.Network.HEADER_TYPE,
        Constants.Network.HEADER_KEY
})
@GET(Constants.Network.CHECK_NUMBER)
Call<CheckNumberGRD> getCheckNumber(
        @Query("PrimaryKey") String primaryKey,
        @Query("RowKey") String rowKey
);

其中<代码>常数。网络CHECK\u NUMBER是无斜杠的“CheckNumber”

但是，由于https，您可能必须设置自定义ssl套接字工厂。最简单的方法是next：

创建自定义SSL工厂类

public class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory() {
        SSLContext context = null;
        try {
            context = SSLContext.getInstance("TLS");
            context.init(null, null, null);
        } catch (NoSuchAlgorithmException | KeyManagementException e) {
            //TODO check it and fix
            throw new RuntimeException(e);
        }
        internalSSLSocketFactory = context.getSocketFactory();
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
    }

    @Override
    public Socket createSocket(InetAddress host, int port) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    private Socket enableTLSOnSocket(Socket socket) {
        if (socket != null && (socket instanceof SSLSocket)) {
            ((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1.1", "TLSv1.2"});
        }
        return socket;
    }
}

以及您的自定义X509 trust manager类

public class CustomX509TrustManager implements X509TrustManager {

    @SuppressLint("TrustAllX509TrustManager")
    @Override
    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
    }

    @SuppressLint("TrustAllX509TrustManager")
    @Override
    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return new X509Certificate[]{};
    }
}

创建超文本传输协议客户端

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .sslSocketFactory(new CustomX509TrustManager(), new TLSSocketFactory())
                .addInterceptor(new AdditionalHttpHeadersInterceptor(headersProvider))
                .addInterceptor(httpLoggingInterceptor)
                .build();

Answer 3

我的问题是我试图将请求发送到https://www.example.com.然而，没有www.example。服务器主机中的com，但仅为示例。通用域名格式。
