Retrofit不支持CLEARTEXT通信

hub*_*ert 23 ssl android http retrofit

我正在尝试使用Retrofit连接到android上的https服务器.这是我的OkHttpClient

@Provides
public OkHttpClient provideContactClient(){
  HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
  ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
      .tlsVersions(TlsVersion.TLS_1_2)
      .cipherSuites(CipherSuite.TLS_RSA_WITH_DES_CBC_SHA,
          CipherSuite.TLS_RSA_WITH_AES_128_GCM_SHA256,
          CipherSuite.TLS_DHE_RSA_WITH_AES_128_GCM_SHA256)
      .build();
  interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
  SSLSocketFactory sslSocketFactory = null;
  try {
    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, null, null);
    sslSocketFactory = sslContext.getSocketFactory();
  }catch (GeneralSecurityException e){
    e.printStackTrace();
  }
  return new OkHttpClient.Builder()
      .addInterceptor(interceptor)
      .connectionSpecs(Collections.singletonList(spec))
      .sslSocketFactory(sslSocketFactory)
      .authenticator(new Authenticator() {
        @Override
        public Request authenticate(Route route, Response response) throws IOException {
          if(responseCount(response) >= 5){
            return null;
          }
          String credential = Credentials.basic("user", "pass");
          return response.request().newBuilder().header("Authorization", credential).build();
        }
      })
      .build();
}

但是我一直都是CLEARTEXT communication not supported:例外

在调试RealConnection类时,我注意到route.address()成员没有sslSocketFactory在Bulider中分配它.

根据网络安全配置

本部分中的指南仅适用于针对Android 8.1(API级别27)或更低级别的应用.从Android 9(API级别28)开始,默认情况下禁用明文支持.

创建文件res/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">Your URL(ex: 127.0.0.1)</domain>
    </domain-config>
</network-security-config>

或者您可以直接在清单中设置应用程序.

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="true"
        ...>
        ...
    </application>
</manifest>

CLEARTEXT消息归因于http直接或通过服务器端重定向(例如,以开头https,然后重定向至http)请求的URL 。

对于“未找到证书路径的信任锚”消息而言,您的服务器似乎正在使用某些SSL证书,该证书在任何要测试的Android环境上均不受标准证书之一的支持。例如,也许您的服务器使用的是自签名SSL证书。
