React Native请求Https请求不通怎么解决

在android/app/src/main/java/com/platfrom中添加CustomOkHttpClientFactory.java

package com.platfrom;

import com.facebook.react.modules.network.OkHttpClientFactory;
import com.facebook.react.modules.network.ReactCookieJarContainer;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.security.SecureRandom;
import okhttp3.OkHttpClient;
import java.util.concurrent.TimeUnit;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import javax.net.ssl.KeyManager;

public class CustomOkHttpClientFactory implements OkHttpClientFactory {

  static SSLSocketFactory sslSocketFactory;
  static X509TrustManager trustManager;
  static {
    trustManager = new X509TrustManager() {
      public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
      }

      public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
      }

      public X509Certificate[] getAcceptedIssuers() {
        return new X509Certificate[0];
      }
    };
    TrustManager[] trustAllCerts = new TrustManager[] { trustManager };

    try {
      SSLContext sslContext = SSLContext.getInstance("TLS");
      sslContext.init((KeyManager[]) null, trustAllCerts, new SecureRandom());
      sslSocketFactory = sslContext.getSocketFactory();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

  @Override
  public OkHttpClient createNewNetworkModuleClient() {
    OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder()
        .connectTimeout(0, TimeUnit.MILLISECONDS)
        .readTimeout(0, TimeUnit.MILLISECONDS)
        .writeTimeout(0, TimeUnit.MILLISECONDS)
        .cookieJar(new ReactCookieJarContainer());
    clientBuilder
        // .sslSocketFactory(sslSocketFactory)（android10及以下）
        .sslSocketFactory(sslSocketFactory, trustManager)
        .hostnameVerifier(new HostnameVerifier() {
          @Override
          public boolean verify(String s, SSLSession sslSession) {
            // 忽略所有的HTTPS认证，直接返回了true
            return true;
          }
        });
    return clientBuilder.build();
  }

}

在MainApplication.java文件中加入

import com.facebook.react.modules.network.OkHttpClientProvider;

OkHttpClientProvider.setOkHttpClientFactory(new CustomOkHttpClientFactory());

新建一个文件夹facebook.react.modules.network，在创建一个NetworkingModuleCreateUtil.java文件

package com.facebook.react.modules.network;

import com.facebook.react.bridge.ReactApplicationContext;

import okhttp3.OkHttpClient;

public class NetworkingModuleCreateUtil {
  public static NetworkingModule create(ReactApplicationContext reactApplicationContext) {
    // 可以在这里对OkHttpClient添加自己的设置，例如添加ssl的自签名证书
    OkHttpClient okHttpClient = OkHttpClientProvider.getOkHttpClient();
    return new NetworkingModule(reactApplicationContext, null, okHttpClient);
  }
}
