当RN https 遇见Android 和 http 遇见IOS 的处理方法

1 IOS 的请求和加载http的处理

注意：
NSAppTransportSecurity

NSAllowsArbitraryLoads

2.当android 遇到https;

由于RectNative 底层请求网络用的OKhttp默认是无法加载https 的请求
处理稍微复杂：需要修改Android 原生代码处理所有https的协议

package com.wx_hcx_rn;

import android.app.Application;

import com.facebook.react.ReactApplication;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.modules.network.OkHttpClientProvider;
import com.facebook.react.shell.MainReactPackage;
import com.facebook.soloader.SoLoader;

import java.util.Arrays;
import java.util.List;

public class MainApplication extends Application implements ReactApplication {

  private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

    @Override
    protected List getPackages() {
      return Arrays.asList(
          new MainReactPackage()
      );
    }

    @Override
    protected String getJSMainModuleName() {
      return "index";
    }
  };

  @Override
  public ReactNativeHost getReactNativeHost() {
    return mReactNativeHost;
  }

  @Override
  public void onCreate() {
    super.onCreate();
//修改okhttpclient
    OkHttpClientProvider.replaceOkHttpClient(HttpsOkHttpClient.initCustomOkHttpClient());
    SoLoader.init(this, /* native exopackage */ false);
  }
}

下面是自定义的okhttpclient
