本文将带你了解IOS开发入门当RN https 遇见Android 和 http 遇见IOS 的处理方法，希望本文对大家学IOS有所帮助。

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<reactpackage>   getPackages() {

      return Arrays.<reactpackage>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);

  }

}

</reactpackage></reactpackage>

?下面是自定义的okhttpclient

import javax.net.ssl.SSLContext;

import javax.net.ssl.SSLSession;

import javax.net.ssl.SSLSocketFactory;

import javax.net.ssl.TrustManager;

import javax.net.ssl.X509TrustManager;

import okhttp3.OkHttpClient;
