TypeError:在上的网络请求在华为Y6的调试模式下失败

Question

当我在一个真正的设备上启动我的应用时，华为的Y6和Android在中使用，获取请求不起作用。我得到TypeError:网络请求失败。同时，如果我在android仿真器上启动我的应用程序，则fetch可以工作。如果我生成一个APK文件，并在我的华为上安装它之后，fetch也能正常工作。我想问题可能出在本地。如果有人犯了同样的错误，请告诉我！

ServiceApi类：

class TeamApiService {
  createTeam = async () => {
    const response = await fetch(AppConstants.CREATE_TEAM, {
      method: 'POST',
      headers: {},
    });
    const { status } = response;

    if (status === STATUS_CODES.SUCCESSFUL) {
      const result = await response.json();

      return result;
    }

    return this.apiErrorHandler(status, 'createTeam');
  };
}

export default new TeamApiService();

只需在main/java文件夹下创建一个新的类FetchApiClientFactory

package com.xxxxxxx;

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

import java.security.cert.CertificateException;
import java.util.ArrayList;

import java.util.List;
import android.util.Log;

import java.util.concurrent.TimeUnit;

import javax.net.ssl.HostnameVerifier;
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.CipherSuite;
import okhttp3.ConnectionSpec;
import okhttp3.OkHttpClient;
import okhttp3.TlsVersion;

import static android.content.ContentValues.TAG;


public class FetchApiClientFactory implements OkHttpClientFactory {
    private static final String TAG = "OkHttpClientFactory";

    @Override
    public OkHttpClient createNewNetworkModuleClient() {
        try {
// Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[]{
                    new X509TrustManager() {

                        @Override
                        public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                            return new java.security.cert.X509Certificate[]{};
                        }
                    }
            };

            // Install the all-trusting trust manager
            final SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
            // Create an ssl socket factory with our all-trusting manager
            final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();


            OkHttpClient.Builder builder = new OkHttpClient.Builder()
                    .connectTimeout(0, TimeUnit.MILLISECONDS).readTimeout(0, TimeUnit.MILLISECONDS)
                    .writeTimeout(0, TimeUnit.MILLISECONDS).cookieJar(new ReactCookieJarContainer());
            builder.sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0]);
            builder.hostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            });

            OkHttpClient okHttpClient = builder.build();
            return okHttpClient;
        } catch (Exception e) {
            Log.e(TAG, e.getMessage());
            throw new RuntimeException(e);
        }
    }
}

并在MainApplication.java中添加这一行

 @Override
  public void onCreate() {
    super.onCreate();
    
    OkHttpClientProvider.setOkHttpClientFactory(new FetchApiClientFactory()); // this line
  }
