react-native-network-info

本项目基于 react-native-network-info 开发。

该第三方库的仓库已迁移至 Gitcode，且支持直接从 npm 下载，新的包名为：@react-native-ohos/react-native-network-info。 版本所属关系如下：

1. 安装与使用

进入到工程目录并输入以下命令：

npm

npm install @react-native-ohos/react-native-network-info

yarn

yarn add @react-native-ohos/react-native-network-info

下面的代码展示了这个库的基本使用场景：

import React, {useState} from 'react';
import {
  View,
  Text,
  StyleSheet,
  ScrollView,
  TouchableOpacity,
} from 'react-native';
import {NetworkInfo} from 'react-native-network-info';

interface NetworkInfoState {
  ipAddress: string | null;
  ipv4Address: string | null;
  broadcast: string | null;
  ssid: string | null;
  bssid: string | null;
  subnet: string | null;
  defaultGateway: string | null;
  frequency: number | null;
}

export function NetworkInfoDemo() {
  const [info, setInfo] = useState<NetworkInfoState>({
    ipAddress: '',
    ipv4Address: '',
    broadcast: '',
    ssid: '',
    bssid: '',
    subnet: '',
    defaultGateway: '',
    frequency: 0,
  });

  return (
    <ScrollView style={styles.container}>
      <View style={styles.infoContainer}>
        <TouchableOpacity
          onPress={async () => {
            const value = await NetworkInfo.getIPAddress();
            setInfo({...info, ipAddress: value});
          }}>
          <Text style={styles.button}>ipAddress</Text>
        </TouchableOpacity>
        <Text style={styles.infoText}>{`${info.ipAddress}`}</Text>
      </View>

      <View style={styles.infoContainer}>
        <TouchableOpacity
          onPress={async () => {
            const value = await NetworkInfo.getIPV4Address();
            setInfo({...info, ipv4Address: value});
          }}>
          <Text style={styles.button}>ipv4Address</Text>
        </TouchableOpacity>
        <Text style={styles.infoText}>{`${info.ipv4Address}`}</Text>
      </View>

      <View style={styles.infoContainer}>
        <TouchableOpacity
          onPress={async () => {
            const value = await NetworkInfo.getBroadcast();
            setInfo({...info, broadcast: value});
          }}>
          <Text style={styles.button}>broadcast</Text>
        </TouchableOpacity>
        <Text style={styles.infoText}>{`${info.broadcast}`}</Text>
      </View>

      <View style={styles.infoContainer}>
        <TouchableOpacity
          onPress={async () => {
            const value = await NetworkInfo.getSSID();
            setInfo({...info, ssid: value});
          }}>
          <Text style={styles.button}>ssid</Text>
        </TouchableOpacity>
        <Text style={styles.infoText}>{`${info.ssid}`}</Text>
      </View>
    </ScrollView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 20,
  },
  infoContainer: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    alignItems: 'center',
    marginBottom: 10,
  },
  infoText: {
    fontSize: 16,
  },
  button: {
    paddingVertical: 6,
    paddingHorizontal: 12,
    backgroundColor: 'hsl(193, 95%, 68%)',
    borderWidth: 2,
    borderColor: 'hsl(193, 95%, 30%)',
    borderRadius: 4,
  },
});

2. Link

使用AutoLink的工程需要根据该文档配置，Autolink框架指导文档：https://gitcode.com/openharmony-sig/ohos_react_native/blob/master/docs/zh-cn/Autolinking.md

如您使用的版本支持 Autolink，并且工程已接入 Autolink，可跳过ManualLink配置。

{
  "overrides": {
    "@rnoh/react-native-openharmony" : "./react_native_openharmony"
  }
}

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-ohos/react-native-network-info": "file:../../node_modules/@react-native-ohos/react-native-network-info/harmony/rn_network_info.har"
  }

cd entry
ohpm install

+ set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")

# RNOH_BEGIN: manual_package_linking_1
+ add_subdirectory("${OH_MODULES}/@react-native-ohos/react-native-network-info/src/main/cpp" ./rn_network_info)
# RNOH_END: manual_package_linking_1

# RNOH_BEGIN: manual_package_linking_2
+ target_link_libraries(rnoh_app PUBLIC rnoh_network_info)
# RNOH_END: manual_package_linking_2

#include "RNOH/PackageProvider.h"
#include "generated/RNOHGeneratedPackage.h"
+ #include "NetworkInfoPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
      std::make_shared<RNOHGeneratedPackage>(ctx),
+     std::make_shared<NetworkInfoPackage>(ctx),
    };
}

  ...
+  import { RNNetworkInfoPackage } from '@react-native-ohos/react-native-network-info/ts';
export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new RNNetworkInfoPackage(ctx)
  ];
}

2.5. 运行

点击右上角的 sync 按钮

或者在命令行终端执行：

cd entry
ohpm install

然后编译、运行即可。

3. 约束与限制

3.1. 兼容性

本文档内容基于以下版本验证通过：

1. RNOH: 0.72.96; SDK: HarmonyOS 6.0.0 Release SDK; IDE: DevEco Studio 6.0.0.858; ROM: 6.0.0.112;
2. RNOH: 0.72.33; SDK: HarmonyOS NEXT B1; IDE: DevEco Studio: 5.0.3.900; ROM: Next.0.0.71;
3. RNOH: 0.77.18; SDK: HarmonyOS 6.0.0 Release SDK; IDE: DevEco Studio 6.0.0.858; ROM: 6.0.0.112;
4. RNOH: 0.82.1; SDK: HarmonyOS 6.0.0 Release SDK; IDE: DevEco Studio 6.0.0.858; ROM: 6.0.0.112;

3.2. 权限要求

在 entry 目录下的 module.json5 中添加wifi和网络信息权限

打开entry/src/main/module.json5，添加：

...
"requestPermissions": [
    {
    "name" : "ohos.permission.GET_WIFI_INFO"
    },
    {
    "name": "ohos.permission.GET_NETWORK_INFO"
    }
]
