react-native-http-bridge

本项目基于 react-native-http-bridge 开发。

请到三方库的 Releases 发布地址查看配套的版本信息：@react-native-ohos/react-native-http-bridge Releases。对于未发布到npm的旧版本，请参考安装指南安装tgz包。

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-http-bridge

yarn

yarn add @react-native-ohos/react-native-http-bridge

下面的代码展示了这个库的基本使用场景：

import React, { useState ,useEffect } from "react";
import { ScrollView, Text, Button, View, StyleSheet } from 'react-native';

var httpBridge = require('react-native-http-bridge');

const HttpBridgeDemo = () => {
  const [getRequestResult, setGetRequestResult] = useState('');
  const [postRequestResult, setPostRequestResult] = useState('');
  const GetMothedExample = () => {
    fetch('http://127.0.0.1:8888/student/getStuInfo?value=GET', {
      method: 'GET',
      headers: {
        'Content-Type': 'application/json',
      }
    })
  }

  const PostMothedExample = () => {
    fetch('http://127.0.0.1:8888/student/postStuInfo', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        firstParam: 'yourValue',
        secondParam: 'yourOtherValue',
      })
    })
  }
  useEffect(() => {
    httpBridge.start(8888, 'http_service', (request: any) => {
      switch (request.type) {
        case 'GET':
          setGetRequestResult('requestId: ' + request.requestId + '\ntype: ' +
            request.type + '\nurl: ' + request.url + '\npostData: ' + request.postData);
          break;
        case 'POST':
          setPostRequestResult('requestId: ' + request.requestId + '\ntype: ' +
            request.type + '\nurl: ' + request.url + '\npostData: ' + request.postData);
          break;
      }
      if (request.type === "GET" && request.url.split("/")[1] === "user") {
        httpBridge.respond(request.requestId, 200, "application/json", "{\"message\": \"OK\"}");
      } else {
        httpBridge.respond(request.requestId, 400, "application/json", "{\"message\": \"Bad Request\"}");
      }
    });
    return () => {
      httpBridge.stop();
    }
  }, []);

  return (
  	<ScrollView>
      <View>
      <Text style={styles.text}>httpBridgeExample Port : 8888</Text>
        <View>
          <Text style={styles.text}>Method：GET</Text>
          <Button
            title="GET"
            color="#9a73ef"
            onPress={GetMothedExample}
          />
          <Text style={styles.result} allowFontScaling>{getRequestResult}</Text>
        </View>

        <View>
          <Text style={styles.text}>Method：POST</Text>
          <Button
            title="POST"
            color="#9a73ef"
            onPress={PostMothedExample}
          />
          <Text style={styles.result} allowFontScaling>{postRequestResult}</Text>
        </View>
      </View>
    </ScrollView>
 )
};

const styles = StyleSheet.create({
  text: {
    fontSize: 18,
    marginBottom: 10,
    color: 'red',
  },
  result: {
    marginTop: 10,
    fontSize: 18,
    marginBottom: 10,
    color: 'white',
  }
});
export default HttpBridgeDemo;

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。

2.5. 运行

点击右上角的 sync 按钮

或者在终端执行：

cd entry
ohpm install

然后编译、运行即可。

3. 约束与限制

3.1. 兼容性

在以下版本验证通过：

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 6.0.1 Release SDK; IDE: DevEco Studio 6.0.1 Release; ROM:6.0.0.130 SP8;

3.2. 权限要求

3.2.1. 在 entry 目录下的module.json5中添加权限

打开 entry/src/main/module.json5，添加：

...
"requestPermissions": [
+  {
+    "name": "ohos.permission.KEEP_BACKGROUND_RUNNING",
+    "reason": "$string:app_name",
+    "usedScene": {
+      "abilities": [
+        "FormAbility"
+      ],
+      "when": "always"
+    }
+  },
]

4. API

4.1. start

start(port:number, serviceName:string, callback): void;

4.2. respond

respond(requestId:string, code:number, type:string, body:string): void;
