uniapp项目打包成APP后 提供jsbridge给webview调用

可以。web-view通过postMessage向app发送消息。app通过evalJS向web-view注入回调.

web-view中：

uni.webView.postMessage({  
    data: {  
        type: '__JSBridge',  
        action: 'getCamera',  
        callBackFn: 'cameraCallBack'  
    }  
})  

window.cameraCallBack = function(e){  
    console.log('ecameraCallBack boredape:>>>>>>>>>>>> todo_tmFilename-:todo_tmLineNumber', e);  
}  

APP：

<web-view src="http://192.168.0.111:8080/#/" @onPostMessage="handlePostMsg" @message="handlePostMsg"></web-view>

handlePostMsg(bridgeData){  
    const {  
        detail: { data: [{ action, type, params, callBackFn }] },  
    } = bridgeData;  
if (type === '__JSBridge') {  
    const pages = getCurrentPages();   
    const childrenPage = pages[pages.length - 1].$getAppWebview().children()[0];  

    uni.chooseImage({  
    success({tempFilePaths}) {  
        // 向webview注入回调  
        page.evalJS(`${callBackFn}('${tempFilePaths}')`)  
    }  
    })  
}  
}
