问题描述
我正在尝试让 this 信用卡读卡器处理我的 Angular 应用程序。我按照阅读中的所有步骤操作并获得了许可证密钥，但由于某种原因，我收到以下错误
Error during the initialization of the SDK! DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:4200/BlinkCardWasmSDK.js' Failed to load.
在我的组件中，我根据说明实现了以下方法：
scanCard() {
if ( BlinkCardSDK.isbrowserSupported() ) {
const loadSettings = new BlinkCardSDK.WasmSDKLoadSettings( 'sRwAAAYJbG9jYA==' );
BlinkCardSDK.loadWasmModule( loadSettings ).then
(
( wasmSDK: BlinkCardSDK.WasmSDK ) => {
// The SDK was initialized successfully,save the wasmSDK for future use
BlinkCardSDK.createBlinkCardRecognizer( wasmSDK ).then(recognizer => {
BlinkCardSDK.createRecognizerRunner( wasmSDK,[ recognizer ],true ).then(recognizerRunner => {
const cameraFeed = document.getElementById( 'camera-Feed' ) as HTMLVideoElement;
BlinkIDSDK.VideoRecognizer.createVideoRecognizerFromCameraStream(cameraFeed,recognizerRunner)
.then(videoRecognizer => {
videoRecognizer.recognize().then(processResult => {
if ( processResult !== BlinkIDSDK.RecognizerResultState.Empty ) {
recognizer.getResult().then(recognitionResult => {
console.log( recognitionResult );
});
} else {
console.log( 'Recognition was not successful!' );
}
console.log(processResult);
});
});
});
});
},( error: any ) => {
// Error happened during the initialization of the SDK
console.log( 'Error during the initialization of the SDK!',error );
});
} else {
console.log( 'This browser is not supported by the SDK!' );
}
}
在我的 html 中：
<body>
<div id="screen-initial">
<h1 id="msg">Loading...</h1>
<progress id="load-progress" value="0" max="100"></progress>
</div>
<div id="screen-start" class="hidden">
<a href="#" id="start-scan">Start scan</a>
</div>
<div id="screen-scanning" class="hidden">
<video id="camera-Feed" playsinline></video>
<!-- Recognition events will be drawn here. -->
<canvas id="camera-Feedback"></canvas>
<p id="camera-guides">Point the camera towards Payment cards.</p>
</div>
</body>
我在 /src/assets/BlinkCardWasmSDK.js 中添加了 BlinkCardWasmSDK.js 但它仍然给我错误。我是否缺少参考资料或其他东西？预先感谢您的帮助。
解决方法
问题是 BlinkID 找不到它需要的资源。您需要将其指向架构师、构建、选项以及最后的资产数组中的 angular.json 配置文件 (Angular workspace configuration docs) 中资源所在的位置。
"assets": [
{
"glob": "**/*","input": "node_modules/@microblink/blinkid-in-browser-sdk/resources","output": "/"
}
]
您不需要将 BlinkID 资源移动到您的资产中，而是指向它在 node_modules 中的位置。如果这有帮助，请告诉我。
