我的 ionic 函数之一出现以下错误：

 Error: [$interpolate:interr] Can't interpolate: {{detailMl.file}}
Error: [$sce:insecurl] Blocked loading resource from url not allowed by $sceDelegate policy.  URL: http://192.168.1.105/sonschool/upload/mm_learning/44ec994b4e8892932d979ac93d045fa0.pdf

请帮帮我..
这段代码有效：

$scope.pdfURL = "school.pdf";

然后我用以下代码更改此代码：

var baseUrl = 'http://192.168.1.105/sonschool/api/'; $http.get(baseUrl+'ambilDetailML/?id='+$stateParams.mlId).success(function(dataML) { //console.log(dataML); $scope.pdfURL = dataML.url_pdf; });

关于可能导致错误的任何想法？

为了能够使用外部资源，您必须将它们列入白名单（这就是本地“school.pdf”文件有效而使用 IP 的文件无效的原因）。可以在此处找到有关如何执行此操作的教程。

但是，很快，您应该安装cordova-plugin-whitelist插件并将以下内容添加到您的www/index.html文件中其他元标记的正下方：

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
