报错:
Failed to execute ‘createObjectURL’ on ‘URL’: Overload resolution failed.

主要是因为 Chrome 更新后不支持这种用法(其他主流浏览器也不支持),需要改为:

// 增加type 配置,设置下载资源的类型
 link.href = window.URL.createObjectURL(new Blob([blob],{type: 'application/zip'}));

完整代码
Vue 二进制流下载文件参考代码

* 下载文件,需要为二进制文件流 * @param {*} blob 文件流 * @param {*} fileName 文件名称 * @param {*} suffix 后缀 * @param {*} type blob类型 fileUtil.downloadFile = (blob, fileName = '', suffix = '.xlsx', type) => { fileName += suffix // 该方法支持的浏览器不多(IE10支持),但效率更好 if (window.navigator.msSaveOrOpenBlob) { navigator.msSaveOrOpenBlob(blob, fileName) } else { const link = document.createElement('a') // link.href = window.URL.createObjectURL(blob) 主流浏览器已不支持此种方式,通过下面代码处理 link.href = window.URL.createObjectURL(new Blob([blob]{type})) link.download = fileName link.click() window.URL.revokeObjectURL(link.href) swagger测试导出报URL.createObjectURL: Argument 1 is not valid for any of the 1-argument overloads. 1. 报错信息 Uncaught (in promise) TypeError: Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided. window.URL.createObjectURL()在IE10, IE11中报“Error: 拒绝访问的”错误. 解决方式 const pdfData = new Blob([content], { type: ‘text/csv’ }); if (window.navigator && window.navigator.msSaveOrOpenBlob) { window.navigator.msSaveOrOpenBlob(pdfData , file_name); 转自:https://blog.csdn.net/Miss_Liang/article/details/85781396 window.URL.createObjectURL(mediaStream) 出现 typeError 错误的原因是 浏览器正在取消对 mediaStream 类型的支持 解决方案: video.srcObject = mediaStream 代码示例...
