推荐答案

每当您读取文本时，它都会对底层的二进制0/1字符应用某种编码(ASCII，Unicode等)以进行读取.这就是导致特殊字符的原因.因此，您需要以流的形式上载/下载文件(不确定AngularJS如何使用它的引用).请检查 AngularJS:如何实现简单用分段形式上传文件?

Whenever you do a read as text, it applies a certain encoding (ASCII, Unicode etc) to the underlying binary 0/1 characters to do the reading. This is what causing the special characters. Hence you need to upload/download files as stream (not sure of AngularJS reference of how to do it). Please check this AngularJS: how to implement a simple file upload with multipart form?
