带有额外字段的 FormData 多文件上传

Question

我正在以这种方式上传和附加多个文件：

Component.For<A>().ImplementedBy<SomeAImpl>().DependsOn((_, d) d['SomeKey'] = 'SomeTriggerValue')

如何才能让我同时发送 this.selected_images = [ {file: File, file_name: 'some_file_name', file_ext: 'some_file_ext'}, {file: File, file_name: 'some_file_name', file_ext: 'some_file_ext'}, {file: File, file_name: 'some_file_name', file_ext: 'some_file_ext'}, {file: File, file_name: 'some_file_name', file_ext: 'some_file_ext'}, ] const f = new FormData(); for (let i = 0; i < this.selected_images.length; i++) { let file = this.selected_images[i].file; f.append('files[' + i + ']', file); } 和 file_name 键以及文件？
