Question

我是Angular2的新手，并使用ng2-uploader模块在Angular2中实现文件上传。上传工作正常，但我在控制台上遇到错误。任何人都可以帮我理清这个

文件上传后，我收到如下控制台错误：

EXCEPTION: _this.files.filter is not a function
 at ng-file-select.ts:42
at SafeSubscriber.schedulerFn [as _next] (async.js:105)
at SafeSubscriber.__tryOrUnsub (Subscriber.js:238)

at ZoneDelegate.invokeTask (zone.js:366)
at Zone.runTask (zone.js:166)
at XMLHttpRequest.ZoneTask.invoke (zone.js:420)

我也面临着xhr请求的问题 Xhr请求为单个文件上传启动两次

请建议我解决问题的任何解决方案

Answer 1

我也在使用ng2-uploader上传文件。它显示了我同样的问题。但如果我没有返回任何内容，那么它会向服务器端点击两次并且相同的文件上传两次。

_this.files.filter不是函数ng2-uploader angular2文件上传
