Question

我正在尝试上传大小超过1Mb的文件并抱怨大尺寸。我将大小设置为50 MB，但这似乎没有生效。我究竟做错了什么？请帮忙

 @Component({
        moduleId: module.id,
        //define the element to be selected from the html structure.
        selector: 'NeedAnalysisConsult',
        //location of our template rather than writing inline templates.
        templateUrl: 'need-analysis-consultation.component.html',

    })
    export class NeedAnalysisConsultationComponent implements OnInit {
        model:any={};
        consultationDate: Date;
        organisation: string;
        devCode:String;
        maxFileSize = 50 * 1024 * 1024;


         //declare a property called fileuploader and assign it to an instance of a new fileUploader.
        //pass in the Url to be uploaded to, and pass the itemAlais, which would be the name of the //file input when sending the post request.
        public uploader:FileUploader = new FileUploader({url: URL,isHTML5: true, itemAlias: 'consultation',maxFileSize: this.maxFileSize});
        //This is the default title property created by the angular cli. Its responsible for the app works
        title = 'app works!';

        ngOnInit() {
        //override the onAfterAddingfile property of the uploader so it doesn't authenticate with //credentials.
          this.uploader.onAfterAddingFile = (file)=> { file.withCredentials = false; };
          this.uploader.onBuildItemForm=(item:any,form:any)=>{
                form.append('devCode',this.model.programmeCode);
                form.append('date',this.model.consultationDate);
                form.append('organization',this.model.organisation);

          };
        //overide the onCompleteItem property of the uploader so we are
        //able to deal with the server response.
          this.uploader.onCompleteItem = (item:any, response:any, status:any, headers:any) => {
                console.log("FileUpload:successfully uploaded:", item, status, response);
                if (status==201){

                  alert("FileUpload: successfully");

                }
                else {
                 alert("FileUpload:"+response);

              }

            };

我已经测试了您的方法，并且它在我的服务器上正常上传。检查您的服务器是否配置为接受大于1 MB的文件。为了能够确认来自服务器的错误响应，您可以执行以下回调，就像您在onCompleteItem上所做的那样。

 onSuccessItem(item: FileItem, response: string, status: number, headers:ParsedResponseHeaders): any {
            //this gets triggered only once when first file is uploaded       
     }
    onErrorItem(item: FileItem, response: string, status: number, headers: 
           ParsedResponseHeaders): any {
                let error = JSON.parse(response); //error - server response            
            }

然后您可以订阅它们，如下所示：

this.uploader.onErrorItem = (item, response, status, headers) => this.onErrorItem(item, response, status, headers);
this.uploader.onSuccessItem = (item, response, status, headers) => this.onSuccessItem(item, response, status, headers);

这样，您就可以检查错误是否来自服务器。

Answer 2

只有两件事可能会导致这种情况：

客户端 如果ng2-file-upload maxFileSize 参数小于 1MB

服务器端 如果您在服务器端使用PHP，请在 php.ini

中调整以下参数

post_max_size = 50M ＃表示单个发布请求不应无论文件数量多大，在任何给定时间都超过50MB 已上传。
upload_max_filesize = 50M ＃表示没有单独的文件每个请求超过50MB
max_file_uploads = 10 ＃表示只能上传10个文件在一个请求中

使用Angular 2和Typescript的“ng2-file-upload”，无法上传1MB以上的文件
