在angular 2项目中上传图像的位置? [英] Where to upload image in angular 2 project?

问题描述

我有一个可以上传图片的应用.一切正常，我没有上传本身的问题......但是我遇到了问题，因为一旦我将图像和存储上传到服务器中，angular-clie 就会重新加载页面.

I have an app that can upload images. Everything is working fine, I;m not having issues with the upload itself... But I have issues because as soon as I upload the image and storage in the server, the angular-clie reload the page.

起初，我将图片上传到/src/assets然后我发现 angular-clie 正在刷新页面，因为它检测到它正在列出的文件夹中的一些新内容.所以我改变了这一点，现在图像正在上传到/resources(在 src 文件夹之外)，所以现在 angular-clie 没有刷新页面......但是它们对于 Web 应用程序不可见，因为它们不在公共文件夹中"".

At first, I was uploading the images to /src/assets Then I relized that angular-clie is refreshing the page, because it detect some new content on the folder it's listeing. So I change that and now the images are being uploading to /resources (outside src folder) so now angular-clie is not refreshing the page... But they are not vissible for the web app as they are not in the "public folder".

所以我的问题......我应该在哪里上传图像而不触发页面重新加载?/或者我如何向 angular-cli 添加异常?

So my question... Where should I upload the images without fire a page reload? / Or how I add an exception to angular-cli?

作为后端，我在 Spring 中使用 Java，这部分工作正常.我的 angular2 结构是:

As backend I'm using Java with Spring, and that part is working fine. My angular2 structure is:

/
/resources
/src
/src/app
/src/assets
/dist

等等...

上传时的控制台日志:Angular 在开发模式下运行.调用 enableProdMode() 启用生产模式.

将文件发送到后端的函数:

Function to sent file to backend:

save(event) {
    let fileList: FileList = event;
    if(fileList.length > 0) {
        let file: File = fileList[0];
        let formData:FormData = new FormData();
        formData.append('file', file, file.name);
        let headers = new Headers();
        /** No need to include Content-Type in Angular 4 */
        let options = new RequestOptions(this.createAuthHeadersForUpload());
        return this._http.post(`${this.baseUrl + '/save'}`, formData, options)
            .map((response: Response) => <JsonResponse>response.json())
            .do(function (response) {
              console.log(response);
            })
            .catch(this.handleError);
      }
      else
        return null;
  }

推荐答案

嗯，最后我不能让它在我的本地环境中工作，但我必须有一个开发环境，我可以在那里存储图像并打开它们从那里...无论如何，这不会发生在珠三角，因为我有一台 Apache 服务器.

Well, finally I couldn't make it works in my local environment, but I have to have a dev environment, where I can store the images and open them from there... Anyway, this is not happening in PRD as there I have an Apache server.
