node.js - Angular Universal 和 Express JS 连接因未知 url 的 Http 失败响应而被拒绝 控制台中的错误

Question

我一直在尝试让 Angular Serverside Rendering 工作，我已经到了静态部分可以完美工作的地步，但是对于 API 调用，我得到一个 HttpErrorResponse - 控制台中未知 url 错误的 Http 失败响应，这是相同的错误当 API 服务器关闭时，我得到了。我没有使用任何相对 URL 进行 API 调用，它的所有绝对 URL 都带有 https。

HttpErrorResponse {
  headers:
   HttpHeaders { normalizedNames: Map {}, lazyUpdate: null, headers: Map {} },
  status: 0,
  statusText: 'Unknown Error',
  url: null,
  ok: false,
  name: 'HttpErrorResponse',
  message: 'Http failure response for (unknown url): 0 Unknown Error',
  error:
   ProgressEvent {
     type: 'error',
     target:
      XMLHttpRequest {
        onloadstart: null,
        onprogress: null,
        onabort: null,
        onerror: null,
        onload: null,
        ontimeout: null,
        onloadend: null,
        _listeners: [Object],
        onreadystatechange: null,
        _anonymous: undefined,
        readyState: 4,
        response: null,
        responseText: '',
        responseType: 'text',
        responseURL: '',
        status: 0,
        statusText: '',
        timeout: 0,
        upload: [XMLHttpRequestUpload],
        _method: 'POST',
        _url: [Url],
        _sync: false,
        _headers: [Object],
        _loweredHeaders: [Object],
        _mimeOverride: null,
        _request: null,
        _response: null,
        _responseParts: null,
        _responseHeaders: null,
        _aborting: null,
        _error: null,
        _loadedBytes: 0,
        _totalBytes: 0,
        _lengthComputable: false },
     currentTarget:
      XMLHttpRequest {
        onloadstart: null,
        onprogress: null,
        onabort: null,
        onerror: null,
        onload: null,
        ontimeout: null,
        onloadend: null,
        _listeners: [Object],
        onreadystatechange: null,
        _anonymous: undefined,
        readyState: 4,
        response: null,
        responseText: '',
        responseType: 'text',
        responseURL: '',
        status: 0,
        statusText: '',
        timeout: 0,
        upload: [XMLHttpRequestUpload],
        _method: 'POST',
        _url: [Url],
        _sync: false,
        _headers: [Object],
        _loweredHeaders: [Object],

        _request: null,
        _response: null,
        _responseParts: null,
        _responseHeaders: null,
        _aborting: null,
        _error: null,
        _loadedBytes: 0,
        _totalBytes: 0,
        _lengthComputable: false },
     lengthComputable: false,
     loaded: 0,
     total: 0 } }
