nswag 生成的客户端响应类型错误

Question

这是在 nswag swagger 客户端生成的帮助下从 C# 控制器自动生成的 Angular 服务文件。下面的代码具有所有服务。在组件中，我试图调用 getCompanyInfoOption() api。但我没有收到从控制器发送的响应数据。

        this.baseUrl = baseUrl ? baseUrl : "https://localhost:44311";
    }

    getCompanyInfoOption(): Observable<FileResponse | null> {
        let url_ = this.baseUrl + "/api/company-info";

                try {
                    return this.processGetCompanyInfoOption(<any>response_);
                } catch (e) {

        }));
    }

    protected processGetCompanyInfoOption(response: HttpResponseBase): Observable<FileResponse | null> {
        const status = response.status;
        const responseBlob =
            response instanceof HttpResponse ? response.body :
            (<any>response).error instanceof Blob ? (<any>response).error : undefined;

        let _headers: any = {}; if (response.headers) { for (let key of response.headers.keys()) { _headers[key] = response.headers.get(key); }}
        if (status === 200 || status === 206) {
            const contentDisposition = response.headers ? response.headers.get("content-disposition") : undefined;
            const fileNameMatch = contentDisposition ? /filename="?([^"]*?)"?(;|$)/g.exec(contentDisposition) : undefined;
            const fileName = fileNameMatch && fileNameMatch.length > 1 ? fileNameMatch[1] : undefined;
            return _observableOf({ fileName: fileName, data: <any>responseBlob, status: status, headers: _headers });
        } else if (status !== 200 && status !== 204) {
            return blobToText(responseBlob).pipe(_observableMergeMap(_responseText => {
            return throwException("An unexpected server error occurred.", status, _responseText, _headers);
            }));
        }
        return _observableOf<FileResponse | null>(<any>null);
    }

如何在我的组件中调用此服务？我正在尝试使用组件的 ngOnInit 中的 subscribe 方法调用

  ngOnInit(): void {
      this.service.getCompanyInfoOption().subscribe(
        value => {
          console.log(value);
        },
        error => console.error(JSON.stringify(error)),
        () => console.log('done')
      );
  }

我在调用 getCompanyInfoOption api 后得到这个输出

Console Log

我的 c# 控制器

ASP .net core C# controller

compantInfoOption send in ok 的响应类型如下所示

conpanyInfoOption type

Answer 1

我猜生成的代码有问题，因为你的控制器返回类型不正确，尝试使用ActionResult，然后生成的api将返回正确的结果而不是期待文件响应。

你的情况

public async Task<ActionResult<CompanyInfoOptionAc>> GetCompanyInfo(){
//etc
}

Answer 2

看来你是。因为您的响应类型是 FileResponse 并且在 console.log 中您可能会看到这个对象。在数据中存储的其他内容 blob 以及如果您需要文本解释，如果它只是使用像 blobToText 这样位于生成文件末尾的函数。

如果我错了，请在问题中添加期望结果。
