我使用以下代码调用.Net核心Web API方法。但是控制台日志 undefined

 scan(file) {
    this.value = this.http.get("api/Scanner", { responseType: 'text' }).subscribe((result: any) => {
    this.value = result.Content;


    console.log(this.value);
  })
  }

 [Route("api/[controller]")]
    public class ScannerController : Controller
    {   [HttpGet]         
        public async Task<IActionResult> ScanAsync(string file_id)
        {
            //New Update //
            file_id = "./wwwroot/Upload/1";
            VirusTotal virusTotal = new VirusTotal("mykey");
            // virusTotal.UseTLS = true;         
            FileStream stream = System.IO.File.OpenRead(file_id);
            byte[] fileBytes = new byte[stream.Length];
           // stream.Seek(0, SeekOrigin.Begin);
            stream.Read(fileBytes, 0, fileBytes.Length);

            VirusTotalNet.Results.FileReport report = await virusTotal.GetFileReportAsync(fileBytes);
            bool hasFileBeenScannedBefore = report.ResponseCode == FileReportResponseCode.Present;

            Console.WriteLine("File has been scanned before: " + (hasFileBeenScannedBefore ? "Yes" : "No"));

            //If the file has been scanned before, the results are embedded inside the report.
            if (hasFileBeenScannedBefore)
            {
               return Ok(report);
            }
            else
            {
                ScanResult fileResult = await virusTotal.ScanFileAsync(fileBytes,"1");
                return Ok(fileResult);

            }

        }
    }

我需要将VT返回的结果显示为表。

http调用是异步的,因此可以得到可观察的。可观测的需要像你一样订阅,但是你不能简单地返回可观测的你不是在给你想要的值赋值,而是给可观测物本身赋值。

 this.value = this.http.get("api/Scanner", { responseType: 'text' }).subscribe((result: any) => {});

对可观察物本身的引用。你想称之为可观测的

我找到了这个解释 here

可以使用pipe/map运算符返回如下值

scan(file) {
return this.http.get("api/Scanner", { responseType: 'text' }).pipe(

 map(result => {
      //Logic or
     return result;
  })
 )
 }
