【中文标题】找不到“object”类型的不同支持对象“[object Object]”。 --> 要在表格中显示的 VirusTotal JSON

【英文标题】：Cannot find a differ supporting object '[object Object]' of type 'object'. --> VirusTotal JSON to Display in a Table

【问题描述】：

我正在尝试从 VirusTotal JSON 解析数据以显示在表格中。但我无法使用 ngfor

 scan(file) 

    this.http.get("api/Scanner/").subscribe(result => 
    this.value = result;
    console.log(this.value.scans);    
    );

    

在 Html 文件中

<li *ngFor="let item of this.value.scans">
  item.version
</li>

---

   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);

                

            
        

错误

UploadComponent.html:8 ERROR Error: Cannot find a differ supporting object '[object Object]' of type 'object'. NgFor only supports binding to Iterables such as Arrays.

【问题讨论】：

你也应该分享你的角度代码

@BunyaminCoskuner 请查看更新。

console.log(this.value.scans); 行向控制台写入了什么？它是可迭代的吗？

@BunyaminCoskuner 请查看更新。

【参考方案1】：

this.value.scans 不是一个数组，而是一个对象。让我们把它转换成一个数组。

this.http.get("api/Scanner/").subscribe(result => 
    this.value = result;
    // this line will transform your object to an array
    this.value.scans = Object.keys(this.value.scans).map(key => 
        return 
            ...this.value.scans[key],
            scannerName: key
        ;
    );

);

@techno 我已经更新了我的答案。现在每个对象也有scannerName
