将ASP.NET Core Web API发布到IIS时出现问题

Question

我在尝试将asp.net核心Web API项目部署到IIS时遇到麻烦。 该项目在本地主机上运行良好，但是当部署到IIS时，我在复杂的查询控制器上收到内部500错误，并且对于支架式控制器无法获得任何响应。 但是，预构建值控制器的响应很好。

我正在从mssql数据库中提取数据。

我的控制器类错了吗？ 还是我的SQL连接在IIS中不起作用？

有人可以帮我指出正确的方向吗？

这是我的控制器，启动和程序文件的屏幕截图。

我已经尝试了网上所有可用的内容。

这是我的文件的屏幕截图。

我的控制器复杂查询*****

public IEnumerable<SalesOrder> GetSalesOrder()
{
    var salesOrders = _context.SalesOrder.Include("LineItem").Select(s => new SalesOrder
    {
        // Sales orders
        id = s.id,
        orderId = s.orderId,
        creationDate = s.creationDate,
        lastModifiedDate = s.lastModifiedDate,
        legacyOrderId = s.legacyOrderId,
        orderFulfillmentStatus = s.orderFulfillmentStatus,
        orderPaymentStatus = s.orderPaymentStatus,
        sellerId = s.sellerId,
        username = s.username,
        priceSubtotal = s.priceSubtotal,
        paymentMethod = s.paymentMethod,
        paymentReferenceId = s.paymentReferenceId,
        shipToName = s.shipToName,
        addressLine = s.addressLine,
        city = s.city,
        stateOrProvince = s.stateOrProvince,
        postalCode = s.postalCode,
        countryCode = s.countryCode,
        phoneNumber = s.phoneNumber,
        email = s.email,
        shippingCarrierCode = s.shippingCarrierCode,
        estimatedDeliveryDate = s.estimatedDeliveryDate,
        dateAdded = s.dateAdded,
        // Line items
        LineItems = s.LineItems.Select(l => new LineItem
        {
            id = l.id,
            lineItemId = l.lineItemId,
            legacyItemId = l.legacyItemId,
            sku = l.sku,
            title = l.title,
            lineItemCost = l.lineItemCost,
            currency = l.currency,
            quantity = l.quantity,
            dateAdded = l.dateAdded,
            orderId = l.orderId
        })
    }).OrderByDescending(d => d.creationDate).ToList();

    return salesOrders;
}

500错误可能很多。

或者，只需将注册表项设置为您自己。 （我一直记住它们，因为我一直都在设置它们。）将HKLM \\ Software \\ Microsoft \\ Fusion \\ ForceLog注册表值设置为1，并将HKLM \\ Software \\ Microsoft \\ Fusion \\ LogPath注册表值设置为C：\\ FusionLogs或存在。

打开融合日志后，我可以立即在文件夹中看到故障。
