我在Azure应用服务上部署了两个ASP.NET Core 7应用程序。对于某些请求，service1需要在私有vnet上向service2发出POST请求。这在我们的暂存环境中工作正常。然而，在我们的生产环境中，由于某种原因，POST被转换为GET，导致请求失败。
.NET Core将传出的POST请求转换为GET的原因是什么？
上下文-向Refit添加额外的日志记录：

services
    .AddRefitClient<IService2Api>(
        (sp) =>
            new RefitSettings
            {
                CollectionFormat = CollectionFormat.Multi,
                HttpMessageHandlerFactory = () =>
                    new LoggingHandler(
                        sp.GetRequiredService<ILoggerFactory>()
                            .CreateLogger<LoggingHandler>(),
                        new HttpClientHandler() { AllowAutoRedirect = true }
                    )
            }
    )
    .ConfigureHttpClient(
        // ...

LoggingHandler：

private class LoggingHandler : DelegatingHandler
{
    private readonly ILogger<LoggingHandler> logger;

    public LoggingHandler(ILogger<LoggingHandler> logger, HttpMessageHandler innerHandler)
        : base(innerHandler)
    {
        this.logger = logger;
    }

    protected override HttpResponseMessage Send(
        HttpRequestMessage request,
        CancellationToken cancellationToken
    )
    {
        logger.LogDebug("Before [{Method}] to {Url}", request.Method, request.RequestUri);
        var response = base.Send(request, cancellationToken);
        logger.LogDebug("After [{Method}] to {Url}", request.Method, request.RequestUri);
        return response;
    }

    protected override async Task<HttpResponseMessage> SendAsync(
        HttpRequestMessage request,
        CancellationToken cancellationToken
    )
    {
        logger.LogDebug("Before [{Method}] to {Url}", request.Method, request.RequestUri);
        var response = await base.SendAsync(request, cancellationToken);
        logger.LogDebug("After [{Method}] to {Url}", request.Method, request.RequestUri);
        return response;
    }
}
