红est在远程服务器上返回状态代码415，在本地200

Question

背景知识

我正在构建一个API，以从无法更改的旧版系统接收数据。它将XML发布到我们的API，我们将其转换为JSON，然后使用JSON建模绑定到我们的EF类，并将数据保存到数据库中以供以后读取。

该服务器是运行RHEL 7的Ec2。

控制器方法

[HttpPost]
    public async Task<IActionResult> ReceivePurchaseOrder()
    {
        using (var reader = new StreamReader(Request.Body))
        {
            var content = await reader.ReadToEndAsync();

            var json = _documentConverter.XmlToJson(content);

            var command = JsonConvert.DeserializeObject<ReceivePurchaseOrderCommand>(json, new JsonSerializerSettings
            {
                ContractResolver = new DefaultContractResolver()
                {
                    NamingStrategy = new SnakeCaseNamingStrategy()
                }
            });

            var response = await Mediator.Send(command);
            return OkOrNotFound(response);

        }

    }

Startup.cs

public void ConfigureServices(IServiceCollection services)
    {
        services.AddResponseCompression();
        services.AddMvc(config =>
        {
            // Add XML Content Negotiation
            config.RespectBrowserAcceptHeader = true;
            config.InputFormatters.Add(new XmlSerializerInputFormatter());
            config.OutputFormatters.Add(new XmlSerializerOutputFormatter());
        }).AddJsonOptions(options =>
        {
            options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
        });
        services.AddMediatR();
        services.AddTransient(typeof(IPipelineBehavior<,>), typeof(ValidationBehavior<,>));
        services.AddAutoMapper();
        services.AddAssemblyInfo();
        services.AddAppConfig(Configuration);
        services.AddAppUnitOfWork(Configuration);
        services.AddSingleton<IDocumentConverter, DocumentConverter>();
        services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
        services.AddSingleton<IEmailService, EmailService>();
        services.AddSingleton<IExceptionEmailService, ExceptionEmailService>();
        services.AddValidators();
    }
