.net - 发送soap请求时刷新XmlSerializer缓冲区时出错（存档条目是使用不受支持的压缩方法压缩的。）

Question

尝试从 .NET Core 3.1 向无处不在的点对点支付平台发送请求时出现错误。该代码对于自动生成的 SOAP 来说是相当标准的，但这里是我试图序列化的自动生成模型：

    [System.Diagnostics.DebuggerStepThroughAttribute()]

    public partial class EbMtvnSvcReq
    {
        
        private MtvnSvcVerType mtvnSvcVerField;
        
        private string msgUUIDField;
        
        private PrcsParmsType prcsParmsField;
        
        private ServiceRequestType[] svcField;
        
        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Order=0)]
        public MtvnSvcVerType MtvnSvcVer
        {
            get
            {
                return this.mtvnSvcVerField;
            }
            set
            {
                this.mtvnSvcVerField = value;
            }
        }
        
        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(Order=1)]
        public string MsgUUID
        {
            get
            {
                return this.msgUUIDField;
            }
            set
            {
                this.msgUUIDField = value;
            }
        }
        
        /// <remarks/>

        public PrcsParmsType PrcsParms
        {

            {
                return this.prcsParmsField;
            }
            set
            {
                this.prcsParmsField = value;
            }
        }
        
        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute("Svc", Order=3)]
        public ServiceRequestType[] Svc
        {
            get
            {
                return this.svcField;
            }
            set
            {
                this.svcField = value;
            }
        }
    }

抛出异常：

我遵循了内部代码，尝试刷新缓冲区似乎失败了。

有没有人对此有任何见解？

我通过在 GetBindingForEndpoint 方法中将缓冲区值设置为较低的值（比 int.Max）解决了这个问题：

        System.ServiceModel.BasicHttpsBinding result = new System.ServiceModel.BasicHttpsBinding();
        result.MaxBufferSize = 1024000;
        result.ReaderQuotas = System.Xml.XmlDictionaryReaderQuotas.Max;
        result.MaxReceivedMessageSize = 1024000;
        result.MaxBufferPoolSize = 524288;
        ...
        result.TextEncoding = System.Text.Encoding.BigEndianUnicode;
        result.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
        return result;
