WCF Web.config maxReceivedMessageSize

我发布了一个包含大量文本的json对象

下面是我当前的

web.config

。我应该如何修改以将消息大小更改为发布大json

这是紧急情况，请尽快回复。谢谢

看起来您正在使用REST，这是我以前没有做过的，所以可能有一些我不知道的注意事项

但是，json端点使用的是默认的

webHttpBinding

，它的MaxReceivedMessageSize为65536。由于要增加此值，需要定义要在配置文件中使用的webHttpBinding，为其命名，并将该名称分配给json端点的bindingConfiguration属性：

<bindings>
    <webHttpBinding>
        <binding name="myWebHttpBinding" closeTimeout="00:01:00"
                 openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                 allowCookies="false" bypassProxyOnLocal="false" 
                 hostNameComparisonMode="StrongWildcard"
                 maxBufferSize="524288" maxBufferPoolSize="524288" 
                 maxReceivedMessageSize="524288"
                 transferMode="Buffered"
                 useDefaultWebProxy="true">
            <readerQuotas maxDepth="32" maxStringContentLength=524288" 
                          maxArrayLength="16384"
                          maxBytesPerRead="4096" maxNameTableCharCount="16384" />
        </binding>
    </webHttpBinding>
</bindings>

<endpoint address="json"
                      binding="webHttpBinding" 
                      bindingConfiguration="myWebHttpBinding"
                      contract="AgricultureTradingWebApp.AgricultureWebService"
            behaviorConfiguration="webby"/>

你有什么错误吗？您是在客户端（接收响应时）还是在服务器（发送请求时）上获取它们？请求错误。实际上，它更像是524288个字符；根据使用的编码，每个字符可能有1字节，但并不总是如此。我将其视为字节，这是一个普遍的经验法则。
