如何从Flex代码向wcf服务发送更大的字节或通过wcf服务接收更大的字节 [英] How to send larger size of byte to wcf service from flex code or receive larger bytes by wcf service

问题描述

我正在将图像转换为flex字节，然后将字节发送到wcf服务，当它较小时，它可以正常工作，但是当它较大时，它不起作用，并显示出皂响应错误或404错误....是我的WCF服务中的Web配置文件...

在我的wen配置中添加了这些行……算出来了..

I am converting a image into bytes in flex and sending bytes to wcf service it works fine when it is in smaller size but when size is more it is not working and showing that soap response error or 404 error....here is my web config file which is in my wcf services...







<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
     </system.web>
    <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

I guess you are using WCF 4.0.In that you have to find out the tags that are used for configuration.here is a sample of configuration tags that are used in WCF3.0.You can try and look up in the web the same WCF 4.0



<custombinding>        
        <binding name="LargeCustomBinding">
                 receiveTimeout="01:00:00" 
                 openTimeout="01:00:00" 
                 closeTimeout="01:00:00" 
                 sendTimeout="01:00:00">
          <binarymessageencoding>
            maxReadPoolSize="2147483647" 
            maxSessionSize="2147483647" 
            maxWritePoolSize="2147483647">
            <readerquotas>
              maxArrayLength="2147483647" 
              maxDepth="2147483647" 
              maxBytesPerRead="2147483647" 
              maxNameTableCharCount="2147483647" 
              maxStringContentLength="2147483647" />
          </readerquotas></binarymessageencoding>
          <httptransport>
            maxBufferSize="2147483647" 
            maxReceivedMessageSize="2147483647" 
            maxBufferPoolSize="2147483647"/>
        </httptransport></binding>
      </custombinding>

Added these lines in my wen config......it worked out..







<basichttpbinding>   

        <binding>

 maxReceivedMessageSize="2147483647"  closeTimeout="00:10:00"  maxBufferPoolSize="2147483647"

                    openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxBufferSize="2147483647"

          <readerquotas>
