我正在制作一个用于传输文件的 WCF 服务。我只有基本的 WCF 了解并遵循 MSDN 教程:WCF Tutorial 我开始使用字节数组来传输文件,但一旦文件变得有点大(100kb 就足够了),它就会因错误请求而失败。 我按照另一个指南更改为流式传输消息,它也适用于小文件,但无法处理较大的文件(例如旧版本)。我怀疑故障出在我的配置文件中,因为 svcutil.exe 生成的配置文件没有说明任何有关流的信息。 这是我的客户 app.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IDocPublisher" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"

</binding>
</wsHttpBinding>

<client>
<endpoint address="http://localhost:8000/ServiceModelSamples/docPublisherWebService/docPublisher"

<identity>
<userPrincipalName value="Emil-PC\Emil" />
</identity>
</endpoint>
</client>
</system.serviceModel>

这是服务器 app.config

最佳答案
尝试增加客户端的发送超时和读取器配额,设置服务器端的缓冲区大小。
