我必须使用相互身份验证从 java 调用安全的 WCF 服务。 一切正常，除了我无法发送大于 48680 字节的消息。因此，48680 字节的消息已成功发送，但 48681 字节的消息未成功发送，Java 应用程序因读取超时异常而失败，尽管 WCF 的配额设置允许更大的消息。

那么可能是什么问题呢？

我已经用 .net WCF 客户端测试了该服务，它能够成功调用该服务，所以我想知道可能是什么问题？为什么 WCF 客户端能够调用服务和 Java 客户端，即使使用带有 UrlConnection 的普通 HTTP POST 请求，也不能？

更新

这是肥皂消息的示例

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <DoSomethingUseful xmlns="http://namespace/2012/01/service">
        ...
        </DoSomethingUseful>
    </soap:Body>
</soap:Envelope>

更新

有人告诉我在 .net 服务端有 "Client certificate is required. No certificate was found in the request"似乎在 ssl session 恢复时出现的消息。只有当 Content-Length 大于 48680 字节时才会发生。 WCF 服务还配置了 basicHttpBinding 以使用传输级安全性。

最佳答案

您是否尝试查看正在发送的实际数据包 - 例如。使用 tcpdump/Wireshark ( http://www.wireshark.org/ ) ?

我曾经只在某些平台上遇到过问题，该平台访问的是非常挑剔的 SSL 卸载引擎背后的服务。

关于java - 无法发送 48681 字节的消息来保护来自 java 的 wcf 服务，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9046593/
