    请指点，这与程序源文件有啥关系啊？

我是借用了sslclient.c的程序
大家看有问题吗？

adexbn

UTFCSTRING正解。

如果实在不行，就两边都转码

dagun

大家给个具体解释啊。。。。

dagun

对于这种客户端和服务端通信的问题，有时候不一定是客户端的问题，也许是服务端的问题。解决问题最好办法是在服务端设置打印信息，查看客户端给服务端发过来的SOAP头信息，以及编码格式，以及服务端是否收到过来的信息等。呵呵
关键不是问题，而是我们没有找到解决问题的方法。

dagun

现在问题是发现，如果服务端信息超过1024字节，会压缩数据gzip形式，发到客户端。我看过英文资料，说是接受时候会自动解压缩的，但是我发现如果数据过长后，客户端没有进行解压缩数据。打出如下信息：
Error 200 fault: SOAP-ENV:Client [no subcode]
"Error 200"
Detail: [no detail]

谁可以解决这个问题，相关设置我已经做过，但是还是有问题啊。

dagun

还没人回答这个问题吗，也就说客户端这边怎么设置呢？我觉得客户端没有自动去解压服务端发来的数据啊。期待。。。。
