如何在Rampart/C(Axis2/C)中反序列化SAML断言？

Question

我在utf-8 char *缓冲区中有SAML 1.1和SAML 1.0响应,我想将它们转换为Rampart/C saml_response_t *对象.我的问题是:

saml_response_t从字符串创建a的正确方法是什么？

理想情况下,我想在C中使用代码示例来执行此操作,然后以正确的顺序处理各种解析器工具,因为Axis2/C对于如何释放内存有一些奇怪的想法.

我这样做的努力遇到了失败,主要是因为内存故障,但这就是我所拥有的.请记住,该deserialize_buffer()方法正如它所说的那样 - 将缓冲区转换为a axiom_node_t *,但我也愿意替换它.

/* : get the raw XML from the SAML assertion */
xml_data = Tcl_GetStringFromObj (objv[2], &xml_length);

/* : parse the response XML for processing */
stream = gstream_mem_create (xml_data, xml_length);
node = Axis2_axiom_deserialize_buffer (env, stream);

/* : build a SAML response from the parsed XML */
saml_response = saml_response_create (env);
saml_response_build (saml_response, node, env);
arraylist = saml_response_get_assertions (saml_response, env);

/* : create our return value object */
obj = Tcl_NewListObj (0, NULL);

/* :- convert the SAML assertion into a string */
for (i = 0;
     i < axutil_array_list_size (arraylist, env);
         i++) {
    saml_assertion = (saml_assertion_t *) axutil_array_list_get (arraylist, env, i);
    if (saml_assertion != NULL) {
        assertion_node = saml_assertion_to_om (saml_assertion, NULL, env);

        element = Tcl_NewStringObj (axiom_node_to_string (node, env), -1);
        Tcl_ListObjAppendElement (interp, obj, element);

        axiom_node_free_tree (assertion_node, env);
    }
}
