是否可以处理来自呼叫中介的 HTML 响应？

Question

无论我尝试了什么——将正文丰富到 ​​STRING 属性，记录响应——我总是得到一个异常，这可能与 html 不是正确的 xml 有关。我根本不需要遍历 html，我只需要将它存储为字符串属性。

查看axis2.xml

对于像这样的 html mime 类型应该有 messageBuilder：

    <messageBuilder contentType="text/html" 
                    class="org.apache.axis2.format.PlainTextBuilder"/>

如果它未注释并且您仍然有错误，请检查 mime-type 标头作为响应。
