WSO2 API管理器3.2.0POST头中的额外文本

Question

我一直在试用SOAPAPIManager3.2.0来为SOAP服务生成REST，并且已经成功地遍历了这些过程。我启用了消息线跟踪，以便查看日志中的请求-响应。我可以看到，正在创建一条格式正确的消息并将其发送到后端服务，但是响应并不像预期的那样。我注意到一些额外的文本(通常是"16e“，如第二行到最后一行)是在XML有效负载之前发送的，因此正在作为有效负载进行处理。我怀疑这是我的问题的原因，但我无法追踪它的来源。

当我使用XML请求并直接调用后端SOAP服务时，我将获得一个成功的响应。你知道这篇文章的责任是什么吗?我需要做些什么来摆脱它？你的帮助将不胜感激。

我从https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Transfer-Encoding#directives那里得到了16e的来源

块

数据以一系列块的形式发送。在本例中，内容长度标题被省略，在每个块的开头，您需要以十六进制格式添加当前块的长度，后面是'\r\n‘，然后是块本身，然后是另一个'\r\n’。终止块是一个常规块，但其长度为零为例外。它后面跟着拖车，它由实体头字段(可能是空的)序列组成。

问题原来是内容类型的问题。我发送值"application/soap+ xml“并将其更改为"text/xml”，方法是在/repository/deployment/server/synapse-configs/default/api/中找到的api的xml配置文件中添加下面一行

<property name="ContentType" value="text/xml" scope="axis2" type="STRING"/>

这就是让它运转所需的全部条件。
