当正文类型与内容类型不同时，如何处理 wso2 api 管理器中的<am:code>601000</am:code>错误？

问题描述 投票：0回答：1

我想编写一个序列，如果请求中的内容类型标头与实际请求主体类型不匹配，则返回带有 415 状态代码（“不支持的媒体类型”）的自定义错误响应。 例如，当我向 wso2 API 网关发送请求时：

 curl --location 'Https://api.llc.com/pri/sample/v1/activate' \
 --header 'Content-Type: text/csv' \
 --header 'Cookie: cookiesession1=2A041602IQFLPJ3ARNRIM9OLFBHS0DA6' \
 --data '{
 "Code": "6901",
 "clientAddress": "122.12.44.255",
 "channel": "WEB",
  }'

例如，当标题中的内容类型设置为 text/cs 并且我在正文中发送 json 时，我收到此错误：

<am:fault xmlns:am="http://wso2.org/apimanager">
<am:code>601000</am:code>
<am:type>Status report</am:type>
<am:message>Runtime Error</am:message>
<am:description>Error while building message. Error while building Passthrough 
stream</am:description>
</am:fault>

如何处理此类错误（自定义此错误并发送带有 415 错误代码的不受支持的媒体类型，因为我只想支持 json 作为正文）？ 这是我在 wso2 碳日志中遇到的错误：

我不确定为什么要构建您的消息。但是您看到此错误是因为您没有为内容类型 

text/csv
配置消息生成器。因此，将以下内容添加到您的 deployment.toml，然后您应该能够使用您在 this 问题中使用的中介策略。

[[custom_message_builders]]
content_type = "text/csv"
class="org.apache.axis2.format.PlainTextBuilder"
