Question

我需要调用rest服务，它在标头中接受“Content-Type：application / json”，但是当我尝试从ESB调用它时。 WSO2自动添加“charset = utf-8”。我不知道如何删除它。

我也使用了ContentType属性，但没有运气。

     <property name="HTTP_METHOD" scope="axis2" type="STRING" value="PUT"/>
<property name="ContentType" scope="axis2" type="STRING" value="application/json"/>
                     <header expression="fn:concat('Basic ', get-property('ENCODED_URL'))" name="Authorization" scope="transport" xmlns:ns="http://org.apache.synapse/xsd"/>
                     <payloadFactory media-type="json">
                        <format>{
                                    "name": "XXX_Token",
                                    "type": "XXXX-cf04186e2156_sessionID",
                                    "version": "1.0.1",
                                    "Attribute-N": $1
                                    }
                        </format>
                        <args>
                                <arg expression="$ctx:XXXTokenValue" literal="false" />
                        </args>
                    </payloadFactory>
                     <property name="REST_URL_POSTFIX" scope="axis2" value=""/>
                    <call>
                        <endpoint>
                            <address trace="disable" uri="https://XXXXX:9493/governance/restservices/52b1caba-b507-4f6a-95bc-2ea7b2418e67"/>
                        </endpoint>
                    </call>

Answer 1

这是ESB 4.9.0 [1]中的一个错误。这可能已在以后的版本中修复。

请检查“/repository/conf/passthru-http.properties”中是否有以下属性

http.headers.preserve = Content-Type

（请注意，您可以添加多个标头值作为逗号分隔列表）

顺便说一下，使用属性“messageType”来设置内容类型。请参考[2]

中的messageType和ContentType上的文档
