Question

我在wso2am 1.9.1中使用org.apache.synapse.commons.json.JsonStreamBuilder和org.apache.synapse.commons.json.JsonStreamFormatter，我没有遇到JSON问题格式错误，但是在wso2am 1.10.0中，我收到了这个错误：

是的，我的应用程序中存在JSON格式错误，但我现在无法修复此问题，有一种方法可以获得与wso2am 1.9.1相同的行为吗？这是一个错误或api经理不必传递JSON格式错误？

已编辑：如果我使用org.apache.axis2.json.JSONStreamFormatter和org.apache.axis2.json.JSONStreamBuilder，我没有遇到问题，但我看到的是导致原型APIS失败，改变此配置后GET方法不起作用。

谢谢

一种解决方法是将消息构建为纯文本内容。您可以使用以下构建器。

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

您可能在Content-Lenght标头中输入了错误的值。删除标题Content-Length。
