Question

我正在使用wso2 API manager 1.7。并需要发布用PHP编写的API。它的端点网址是.php aslo。但是当我发布该API并通过APIM调用它时，它从不给出任何响应。我注意到碳日志中有以下异常。如果我直接尝试使用url，API会给出正确的响应。这是一个get请求，我正在传递url参数。

能帮助我解决这个问题。

API URL : <host>/api/testApi.php

构建内容正文时会出现此错误。确保设置正确的内容类型标头，并确保在axis2.xml中启用了相关的消息生成器

Answer 2

我觉得它更好如果您可以启用有线日志来查看所有正在通过的消息， 通过启用有线日志，您可以确认何时通过GET请求发送api呼叫它是否正常工作 您可以启用线级日志。它将记录所有http消息。这样做

请取消注释＆＃34; log4j.properties＆＃34;中的两个属性。文件可以在APIM HOME / repository / conf目录中找到

log4j.logger.org.apache.synapse.transport.http.wire=DEBUG

带有.php的API名称，从WSO2 API管理器ISSUE调用
