帶有.php的API名稱，從WSO2 API管理器ISSUE調用

Question

我正在使用wso2 API manager 1.7。 並需要發布用PHP編寫的API。 它的端點網址是.php aslo。 但是當我發布該API並通過APIM調用它時，它從不給出任何響應。 我注意到碳日志中有以下異常。 如果我直接嘗試使用url，API會給出正確的響應。 這是一個get請求，我正在傳遞url參數。

你能幫我解決一下這個問題。

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

構建內容正文時會出現此錯誤。 確保設置正確的內容類型標頭，並確保在axis2.xml中啟用了相關的消息生成器

Answer 2

我認為這樣更好如果您可以啟用有線日志來查看所有正在通過的消息， 通過啟用有線日志，您可以確認何時通過GET請求發送api呼叫它是否正常工作您可以啟用線路級別日志。 它將記錄所有http消息。 去做這個

請取消注釋“log4j.properties”文件中的兩個屬性，該文件可在APIM HOME / repository / conf目錄中找到
