從WSO2 API管理器調用.php的API名稱ISSUE

Question

我正在使用wso2 API管理器1.7。並需要發佈一個用PHP編寫的API。它的終點URL與.php一樣。但是，當我發佈該API並通過APIM調用它時，它從不給予任何迴應。我在碳日誌中注意到以下異常。 如果我直接使用url進行嘗試，則API會給出正確的響應。 這是一個get請求，我傳遞了url參數。

你能幫我解決這個問題嗎？內容主體是建立在

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

Answer 1

此錯誤來了。請確保您設置正確的Content-Type頭，並確保相關信息生成器在axis2.xml啓用

Answer 2

我覺得這是更好，如果你可以讓電線日誌來查看所有已通過的消息， 通過啓用電線日誌，您可以確認何時通過GET請求發送api電話，它是否正常工作 您可以啓用電線級日誌。它會記錄所有的http消息。要做到這一點

請取消註釋按照「log4j.properties」文件兩個屬性可在APIM HOME /庫/ conf目錄

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