wso2 Data Services REST POST Format JSON

Question

J'essaie (vraiment fort) de créer un service de données dans WSO2 EI611 que je peux appeler dans JSON. Mais je n'ai aucune idée du format JSON à utiliser lorsque je poste mes données au service. J'ai essayé beaucoup de format mais j'ai l'erreur Null.

Merci d'avance.

Voici mon code de service de données:

<data name="OAuthToken" serviceGroup="" serviceNamespace=""> 
     <description/> 
     <config id="QT_DB"> 
     <property name="org.wso2.ws.dataservice.user">wso2</property> 
     <property name="org.wso2.ws.dataservice.password">wso2</property> 
     <property name="org.wso2.ws.dataservice.protocol">jdbc:mysql://192.168.1.10:3306/QT_DB</property> 
     <property name="org.wso2.ws.dataservice.driver">com.mysql.jdbc.Driver</property> 
     </config> 
     <query id="AddNewToken" useConfig="QT_DB">

     </query> 
    </data> 

Voici le POST J'essaie de faire:

{ 
    "AddNewToken2": { 
     "ACCESS_TOKEN": "2GQL1fo_bHv9GwIALgMhF5cuxynFrbHC0", 
     "TOKEN_TYPE": "Bearer", 
     "API_SERVER": "https://api04.iq.questrade.com/", 
     "CREATED": "2017-09-10T15:05:21.000-04:00", 
     "EXPIRES_IN": "1800", 
     "EXPIRATION": "2017-09-10T15:05:21.000-04:00", 
     "REFRESH_TOKEN": "bz8O65CN9HYA2ripBhV9M5q7He65Ebls0" 
    } 
} 

Et l'erreur que je reçois:

[2017-09-10 22:59:07,433] [EI-Core] ERROR - ServerWorker Error processing POST reguest for : /services/OAuthToken.HTTPEndpoint/AddNewToken2. Error detail: null.

Answer 1

Lorsque vous envoyez la demande POST, la charge utile de la demande doit être comme suit.

{ 
    "_postAddNewToken2": { 
     "ACCESS_TOKEN": "2GQL1fo_bHv9GwIALgMhF5cuxynFrbHC0", 
     "TOKEN_TYPE": "Bearer", 
     "API_SERVER": "https://api04.iq.questrade.com/", 
     "CREATED": "2017-09-10T15:05:21.000-04:00", 
     "EXPIRES_IN": "1800", 
     "EXPIRATION": "2017-09-10T15:05:21.000-04:00", 
     "REFRESH_TOKEN": "bz8O65CN9HYA2ripBhV9M5q7He65Ebls0" 
    } 
}
