Question

我正在尝试使用Basic authentication type从WSO2 ESB 4.9调用第三方rest API。我已尝试在标题中使用不同的属性和授权。在WSO2 ESB中是否需要启用任何配置？谁能帮我吗？我收到以下错误：

从SOAP UI一切正常。

我的ProxyCode：

<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="TestSecureAPI"
       transports="http"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <log separator="==== Before Call ===="/>
         <property name="Authorization"
                   value="Basic API Encoded UserName/Password"
                   scope="transport"
                   type="STRING"/>
         <header name="Accept" scope="transport" value="application/json"/>
         <property name="Content-Type"
                   value="application/json"
                   scope="default"
                   type="STRING"/>
         <property name="x-tenant-domain"
                   value="test.nl"
                   scope="transport"
                   type="STRING"/>
         <call>
            <endpoint>
               <http method="GET"
                     uri-template="http://myapi.com/rest/iam/portalusers/search/hordine"/>
            </endpoint>
         </call>
         <log level="full" separator="==== After Call ===="/>

您在代理

中定义了无效的属性

检查以下属性

 <property name="Authorization"
               value="Basic "API Encoded UserName/Password"
               scope="transport"
               type="STRING"/>

无效的属性删除＆＃34;登录（"Basic "API EncodedUserName/Password"）并尝试保存代理。
