I have a situation where I have to parse the result of a webpage. In this case, the website does not offer an API to consume to retrieve this data. I have created a flow that calls the website but states:

消息:发送HTTP请求时出错.消息有效负载的类型为:NullPayload

Any help would be much appreciated.

<http:request-config name="HTTP_Request_Configuration"   host="http://www.resellerratings.com/" port="80" doc:name="HTTP Request Configuration" basePath="/"/>
<flow name="testFlow">
    <http:listener config-ref="HTTP_Listener_Configuration" path="/testReseller" allowedMethods="GET" doc:name="HTTP"/>
    <http:request config-ref="HTTP_Request_Configuration" path="/store/best_buy" method="GET" doc:name="HTTP" sendBodyMode="NEVER"/>
    <logger message="#[message]" level="INFO" doc:name="Logger"/>
</flow>

推荐答案

鉴于您的配置，它可能由于host属性而失败，因为它不应该包含协议.尝试以下方法:

Given your configuration, it probably fails because of the host attribute since it shouldn't include the protocol. Try this instead:

<http:request-config name="HTTP_Request_Configuration" host="www.resellerratings.com" port="80" doc:name="HTTP Request Configuration" /> <flow name="testFlow"> <http:listener config-ref="HTTP_Listener_Configuration" path="/testReseller" allowedMethods="GET" doc:name="HTTP"/> <http:request config-ref="HTTP_Request_Configuration" path="/store/best_buy" method="GET" doc:name="HTTP" sendBodyMode="NEVER"/> <logger message="#[message]" level="INFO" doc:name="Logger"/> </flow>

<http:request-config name="HTTP_Request_Configuration" host="www.resellerratings.com" port="80" doc:name="HTTP Request Configuration" /> <flow name="testFlow"> <http:listener config-ref="HTTP_Listener_Configuration" path="/testReseller" allowedMethods="GET" doc:name="HTTP"/> <http:request config-ref="HTTP_Request_Configuration" path="/store/best_buy" method="GET" doc:name="HTTP" sendBodyMode="NEVER"/> <logger message="#[message]" level="INFO" doc:name="Logger"/> </flow>
