如何通过WSO2 ESB发出API请求

Question

我已按照本教程中给出的步骤进行操作。

https://docs.wso2.com/display/ESB500/Sending+a+Simple+Message

一切都正确完成，但是当我尝试通过ESB（通过8280端口）调用api时，显示错误代码202。 即使我没有指定任何故障顺序。

我已经正确尝试了每个步骤，并且还确保api的端点正常工作。

我也做了示例...在这里您有我的配置：-端点定义（右键单击示例->端点->创建新端点）-

<endpoint name="QueryDoctorEP" xmlns="http://ws.apache.org/ns/synapse">
    <http method="get" uri-template="http://wso2training-restsamples.wso2apps.com/healthcare/{uri.var.category}"/>
</endpoint>

-我的api定义（右键单击示例-> API Rest->创建新的API Rest）

<?xml version="1.0" encoding="UTF-8"?>
<api context="/healthcare" name="HealthcareAPI" xmlns="http://ws.apache.org/ns/synapse">
    <resource methods="GET" uri-template="/querydoctor/{category}">
        <inSequence>
            <log description="Request Log" level="custom">
                <property name="message" value="Welcome to HealthcareService"/>
            </log>
            <send>
                <endpoint key="QueryDoctorEP"/>
            </send>
        </inSequence>
        <outSequence>
            <send/>
        </outSequence>
        <faultSequence/>
    </resource>
</api>

等待服务器部署配置...请求：（我的偏移量是3）

curl -v http://localhost:8283/healthcare/querydoctor/surgery

在这里你有卷曲的反应
