Question

我是wso2 esb服务器的新用户，我正在尝试创建代理服务以连接到休息服务。我在“部署服务＆＃34;”中试图测试代理时遇到问题。 esb的页面。代理服务的源视图是：

> <?xml version="1.0" encoding="UTF-8"?>
>       <proxy xmlns="http://ws.apache.org/ns/synapse"
>        name="search"
>        transports="https,http,local"
>        statistics="disable"
>        trace="disable"
>        startOnLoad="true">
>      <target>
>       <outSequence>
>          <send/>
>       </outSequence>
>       <faultSequence>
>          <log level="full" category="DEBUG"/>
>       </faultSequence>
>       <endpoint>
>          <http method="get" uri-template="http://52.24.50.197:8080/search"/>
>          <property name="q" value="test"/>
>       </endpoint>    </target>    <description/> </proxy>

我点击＆＃34;尝试此服务＆＃34;链接，我在控制台中得到这个：

有人可以向我解释为什么数据没有回来。我们已经打开了服务所在服务器的端口，即8080端口。

由于

Answer 1

您似乎指向ESB中的错误网址。日志显示收到的以下URI消息：/ services / mediate / mediate。由于您的代理名为“搜索”，因此应该是链接/服务/搜索。

另外，我看到你的http端点模板没有采用任何参数，这可能不是你想要的。

发送中介应该看起来像这样：

<inSequence>
   <!-- Assigns URI-Template var to some value. You could use an expression here too -->
   <property name="uri.var.search" value="test"/>
</inSequence>
<outSequence>
    <send/>
</outSequence>
<endpoint>
    <html uri-template="http://52.24.50.197:8080/search?q={uri.var.search}" method="GET"/>
</endpoint>

Answer 2

而是在代理外部定义您的端点，因此在ESB主控制台中创建您的端点：

<endpoint xmlns="http://ws.apache.org/ns/synapse" name="HTTPEndpoint">
            <http uri-template="http://{uri.var.ip}:8080/{uri.var.servicepath} method="GET">
            </http>
</endpoint>

然后试试这个代理：

<?xml version="1.0" encoding="UTF-8"?>
       <proxy xmlns="http://ws.apache.org/ns/synapse" name="search"
        transports="https,http,local"
        statistics="disable"
        trace="disable"
        startOnLoad="true">
        <target>
        <inSequence>
            <property name="uri.var.ip" value="52.24.50.197"/>
            <property name="uri.var.servicepath" value="search"/>
            <send>
                <endpoint key="MyHTTPEndpoint"/>
            </send>
        </inSequence>
        <outSequence>
          <respond/>
        </outSequence>
        <faultSequence>
          <log level="full" category="DEBUG"/>
        </faultSequence>
        </target>    <description/> </proxy>

因此，您将把get请求发送到代理端点，将其转发给服务，并希望显示响应。
