如何使用 WSO2 API Manager 将租户设置为中介中的标头 [英] How to set tenant to header in mediator with WSO2 API Manager

问题描述

我有一个需要租户作为标头的 API.

I have an API that requires the tenant as a header.

如果我创建自定义顺序:

If I create a custom in-sequence:

<sequence name="WSO2AM--Ext--In">
    <header
       name="X-Tenant-Id"
       scope="transport"
       action="set"
       expression="???????????????????"
    />
</sequence>

有没有我可以使用的表达方式来实现这一点?还是我应该创建一个每个 API 的中介来设置它?

Is there an expression that I can use to achieve this? Or should I resort to creating a per-API mediator to set it?

附注:查看 WSO2 源代码(CarbonTenantInfoConfigurator.java)，我发现这个片段可以用作提示:

PS: Looking at WSO2 source code (CarbonTenantInfoConfigurator.java), I found this fragment that could be useful as a hint:

PrivilegedCarbonContext cc = PrivilegedCarbonContext.getThreadLocalCarbonContext();
String tenantDomain = cc.getTenantDomain();
int tenantId = cc.getTenantId();
messageContext.setProperty("tenant.info.domain", tenantDomain);
messageContext.setProperty("tenant.info.id", tenantId);

但如果可能的话，我不知道如何访问自定义序列中的这些属性.

But I don't know how to access to those properties in the custom sequence, if possible.

推荐答案

在检查 ApiManager 的调试输出后，我注意到自定义序列在处理程序之后立即执行.幸运的是，OAuthAuthenticator 类(由 APIAuthenticationHandler 使用)设置了一些方便的属性，例如 END_USER_NAME 和 APPLICATION_NAME.

After checking the debug output from ApiManager, I noticed that custom sequences are being executed right after handlers. Luckily, the OAuthAuthenticator class (used by APIAuthenticationHandler) sets some handy properties like END_USER_NAME and APPLICATION_NAME.

END_USER_NAME 包含调用者的姓名和租户 ([e-mail]).

END_USER_NAME contains the name and tenant of the caller ([e-mail]).

这个自定义序列对我有用:

This custom sequence worked for me:

<sequence name="add_service_header" trace="enable" statistics="enable" xmlns="http://ws.apache.org/ns/synapse">
    <log/>
    <property name="tenant" expression="fn:substring-after(get-property('END_USER_NAME'), '@')" />
    <header name="X-Tenant" scope="transport" expression="get-property('tenant')"/>
    <header name="X-AppName" scope="transport" expression="get-property('APPLICATION_NAME')"/>
</sequence>
