为什么在 WSO2 ESB 中我不能创建两个具有相同上下文值的不同 API？
Why in WSO2 ESB I can't create two different APIs having the same context value?
我不太喜欢 WSO2 ESB，我遇到了以下问题。
在我的 ESB 项目中，我有 2 个不同的 API，它们具有 相同的上下文 但处理不同的 URL。
1) 第一个被命名为 CommoditiesInACountry 并且它是这样定义的：
<?xml version="1.0" encoding="UTF-8"?>
<api context="/country" name="CommoditiesInACountry" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/{localizationId}/commodities">
..............................................................
..............................................................
..............................................................
2) 第二个被命名为 CommodityInLocationMarkets 并且它是这样定义的：
<?xml version="1.0" encoding="UTF-8"?>
<api context="/country" name="CommodityInLocationMarkets" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/{localizationId}/commodity/{commodityId}">
..............................................................
..............................................................
..............................................................
所以你可以看到两者具有相同的上下文，其值为 /country 但是 2 APIs 处理不同的 URLs，事实上第一个处理资源 .../country/{localizationId}/commodities 第二个处理资源 .../country/{localizationId}/commodity/ {商品编号}
问题是，当我部署我的 Carbon 应用程序时，我收到以下错误消息，该消息与我有 2 个具有相同上下文值的不同 API 相关：

更改已正确部署在我的 Carbon 服务器上的 2 APIs 上下文值之一。
我的问题是我需要这两个 API 的 URL 以 .../country 开头上下文值。
WSO2 ESB 怎么可能不允许两个 API 具有相同的上下文？我怎样才能创建两个不同的 APIs 都具有 URL 像：XXX.YYY.ZZZ.RRR/country/...
是否可以使用 WSO2 ESB?
一个可能的解决方案（如果错误请纠正我）可能是我的 API 有两个不同的联系方式，然后将其映射到 WSO2 API MANAGER 在这里定义最终用户消费的最终 URL。
有什么解决方案？
ESB/APIM 不允许创建具有相同上下文的 2 个 API。但是，您可以使用一个 API 并拥有多个这样的资源。
<?xml version="1.0" encoding="UTF-8"?>
<api context="/country" name="CommoditiesInACountry" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/{localizationId}/commodities">
................................
................................
</resource>
<resource methods="GET" uri-template="/{localizationId}/commodity/{commodityId}">
................................
................................
</resource>
</api>
相关说明：要遵守 REST 标准，您的第二个资源应该是 /{localizationId}/commodities/{commodityId}
我不太喜欢 WSO2 ESB，我遇到了以下问题。
在我的 ESB 项目中，我有 2 个不同的 API，它们具有 相同的上下文 但处理不同的 URL。
1) 第一个被命名为 CommoditiesInACountry 并且它是这样定义的：
<?xml version="1.0" encoding="UTF-8"?>
<api context="/country" name="CommoditiesInACountry" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/{localizationId}/commodities">
..............................................................
..............................................................
..............................................................
2) 第二个被命名为 CommodityInLocationMarkets 并且它是这样定义的：
<?xml version="1.0" encoding="UTF-8"?>
<api context="/country" name="CommodityInLocationMarkets" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/{localizationId}/commodity/{commodityId}">
..............................................................
..............................................................
..............................................................
所以你可以看到两者具有相同的上下文，其值为 /country 但是 2 APIs 处理不同的 URLs，事实上第一个处理资源 .../country/{localizationId}/commodities 第二个处理资源 .../country/{localizationId}/commodity/ {商品编号}
问题是，当我部署我的 Carbon 应用程序时，我收到以下错误消息，该消息与我有 2 个具有相同上下文值的不同 API 相关：

更改已正确部署在我的 Carbon 服务器上的 2 APIs 上下文值之一。
我的问题是我需要这两个 API 的 URL 以 .../country 开头上下文值。
WSO2 ESB 怎么可能不允许两个 API 具有相同的上下文？我怎样才能创建两个不同的 APIs 都具有 URL 像：XXX.YYY.ZZZ.RRR/country/...
是否可以使用 WSO2 ESB?
一个可能的解决方案（如果错误请纠正我）可能是我的 API 有两个不同的联系方式，然后将其映射到 WSO2 API MANAGER 在这里定义最终用户消费的最终 URL。
有什么解决方案？
ESB/APIM 不允许创建具有相同上下文的 2 个 API。但是，您可以使用一个 API 并拥有多个这样的资源。
<?xml version="1.0" encoding="UTF-8"?>
<api context="/country" name="CommoditiesInACountry" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="GET" uri-template="/{localizationId}/commodities">
................................
................................
</resource>
<resource methods="GET" uri-template="/{localizationId}/commodity/{commodityId}">
................................
................................
</resource>
</api>
相关说明：要遵守 REST 标准，您的第二个资源应该是 /{localizationId}/commodities/{commodityId}
