错误请求 - 使用对端点的调用无效 URL
Bad Request - Invalid URL using a call towards an endpoint
我一直在努力理解为什么会这样。我的 ESB 调用 https://login.microsoftonline.com/ 以获得令牌，我用它来调用端点。问题是，当通过我的 ESB 发送呼叫时，我得到：

, message = org.apache.synapse.SynapseException: Error while building message. Error while building Passthrough stream, Envelope: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body/></soapenv:Envelope>
我经历了很多场景，其中有不需要的 Cookie、Header 参数、错误的内容类型等，我使用以下字段删除了这些：
<!-- Chaning ContentType to none-->
<property name="ContentType" scope="axis2" type="STRING" value="none"/>
<!-- Removing custom Header Params -->
<property action="remove" name="x-ms-ests-server" scope="transport"/>
<property action="remove" name="x-ms-request-id" scope="transport"/>
<!-- Removing all the header params and cookies -->
<property action="remove" name="EXCESS_TRANSPORT_HEADERS" scope="axis2"/>
<property action="remove" name="TRANSPORT_HEADERS" scope="axis2"/>
<property action="remove" name="Set-Cookie" scope="transport"/>
<!-- Removing /query parameter received by the API -->
<property name="REST_URL_POSTFIX" scope="axis2" type="STRING" value=""/>
最后，我刚刚创建了一个简单的调用请求，它使用硬编码 URL、不记名令牌和所有内容直接发送到端点。 （它没有获得令牌，它跳过了那部分，因此整个过程只是对端点的一次调用）。
<property name="Authorization" scope="transport" type="STRING" value="Bearer TOKEN_IS_HERE"/>
<property name="REST_URL_POSTFIX" scope="axis2" type="STRING" value=""/>
<property action="remove" name="ContentType" scope="axis2"/>
<property name="messageType" scope="axis2" type="STRING" value="none"/>
<property name="HTTP_METHOD" scope="axis2" type="STRING" value="GET"/>
<call>
<endpoint>
<address statistics="enable" trace="enable" uri="https://sub-domain.dns.net?qparam=999999999">
<suspendOnFailure>
<initialDuration>-1</initialDuration>
<progressionFactor>1</progressionFactor>
</suspendOnFailure>
<markForSuspension>
<retriesBeforeSuspension>0</retriesBeforeSuspension>
</markForSuspension>
</address>
</endpoint>
</call>
而且我仍然不断收到错误请求 - 无效 URL。使用 postman，直接调用没有问题，我从 MI 日志中复制了所有参数。我还测试了在简化代码之前发送的每个参数，方法是手动将它们添加到邮递员要求查看它是否会坏掉，但 none 人确实坏了。我尝试了不同的 messageTypes 和 ContentTypes 但都是一样的。
这是我的 get 调用在电汇日志中的样子

我尝试的其他方法是将调用端点更改为
<endpoint>
<http method="get" uri-template="https://sub-domain.dns.net?qparam=999999999"/>
</endpoint>
但没用。任何想法都真正适用于为什么会发生这种情况。
编辑：使用 http 和 https 中的免费 API 进行测试，它们可以正常工作..

我猜目标端点可能有问题，即使它适用于 Postman..
集成工作室 7.2.0
微积分器 1.2.0
此问题已解决。问题是 https://sub-domain.dns.net?qparam=999999999 使用具有基本配置的 json 服务器。它与 Postman 一起正常工作，但由于某种原因，它无法与来自 MI 的 wso2 调用一起工作。通过 json 服务器的正确配置，问题在客户端得到解决。
我一直在努力理解为什么会这样。我的 ESB 调用 https://login.microsoftonline.com/ 以获得令牌，我用它来调用端点。问题是，当通过我的 ESB 发送呼叫时，我得到：

我经历了很多场景，其中有不需要的 Cookie、Header 参数、错误的内容类型等，我使用以下字段删除了这些：
<!-- Chaning ContentType to none-->
<property name="ContentType" scope="axis2" type="STRING" value="none"/>
<!-- Removing custom Header Params -->
<property action="remove" name="x-ms-ests-server" scope="transport"/>
<property action="remove" name="x-ms-request-id" scope="transport"/>
<!-- Removing all the header params and cookies -->
<property action="remove" name="EXCESS_TRANSPORT_HEADERS" scope="axis2"/>
<property action="remove" name="TRANSPORT_HEADERS" scope="axis2"/>
<property action="remove" name="Set-Cookie" scope="transport"/>
<!-- Removing /query parameter received by the API -->
<property name="REST_URL_POSTFIX" scope="axis2" type="STRING" value=""/>
最后，我刚刚创建了一个简单的调用请求，它使用硬编码 URL、不记名令牌和所有内容直接发送到端点。 （它没有获得令牌，它跳过了那部分，因此整个过程只是对端点的一次调用）。
<property name="Authorization" scope="transport" type="STRING" value="Bearer TOKEN_IS_HERE"/>
<property name="REST_URL_POSTFIX" scope="axis2" type="STRING" value=""/>
<property action="remove" name="ContentType" scope="axis2"/>
<property name="messageType" scope="axis2" type="STRING" value="none"/>
<property name="HTTP_METHOD" scope="axis2" type="STRING" value="GET"/>
<call>
<endpoint>
<address statistics="enable" trace="enable" uri="https://sub-domain.dns.net?qparam=999999999">

<markForSuspension>

</markForSuspension>
</address>

</call>
而且我仍然不断收到错误请求 - 无效 URL。使用 postman，直接调用没有问题，我从 MI 日志中复制了所有参数。我还测试了在简化代码之前发送的每个参数，方法是手动将它们添加到邮递员要求查看它是否会坏掉，但 none 人确实坏了。我尝试了不同的 messageTypes 和 ContentTypes 但都是一样的。
这是我的 get 调用在电汇日志中的样子

我尝试的其他方法是将调用端点更改为
<endpoint>
<http method="get" uri-template="https://sub-domain.dns.net?qparam=999999999"/>
</endpoint>
但没用。任何想法都真正适用于为什么会发生这种情况。

我猜目标端点可能有问题，即使它适用于 Postman..
集成工作室 7.2.0 微积分器 1.2.0
此问题已解决。问题是 https://sub-domain.dns.net?qparam=999999999 使用具有基本配置的 json 服务器。它与 Postman 一起正常工作，但由于某种原因，它无法与来自 MI 的 wso2 调用一起工作。通过 json 服务器的正确配置，问题在客户端得到解决。
