我正在尝试构建与 Integration Studio 的集成，它必须通过多个服务并将响应发送到后端端点。这工作得很好，直到它尝试调用后端，然后它进入超时状态。
这里是 XML
<?xml version="1.0" encoding="UTF-8"?>
<api context="/salesforce" name="SFApi" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="POST" uri-template="/anagrafiche">
<inSequence>
<property expression="$body//username" name="uri.var.username" scope="default" type="STRING"/>
<property expression="$body//password" name="uri.var.password" scope="default" type="STRING"/>
<property expression="$body//client_id" name="uri.var.client_id" scope="default" type="STRING"/>
<property expression="$body//client_secret" name="uri.var.client_secret" scope="default" type="STRING"/>
<property expression="$body//grant_type" name="uri.var.grant_type" scope="default" type="STRING"/>
<call>
<endpoint key="SFAuth"/>
<source type="body"/>
</call>
<property expression="json-eval($.access_token)" name="uri.var.accessToken" scope="default" type="STRING"/>
<header expression="fn:concat('Bearer ', $ctx:uri.var.accessToken)" name="Authorization" scope="transport"/>
<call>
<endpoint key="SFAnagrafiche"/>
</call>
<property expression="json-eval($.records)" name="uri.var.records" scope="default" type="STRING"/>
<call>
<endpoint key="BEAnagrafiche"/>
<source type="body"/>
<target type="body"/>
</call>
<respond/>
</inSequence>
<outSequence/>
<faultSequence/>
</resource>
</api>该模式一直持续到它调用 BEAnagrafiche 的端点，该端点具有以下 http REST url 到 POST 方法中的 laravel 项目：
http://localhost/webidoo-project/public/api/anagrafiche
这里是 BEAnagrafiche 的 XML：
<?xml version="1.0" encoding="UTF-8"?>
<endpoint name="BEAnagrafiche" xmlns="http://ws.apache.org/ns/synapse">
<http method="post" uri-template="http://localhost/webidoo-project/public/api/anagrafiche">
<suspendOnFailure>
<initialDuration>-1</initialDuration>
<progressionFactor>1.0</progressionFactor>
</suspendOnFailure>
<markForSuspension>
<retriesBeforeSuspension>0</retriesBeforeSuspension>
</markForSuspension>
</http>
<property name="data" value="$ctx:uri.var.records"/>
</endpoint>和后端服务：
public function saveAnagrafiche(Request $request) {
return 'hello';
try {
DB::beginTransaction();
$data = $request->json();
foreach($data as $d) {
if(isset($d['attributes'])) unset($d['attributes']);
$user = new User($d);
$user->save();
}
DB::commit();
return response()->json([
'status' => true,
'message' => 'Anagrafiche salvate correttamente'
], 200);
} catch(\Exception $e) {
DB::rollback();
return response()->json([
'status' => false,
'message' => 'Errore durante il salvataggio delle anagrafiche',
'error' => $e->getMessage()
], 500);
}
}下面还有来自 mi 控制台的最后一条消息：
