因此，我有这个工作请求，使用HTTPBsaicAuth，需要通过Apigee.我配置了我的Apigee代理与基本Auth检索标题中的用户名和密码，但我仍然得到错误：

{"fault":{"faultstring":"Gateway Timeout","detail":{"errorcode":"messaging.adaptors.http.flow.GatewayTimeout"}}}

下面是没有Apigee通行证的原始请求：

import requests
from requests.auth import HTTPBasicAuth
url = "https://myapi.com/path"
auth =  HTTPBasicAuth("username", "password")
response = requests.get(url, auth=auth, verify=False)

上面的请求工作没有问题。我的新请求，包括Apigee url和apikey在头中：

import requests
from requests.auth import HTTPBasicAuth
url = "https://apigee-proxy.com/basepath/path"
headers = {
    "apikey" : "XXXXXX",
    "username": "username",
    "password": "password"

}
response = requests.get(url, headers=headers, verify=False)

代理设置，非常基本：

<ProxyEndpoint name="default">
    <Description/>
    <FaultRules/>
    <PreFlow name="PreFlow">
        <Request/>
           <Step>
              <Name>Extract-Variables-1</Name>
           </Step>
           <Step>
              <Name>Basic-Authentication-1</Name>
           </Step>
        <Response/>
    </PreFlow>
    <PostFlow name="PostFlow">
        <Request/>
        <Response/>
    </PostFlow>
    <Flows>
    </Flows>
    <HTTPProxyConnection>
        <BasePath>/basepath</BasePath>
        <Properties/>
        <VirtualHost>default</VirtualHost>
    </HTTPProxyConnection>
    <RouteRule name="default">
        <TargetEndpoint>default</TargetEndpoint>
    </RouteRule>
</ProxyEndpoint>

已更新：提取变量-1.xml：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="Extract-Variables-1">
    <Source>request</Source>
    <Header name="username">
        <Pattern ignoreCase="true">{username}</Pattern>
    </Header>
    <Header name="password">
        <Pattern ignoreCase="true">{password}</Pattern>
    </Header>
    <VariablePrefix>auth</VariablePrefix>
    <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
</ExtractVariables>

基本身份验证1策略：

<BasicAuthentication async="false" continueOnError="true" enabled="true" name="Basic-Authentication-1">
    <DisplayName>Basic Authentication-1</DisplayName>
    <Operation>Encode</Operation>
    <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
    <User ref="auth.username"/>
    <Password ref="auth.password"/>
    <AssignTo createNew="false">request.header.Authorization</AssignTo>
</BasicAuthentication>

默认路由规则：

<TargetEndpoint name="default">
    <Description/>
    <FaultRules/>
    <PreFlow name="PreFlow">
        <Request/>
        <Response/>
    </PreFlow>
    <PostFlow name="PostFlow">
        <Request/>
        <Response/>
    </PostFlow>
    <Flows/>
    <HTTPTargetConnection>
        <LoadBalancer>
            <Server name="my_target"/>
        </LoadBalancer>
        <Path>/</Path>
    </HTTPTargetConnection>
</TargetEndpoint>

目标服务器环境变量“my_target”= myapi.com，端口=443
有什么我错过了吗？任何帮助都是感激不尽的。
更新：代理现在包括Extract-Variables-1，我可以看到正在应用身份验证头，但仍超时..：
