使用 bicep 将 xml 策略部署到 apim

Answer 1

经验教训 - 多注意 chatgpt 输出的内容！

主要问题是 C# 代码块的语法。这是工作方针：

<policies>
    <inbound>
    <base />
    <choose>
        <when condition="@(!context.Variables.ContainsKey("cachedAccessToken") || DateTime.UtcNow >= (DateTime)context.Variables["tokenExpiry"])">
            <set-backend-service id="apim-generated-policy" backend-id="func-amx-api-dev-001" />
            <send-request mode="new" response-variable-name="tokenResponse" timeout="20" ignore-error="false">
                <set-url>{{baseurl}}.azurewebsites.net/token</set-url>
                <set-method>POST</set-method>
                <set-header name="Content-Type" exists-action="override">
                    <value>application/x-www-form-urlencoded</value>
                </set-header>
                <set-body>@("grant_type=password&username={{user}}&password={{AmxPassword}}")</set-body>
            </send-request>
            <set-variable name="cachedAccessToken" value="@((String)((IResponse)context.Variables["jwt"]).Body.As<JObject>()["access_token"])" />
            <set-variable name="tokenExpiry" value="@((String)((IResponse)context.Variables["jwt"]).Body.As<JObject>()["expires_in"])" />
            <cache-store-value key="cachedAccessToken" value="@((String)context.Variables["cachedAccessToken"])" duration="3600" caching-type="internal" />
            <cache-store-value key="tokenExpiry" value="@((String)context.Variables["tokenExpiry"])" duration="3600" caching-type="internal" />
        </when>
        <otherwise>
            <cache-lookup-value key="cachedAccessToken" variable-name="cachedAccessToken" />
            <cache-lookup-value key="tokenExpiry" variable-name="tokenExpiry" />
        </otherwise>
    </choose>
    <set-header name="Authorization" exists-action="override">
        <value>@{
                return $"Bearer {(String)context.Variables["cachedAccessToken"]}";
            }</value>
    </set-header>
    </inbound>
    <backend>
        <base />
    </backend>
    <outbound>
        <base />
    </outbound>
    <on-error>
        <base />
    </on-error>
</policies>

我还将策略移动到一个单独的文件，并使用以下二头肌在 apim 操作级别部署：

resource apiPolicy 'Microsoft.ApiManagement/service/apis/operations/policies@2022-09-01-preview' = {
    name: '${apimName}/amxapi_v1_0_0/entity/policy'
    properties: {
        value: loadTextContent('./createEntityPolicy.xml')
    }
}
