Azure API 管理策略 - 使用条件语句转换正文

Question

我正在使用 C# 语法来转换有效负载主体 使用条件语句来转换主体，如果可能的话，我想使用条件语句来转换有效负载主体的一个键。下面的代码显示了该场景的更多说明。
我尝试实现我想要实现的目标，但出现错误。不确定这是否只是我的语法，或者将逻辑放在那里是否有意义。

如果这是有效负载:

{
    "dependentee_name": "Steve",
    "dependentee_last_name": "Rogers",
    "dependentee_comment" : "This is test",
    "dependentee_relationship_primary" : "Parent",
    "dependentee_relationship_secondary" : "null",
    "insurer_name": "Steve",
    "insurer_last_name": "Rogers",
    "insurer_comment" : "This is test",
    "extra_info": "This is comments"
}

如有效负载中所示，有一个关键 dependentee_relationship_primary ，其值为 Parent，因此预期的转换主体如下:

    {
      "dependentee_info": {
        "name": "Steve",
        "last_name": "Rogers"
    
      },
      "insurer_info": {
        "i_name": "Tony",
        "i_last_name": "Stark"
      },
      "extra_info" : "This is comments",
      "relationship_type" : "Parent"
    }

如果这是有效负载:

    {
        "dependentee_name": "Steve",
        "dependentee_last_name": "Rogers",
        "dependentee_comment" : "This is test",
        "dependentee_relationship_primary" : "null",
        "dependentee_relationship_secondary" : "Uncle",
        "insurer_name": "Steve",
        "insurer_last_name": "Rogers",
        "insurer_comment" : "This is test",
        "extra_info": "This is comments"
    }

如有效负载所示，有一个关键 dependentee_relationship_secondaru ，其值为 Uncle，因此预期的转换主体如下:

    {
      "dependentee_info": {
        "name": "Steve",
        "last_name": "Rogers"
    
      },
      "insurer_info": {
        "i_name": "Tony",
        "i_last_name": "Stark"
      },
      "extra_info" : "This is comments",
      "relationship_type" : "Uncle"
    }

到目前为止我已经尝试过该代码，但遇到了错误

Azure API Management Policies - Using conditional statements - For Payloads 的重复项

首先，最好修复长期存在的拼写错误问题，例如我已经为您修复的 dependetee:

Azure API Management (Policies)

你必须检查是否

• 主体有一个 child dependentee_relationship_primary
• 属性dependentee_relationship_primary不为null
• 属性dependentee_relationship_primary不是空字符串

if (body.ContainsKey("dependentee_relationship_primary") && body["dependentee_relationship_primary"].Type != JTokenType.Null && !string.IsNullOrEmpty(body["dependentee_relationship_primary"].Value<string>()))
{
   transformedBody["relationship_type"] = body["dependentee_relationship_primary"];
} 

完整的政策:

<policies>
    <inbound>
        <base />
        <return-response>
            <set-status code="200" reason="ok" />
            <set-header name="Content-Type" exists-action="override">
                <value>application/json</value>
            </set-header>
            <set-body>@{
                var body = context.Request.Body.As<JObject>(true);

                var transformedBody = new JObject();
                transformedBody["extra_info"] = body["extra_info"];
                
                var dependentee= new JObject();
                dependentee["name"] = body["dependtee_name"];
                dependentee["lastName"] = body["depdentee_last_name"];
                transformedBody["dependtee_info"] = dependentee;

                var insurer_info = new JObject();
                insurer_info["i_name"] = body["insurer_name"];
                insurer_info["i_last_name"] = body["insurer_last_name"];
                transformedBody["insurer_info"] = insurer_info;

                if (body.ContainsKey("dependentee_relationship_primary") && body["dependentee_relationship_primary"].Type != JTokenType.Null && !string.IsNullOrEmpty(body["dependentee_relationship_primary"].Value<string>()))
                {
                    transformedBody["relationship_type"] = body["dependentee_relationship_primary"];
                } 
                else if (body.ContainsKey("dependentee_relationship_secondary") && body["dependentee_relationship_secondary"].Type != JTokenType.Null && !string.IsNullOrEmpty(body["dependentee_relationship_secondary"].Value<string>()))
                {
                    transformedBody["relationship_type"] = body["adultrelationship"];
                }

                return transformedBody.ToString();               
            }</set-body>
        </return-response>
    </inbound>
    <backend>
        <base />
    </backend>
    <outbound>
        <base />
    </outbound>
    <on-error>
        <base />
    </on-error>
</policies>

结果:

顺便说一句:
你的条件没有意义:没有定义adultrelationship。
