python - 在调查猴子中包括图像

我正在尝试将图片作为调查问题，它给出了以下错误，

surveymonty.exceptions.SurveyMontyAPIError：{“错误”：{“ docs”：“ https://developer.surveymonkey.com/api/v3/#error-codes”，“消息”：“无法验证字段“标题”列表架构：字段中不允许使用“属性”未定义的其他属性'_data'“，” id“：” 1002“，” name“：”错误请求“，” http_status_code“：400}}

我正在使用以下JSON代码，

payload ={
    "headings":
    [
            {
            "heading": "This is a monkey",
            "image":    {
                "img_url": "https://raw.githubusercontent.com/SurveyMonkey/public_api_docs/master/images/presentation.png"
                    }
             }
        ],
    "position": 4,
    "family": "presentation",
    "subtype": "descriptive_text"
    }

请帮助！

最佳答案

您可能正在寻找image子类型，有效负载应更像：

{
    "headings": [{
        "heading": "This is a monkey",
        "image": {
            "url": "https://raw.githubusercontent.com/SurveyMonkey/public_api_docs/master/images/presentation.png"
        }
    }],
    "position": 4,
    "family": "presentation",
    "subtype": "image"
}
