Question

前端怎么调用打印服务，为什么参考示例，怎么调用都不对？
这是上传的参数：

            },
            "baseLayer": {

您好，您可以参考帮助文档:http://support.supermap.com.cn/DataWarehouse/WebDocHelp/iServer/mergedProjects/SuperMapiServerRESTAPI/root/webprinting/webPrintingJobs.htm进行参数设置，我这边用以下请求参数请求成功，如果您有map-china400这个示例服务，可以尝试直接用文档参数打印测试，

    }

}

您对照检查一下各个参数设置，比如您的"projection"，应该使用"EPSG:3857"的格式，否则无法打印成功，其他参数您需要自行检查。
