今天突然出现大量的图片安全校验接口发挥大量的 query timeout

具体内容如下：

Error: errCode: 87015 | errMsg: openapi.security.imgSecCheck:fail query timeout, try a content with less size hint: [XPz0Ka06681531]

at callWXOpenAPI (/var/user/node_modules/wx-server-sdk/index.js:2267:31)

at <anonymous>

at process._tickCallback (internal/process/next_tick.js:188:7)

errCode: 87015,

errMsg: 'openapi.security.imgSecCheck:fail query timeout, try a content with less size hint: [XPz0Ka06681531]'
