执行结果
正确的返回类似如下:
{
"msg":"OK",
"code":200,
"data":[
{
"msg":"OK",
"code":200,
"dataId":"83c43d81-8cf0-4a21-a367-93a5a07be71a",
"results":[
{
"frames":[
{
"offset":0,
"rate":99.700005,
"label":"porn",
"url":"https://img.alicdn.com/tfs/TB1k_g9l26H8KJjSspmXXb2WXXa-600-600.jpg"
}
],
"rate":99.700005,
"suggestion":"review",
"label":"porn",
"scene":"porn"
},
{
"rate":99.9,
"suggestion":"pass",
"label":"normal",
"scene":"terrorism"
}
],
"taskId":"vo3AaPiZdgQew6So5on$sk$5-1rGm9G"
}
],
