imgSecCheck校验一张图片是否含有违法违规内容html
我的小程序只是图片的一些处理识别。固只拿imgSecCheck接口进行代码示例了。
1.在本身的Java后台服务增长接口调用(api.weixin.qq.com不能直接加入小程序安全域名中)
2.在小程序选择图片后优先走违法违规校验。校验经过再走本身的业务代码。java
wx.uploadFile({ url: 图片违法违规校验接口地址, filePath: res.tempFilePaths[0], header: { 'content-type': 'multipart/form-data' }, name: 'file', success: function(checkres) { var checkResult = JSON.parse(checkres.data); console.info(checkResult); if (checkResult.errcode == '0') { //校验没有违法违规进行本身业务代码处理 } else { if (checkResult.errcode == '87014') { wx.hideLoading(); wx.showModal({ content: '存在敏感内容,请更换图片', showCancel: false, confirmText: '明白了' }) } else { wx.hideLoading(); wx.showModal({ content: '其余错误,稍后再试', showCancel: false, confirmText: '明白了' }) } } }
