添加全局state,存储Meta内容
发布于 6 年前 作者 shenjuan 11233 次浏览 来自 问答

现在是只能识别一个图片,跳转到一个页面,我这边的需求是:识别12个图片,识别成功之后,可以跳转到对应识别图的页面,我现在遇到的问题是:识别图的Token值是唯一的,图片不会区分,该怎么区分图片,怎么在小程序里识别的mate该怎么保存。希望可以得到帮助谢谢。以下是代码片段:

//pages/recognition/recognition.js

//import upng from ‘…/…/UPNG.js’

Page({

data: {

height: ‘500’,

width: ‘20’,

status: false,

scanStatus: ‘none’,

color: ’ #6495ED’,

msg: “”,

src: ‘’,

isShow:true , //花边

isperson:true//人

},

onLoad: function (options) {

this.ctx = wx.createCameraContext();

wx.getSystemInfo({

success: res => {

this.setData({ height: res.windowHeight *0.8, width: res.windowWidth});

}

});

},

stopScan: function () {

this.setData({ scanStatus: ‘none’, msg: ‘111111’});

},

onShow: function () {

this.setData({

msg: ‘点击识别名片’,

isShow: true, //花边

isperson: false

});

},

error: function (e) {

this.setData({ msg: ‘请重新点击识别’ });

},

urlTobase64(imgPath) {

let that = this;

wx.getFileSystemManager().readFile({

filePath: imgPath, //选择图片返回的相对路径

encoding: ‘base64’, //编码格式

success: res => { //成功的回调

console.log(‘data:image/png;base64,’ + res.data)

that.searchPhotp(res.data)

}

})

},

searchPhotp: function(imageBase64) {

let that = this;

wx.request({

url: https://cn1-crs.easyar.com:8443/search,

data: {

image: imageBase64

},

header: {

‘Authorization’: ‘g7BVXzTjfuuM3RNg3KOSLcRzwx8chRtNUo+79iEFkuEudgZswH9a6c8GnKY1btGFoq/O8x72TrnO/tr27+MIiA==’,

‘content-type’: ‘application/json’ // 默认值

},

method: ‘POST’,

success(res) {

if (res.data.statusCode == 0) {

console.log(“成功”);

that.setData({

msg: ‘识别成功’,

isShow:false

});

setTimeout(() => {

console.info(‘go to webar’);

that.setData({

msg: ‘’,

//出效果

isperson:true

});

}, 500);

setTimeout(() => {

console.info(‘go to webar’);

wx.navigateTo({

url: ‘…/show/show’

});

}, 5000);

} else {

that.status = false;

that.setData({ msg: ‘识别失败,请重试’});

}

},

fail(err) {

console.log(err)

that.status = false;

that.setData({ msg: ‘识别失败,请重试’});

}

})

},

takePhoto: function (e) {

//if (this.status) return;

console.log(11111)

this.status = true;

this.ctx.takePhoto({

quality: ‘low’,

success: res => {

this.setData({ msg: ‘识别中…’, src: res.tempImagePath});

this.urlTobase64(res.tempImagePath);

},

fail: err => {

this.stopScan();

this.setData({ msg: ‘未识别到目标’ });

}

});

}

})
