关于私有化部署Appcube访问第三方图片失败，http禁止访问

在https域名下，发起http图片访问请求失败

由于浏览器的安全限制导致的：https安全性高，不允许降级发起http的请求；http安全性低，是允许发起https请求的。平台页面都使用https，无法发起http请求。

针对第三方子系统，如人员通行，车辆通行的抓拍图片，由于部署时未签名认证，都是使用http协议，抓拍的图片如果直接同步到平台，是无法显示的

解决方案

方式一：第三方子系统使用https协议。

方式二：在获取时第三方图片转存OBS或者minio。

如下：先通过GET请求文件流，再通过OBS存入ABC。

// Here's your code.
//
// 图片转存OBS
import * as buffer from 'buffer'
import * as obs from 'objectstorage';
import * as context from 'context';
import * as uuid from 'uuid';
import * as db from 'db'
import * as sys from 'sys';
import * as http from 'http';
import { Logger } from './Common_logger';
import { format } from 'date'

const log = new Logger;
@action.object({ type: 'params' })
export class ParamsInput {
    @action.param({ type: 'String', label: 'alarmType', description: "第三方图片url" })
    url: string;
}

@action.object({ type: 'param' })
export class ParamsOutput {
    @action.param({ type: 'String', label: 'path', description: "图片地址" })
    path: string;
}

@action.object({ type: 'method' })
export const EveryMonth: string = 'EveryMonth';
export class HandleCamerAlarmProcess {

    @action.method({ input: 'ParamsInput', output: 'ParamsOutput' })
    public run(input: ParamsInput): ParamsOutput {
        let out = new ParamsOutput();
        out.path = this.fileUploadcharonTemp(input.url);
        return out;
    }
    private fileUploadcharonTemp(fileUrl: string): any {
        let httpClient = http.newClient();
        try {
            //    例如图片地址为http://192.168.0.1/pictrue,由于图片不能直接通过Http访问，需要转存OBS进行访问。
            let resp = httpClient.get(fileUrl, null);
            log.info("图片流:" + JSON.stringify(resp))
            log.info("图片字节:" + JSON.stringify(resp.body))
            console.error(this.commonDealPic(resp.body), 'resp')
            return this.commonDealPic(resp.body);
        } catch (e) {
            console.error("图片上传错误", e);
            log.error("图片上传错误:" + JSON.stringify(e))
            return null;
        }

    }
    //上传图片
    private upLoadToOBS(data, filename) {
        let res = this.uploadToOBS(data, filename);
        return res && res.fileUrl;
    }

    private commonDealPic(imageBase64) {
        // let imgBinary = buffer.from(imageBase64, buffer.Encoding.Base64).bytes();
        let imgBinary = imageBase64;
        let imgName = uuid.v4() + ".jpg"
        let picFilePath = this.upLoadToOBS(imgBinary, imgName);
        return picFilePath;
    }
    private uploadToOBS(data, fileName) {
        let filePath = this.getUpLoadFilePath(fileName);
        let storageName = sys.getParameter("public_ObsStoreName") || "";
        let obsClient = obs.newClient(obs.StoreType.PROXY, storageName);
        let view = obsClient.uploadObject(filePath, data);
        let fileUrl = '/u-route/baas/sys/v1.1/connectors/objectstorageproxy/' + storageName + '/viewobject?object=' + filePath;
        let res = {
            "view": view,
            "path": filePath,
            "fileUrl": fileUrl
        }
        return res;
    }
    //新增
    private getUpLoadFilePath(fileName) {
        //依据日期建立文件夹，分目录存储
        let objectName = 'lXX97e-upload/smartcampus/personmanagefile/';
        let formatDate = format(new Date(), "yyyyMM", context.getTimeZone());
        let filePath = objectName + EveryMonth + '/' + formatDate + '/' + fileName.substr(fileName.lastIndexOf('/') + 1);
        return filePath;
    }
}

返回地址拼接域名就可以直接在浏览器访问了
