环境:微服务请求后端,返回二进制流文件(图片) application/octet-stream,在ng2/ng4前端进行展示。遇到情况:1.尝试使用URL.createObjectURL(response)后添加 bypassSecurityTrustUrl。依旧提示unsafe//html<img [src]="imgUrl">//tsgetImg() { const host = 'http://localhost:8083/'; const url2 = host + 'api/bpm-extend/repository/process-definitions/myEclipseDemo:7:227504/diagram-resource'; let firstheaders = new Headers(); firstheaders.append('Content-Type', 'image/png'); const opts: RequestOptionsArgs = { headers: firstheaders, responseType: 3 } this.http.get(url2, opts).map((resp) => resp.json()).catch((err) => {throw err;}) .subscribe((val) => { this.imgUrl = this.sanitizer.bypassSecurityTrustUrl( window.URL.createObjectURL(val) ); }) }问题:请问如何解决此情况?或者是的方法错了,那有没有其他解决方案?
