微信浏览器h5页面开发遇到问题

1.ios不支持window.open(),要创建a链接

let elink = document.createElement('a');

elink.href = baseURL+'/onlineContract/downloadPdf2'+'?custId='+this.$route.query.custId +'&orderId='+localStorage.getItem('orderId')+'&orderType='+localStorage.getItem('orderType');

elink.target = "_parent";

document.body.appendChild(elink);

elink.click();

document.body.removeChild(elink);

2.后台返回图片流形式

Axios.post( //图片流

'/onlineContract/getGraphicCode',

params,

{

responseType:'blob',

emulateJSON:true

}

).then(res =>{

console.log(res)

 this.picSrc = window.URL.createObjectURL(res.data)

})

2.后台返回pdf流形式

Axios.get(  //pdf流

'/onlineContract/downloadPdf2'+'?custId='+this.$route.query.custId +'&orderId='+localStorage.getItem('orderId')+'&orderType='+localStorage.getItem('orderType'),

queryString.stringify(params),

{

responseType:'blob',

emulateJSON:true

}

).then(res =>{

const _res = res.data;

let blob = new Blob([_res], {type: 'application/pdf'});

this.pdfUrl = window.URL.createObjectURL(blob); //创建下载的链接
})
