downloadfile 图片请求 但是为什么返回的是text/html格式?
Page({
data: {
header: {},
verifycode: '',
img: '',
},
onLoad: function() {
var _this = this;
var str = 'http://jwgl.thxy.edu.cn/yzm?d' + new Date().getTime();
console.log('时间戳为：',new Date().getTime());
wx.downloadFile({
url: str,
success: function(res) {
console.log(res);
_this.setData({
header: {
'cookie': res.header['Set-Cookie'],
'content-type': 'application/x-www-form-urlencoded;charset=UTF-8',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36 Edg/96.0.1054.29'
}
});
_this.setData({
img: res.tempFilePath
})
}
})
},
