var xhr =
new XMLHttpRequest()
// 配置的代理，解决跨域问题
xhr.open('GET', url.replace('http://xxx.com', '/img'),
true)
xhr.responseType = 'blob'
xhr.onload =
function () {
if (xhr.status === 200
) {
var reader =
new FileReader()
reader.readAsDataURL(xhr.response)
reader.onloadend =
function () {
var base64data =
reader.result.replace(/^data:image\/(png|jpg);base64,/, ""
)
}
}
}
xhr.send()
总的来说就是将url先转blob,然后将blob转成base64
