axios
.get(\'/captcha\', {
params: param,
responseType: \'arraybuffer\'
})
.then(response => {
return \'data:image/png;base64,\' + btoa(
new Uint8Array(response.data)
.reduce((data, byte) => data + String.fromCharCode(byte), \'\')
);
}).then(data => {
...
})
这样写即可,
如果请求中没有额外的头信息,只需要加img标签src=请求接口地址即可
