我正在从URL下载一个CSV文件,如何设置特定的响应头来下载我的文件?
期望的响应头:
HTTP/1.1 200 OK

Content-Type: application/octet-stream
Content-Length: 340

我的代码:
openFile(url) {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
}
};
xhttp.open("GET",url, true);
xhttp.send();
//window.open(url, '_blank')
}
尝试从URL下载CSV文件。请帮我解决问题。我们如何强制浏览器下载文件?
