Description
应该是XMLHttpRequest的问题，使用fetch函数可以下载，可惜也不维护了
download: function (url, data, method = "POST") { var xhr = new XMLHttpRequest(); xhr.open(method, url, true); // 也可以使用POST方式，根据接口 xhr.responseType = "blob"; // 返回类型blob xhr.setRequestHeader('content-type', 'application/json'); xhr.setRequestHeader('Authorization', 'Bearer ' + localStorageFuncs.get("wtmtoken")); xhr.onload = function () { if (this.status === 200) { var fname = this.getResponseHeader("content-disposition"); var filename = ""; if (/filename\*=UTF-8''(.*?)($|;|\s)/.test(fname)) { filename = RegExp.$1; } else if (/filename=(.*?)($|;|\s)/.test(fname)) { filename = RegExp.$1; } filename = decodeURI(filename); var blob = this.response; var reader = new FileReader(); reader.readAsDataURL(blob); reader.onload = function (e) { var a = document.createElement('a'); a.download = filename; a.href = e.target.result; document.body.append(a); a.click(); a.remove(); } } }; // 发送ajax请求 xhr.send(data) }
