pdf标题中的奇怪字符

Question

我有一个应用程序，我在其中显示我之前创建的pdf：

服务器端

public ResponseEntity<InputStreamResource> 
getMsgboxSummaryPdf(HttpServletRequest request, HttpServletResponse response){...

InputStream stream = new ByteArrayInputStream(report.getBytes(StandardCharsets.UTF_8)); 

response = new ResponseEntity<InputStreamResource>(new InputStreamResource(stream),
                new ReportsService().createPdfHeader(report), HttpStatus.OK);
return response;
}

/**
 * Create PDF header.
 *
 * @param report
 *            report to write PDF
 * @return PDF header
 */
public HttpHeaders createPdfHeader(String report) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.parseMediaType("application/pdf"));
    headers.add("Access-Control-Allow-Origin", "*");
    headers.add("Access-Control-Allow-Methods", "GET, POST, PUT");
    headers.add("Access-Control-Allow-Headers", "Content-Type");
    headers.add("Content-Disposition", "filename=sysparamspdf");
    headers.add("Cache-Control", "no-cache, no-store, must-revalidate");
    headers.add("Pragma", "no-cache");
    headers.add("Expires", "0");
    headers.setContentLength(report.getBytes(StandardCharsets.UTF_8).length);
    return headers;
}

客户端

 success :  function(response) {
            var data = this.toBinaryString(response.responseText);
            data = "data:application/pdf;base64,"+btoa(data);
            var window = this.createWindowPdf(data)
 ...

  toBinaryString: function(data) {
    var ret = [];
    var len = data.length;
    var byte;
    for (var i = 0; i < len; i++) {
        byte=( data.charCodeAt(i) & 0xFF )>>> 0;
        ret.push(String.fromCharCode(byte) );
    }
    return ret.join('');
},

结果 的问题

该报告工作正常，但我不知道如何更改pdfs查看器标题中出现的奇怪字符。

有人能给我一个想法吗？

提前致谢。

Answer 1

尝试通过标头设置文件名：

{{1}}

然后将responseHeaders设置为responseEntity。
