Question

我有基于Spring的休息网络服务来下载文档。我正面临着这项服务的奇怪问题。如果我直接从浏览器地址栏调用此休息服务，我可以下载具有正确字符的文档。但是，如果我从其他客户端/角度应用程序调用相同的休息服务，我会得到一些特殊字符，文档格式不正确。

以下是春假休息服务代码

@RequestMapping(value = "/download", method = RequestMethod.GET)
public ResponseEntity<byte[]> downloadResume(HttpServletRequest request,
        HttpServletResponse response,
        @RequestParam(value = "id") String id)
        throws Exception {


    File file = new File("C:/resume.doc");
    FileInputStream fis = new FileInputStream(file);
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    byte[] buf = new byte[1024];
    try {
        for (int readNum; (readNum = fis.read(buf)) != -1;) {
            bos.write(buf, 0, readNum);
        }
    } catch (IOException ex) {
    }
    byte[] bytes = bos.toByteArray();

    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE);
    httpHeaders.setContentLength(bytes.length);
    httpHeaders.setContentDispositionFormData("attachment", "test");

    return new ResponseEntity(bytes, httpHeaders, HttpStatus.OK);

}

以下是从其他客户端调用下载服务时使用的请求标头参数。

Host: localhost:8080
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:40.0) Gecko/20100101      Firefox/40.0

更新添加了下面的角度代码。但是，来自rest客户端的服务调用也存在同样的问题。

downloadFactory.download(id)
                .then(function(response) {
                    var a = document.createElement("a");
                    document.body.appendChild(a);
                    var blob = new Blob([response.data], {type: "application/octet-stream"});
                    var url = window.URL.createObjectURL(blob);
                    a.href = url;
                    a.download = 'test';;
                    a.click();
                    window.URL.revokeObjectURL(url);

                }, function(error) {                        
                });

特殊字符作为春季下载休息服务的一部分返回
