使用“通过REST服务下载PDF文件”；“内容处置”；Android上的标题

我必须通过具有以下结构的GET请求下载pdf文件：

http://example.example.com/folder/folder/orders/id/folder/download

在postman中，发出请求时，服务器给出的响应如下：

正文：

首先，我尝试用以下方法捕捉身体反应：

HttpEntity httpEntity = response.getEntity();
inputStream = httpEntity.getContent();

然后我尝试创建一个扩展名为pdf的文件，这样我就可以有目的地调用它，并最终通过pdf阅读器应用程序显示它

String extStorageDirectory = Environment.getExternalStorageDirectory()
                .toString();
                File folder = new File(extStorageDirectory, "PDF");
                folder.mkdir();
                File file = new File(folder, "example.pdf");
                try {
                    file.createNewFile();
                    FileUtils.writeStringToFile(file, inputStream);
                } catch (IOException e1) {
                    e1.printStackTrace();
                }  

File fileobject_in_other_method = new File(Environment.getExternalStorageDirectory()+"/PDF/example.pdf");
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    Uri uri = Uri.fromFile(file);
    intent.setDataAndType(uri, "application/pdf");
    startActivity(intent);

没用…：（XD）

我看到一些例子，其中他们谈到用php下载文件并使用“内容处置”标题。但a不明白。我需要在android上完成，请给出一些建议：）

谢谢

最后，这就是我的工作方式：）

你找到解决方案了吗？是的，请原谅我的耽搁，我会发布答案：）

HttpEntity httpEntity = response.getEntity();
inputStream = httpEntity.getContent();

String extStorageDirectory = Environment.getExternalStorageDirectory()
                .toString();
                File folder = new File(extStorageDirectory, "PDF");
                folder.mkdir();
                File file = new File(folder, "example.pdf");
                try {
                    file.createNewFile();
                    FileUtils.writeStringToFile(file, inputStream);
                } catch (IOException e1) {
                    e1.printStackTrace();
                }  

File fileobject_in_other_method = new File(Environment.getExternalStorageDirectory()+"/PDF/example.pdf");
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    Uri uri = Uri.fromFile(file);
    intent.setDataAndType(uri, "application/pdf");
    startActivity(intent);

public String downloadPdf() {
    String responseServer = "";

    try {

        //////PDF folder and file init///////////////////////////

        HttpClient client = HttpClientCustomized.getHttpsClient(new DefaultHttpClient());
       //you can use the default Http Client class instead

        HttpGet get = new HttpGet(sUrl);
        get.addHeader("x-wsse", header);
        HttpResponse response = client.execute(get);
        responseCode = response.getStatusLine().getStatusCode();
        Log.d("responseCode", responseCode + "");
        HttpEntity httpEntity = response.getEntity();
        is = httpEntity.getContent();

        try {

            String typeS = "someFileName".pdf";


directory = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/SomeFolderName/");

    // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            FileOutputStream fi = new FileOutputStream(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/ShippingOrders/" + typeS);

            byte[] buf = new byte[8 * 1024];
            int len = 0;
            while ((len = is.read(buf)) > 0) {
                fi.write(buf, 0, len);
            }

            fi.close();
            is.close();

            System.out.println("Hurra!! : D");
        } catch (IOException e) {
            System.out.println("owww : (" + e.toString());
        }

        responseServer = "TRUE";



    } catch (IOException e) {
        Log.d("IOException", e.toString());
        return "Problems with the server";
    }

    return responseServer;
}
