如何将标头添加到多部分请求？

Question

我有一个包含 3 个部分的多部分请求，每个部分都包含自己的正文和标头，所以我想要在其中一个部分上添加一个自定义标头。我试图用改造和 okhttp 来构建请求，但他们没有提供这样做的选项。有什么想法吗？

编辑：这是基于question

试试下面的代码：

public HttpResponse multiPartRequest(String url, String token, File file) {

client = new DefaultHttpClient();

HttpPost request = new HttpPost(url);

HttpResponse response = null;

DRPContentForUpload content = new DRPContentForUpload(file);
String jsonObject = DRPJSONConverter.toJson(content);
String BOUNDARY= "--eriksboundry--";

request.setHeader("Content-Type", "multipart/form-data; boundary="+BOUNDARY);
request.addHeader("X-AUTHORIZATION",token);
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE,BOUNDARY,Charset.defaultCharset());
try {


    entity.addPart("file01", new StringBody(jsonObject));

    entity.addPart("file01", new FileBody(file));

    request.addHeader("Accept-Encoding", "gzip, deflate");

} catch (UnsupportedEncodingException e) {
    Log.v("encoding exception","E::: "+e);
    e.printStackTrace();
}
request.setHeader("Accept", "application/json");
request.setHeader("Content-Type", "multipart/form-data; boundary="+BOUNDARY);
request.setEntity(entity);

try {




    response = client.execute(request);



} catch (ClientProtocolException e) {

    e.printStackTrace();
} catch (IOException e) {

    e.printStackTrace();
}


return response;

}
