如何將標題添加到多部分請求？

Question

我有一個多部分的請求，它有3個部分，每個部分包含它自己的主體和標題，所以我想要的是在其中一個部分添加自定義標題。我試圖用retrofit和okhttp來構建請求，但是他們沒有提供這樣做的選項。有任何想法嗎？

嘗試以下代碼：

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; 

}
