如何将名称 - 值对附加到MultiPart POST请求?

此示例适用于其中一个,但不适用于两者:

public void postData() {  
    //http://www.softwarepassion.com/android-series-get-post-and-multipart-post-requests/
    File f = new File(filename);
    try {
             HttpClient client = new DefaultHttpClient();  
             String postURL = "http://url.com/script.php";


             HttpPost post = new HttpPost(postURL); 
    //         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);  
      //       nameValuePairs.add(new BasicNameValuePair("project", projectName));  
        //     nameValuePairs.add(new BasicNameValuePair("name", imageName));  
          //   post.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

             FileBody bin = new FileBody(f);
             MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);  
             reqEntity.addPart("file", bin);

             post.setEntity(reqEntity); 

             HttpResponse response = client.execute(post);  
             HttpEntity resEntity = response.getEntity();  
             if (resEntity != null) {    
                       Log.i("RESPONSE",EntityUtils.toString(resEntity));
                 }
    } catch (Exception e) {
        e.printStackTrace();
    }


}

似乎当我调用setEntity()时,前一个实体被覆盖 - 所以我可以拥有名称值对或文件数据,但不能同时使用两者。你知道如何整合它们,所以我可以在上传中使用URL参数吗?只需将它们附加到POST URL就不起作用了。

我也试过

  post.addHeader("project", projectName);
  post.addHeader("name", imageName);                 

但这似乎也没有用。

感谢。

这似乎可以解决问题:

             reqEntity.addPart("project", new StringBody(projectName));
             reqEntity.addPart("name", new StringBody(imageName));
