Java HttpPost到php API

我正试图通过android上的java将一个文件上传到一个使用API的站点

这是我用来发布和获得回复的工具：

    public static HttpResponse upload(String imagePath){
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("www.site.com/api.php");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("type", "file"));
        nameValuePairs.add(new BasicNameValuePair("image", "@" + imagePath));
        nameValuePairs.add(new BasicNameValuePair("thumbsize", "200"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        System.out.println("tryar");
        System.out.println(EntityUtils.toString(httppost.getEntity()));
        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost); 
        return response;

    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;

}

我对网络编程的了解非常有限，但这不等于我在java中所做的吗？

你必须发布文件，而不仅仅是带有

@

符号的文件名。Curl具有定义以@mean file uploads开头的变量的功能，但严格来说，这是一个Curl函数。不要期望Android API有同样的行为

您可以使用

文件

和

多端口

。有一个很好的示例代码

      // post with curl

   $ch = curl_init($postURL);

   $post['type']='file';
   $post['image']='@'.$filename;

   // You can set this to either 100,200,300, or 400 to specify the size of the thumbnail
   $post['thumbsize']="400";   

   curl_setopt($ch, CURLOPT_POST, true);
   curl_setopt($ch, CURLOPT_HEADER, false);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   curl_setopt($ch, CURLOPT_TIMEOUT, 240);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
   curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect: '));

   $result = curl_exec($ch);
   curl_close($ch);

   return $result;
