java - 从 Java 发送 POST 和 FILE 数据

Question

目前，我有一个接受 POST 数据和 FILE ($_POST/$_FILE) 的 PHP 表单。

我如何在 Java 中使用这个表单？ (Android 应用程序)

Answer 1

以下是如何通过 Java(特别是在 Android 中)发送 $_POST。转换为 $_FILE 应该不会太难。这里的一切都是额外的奖励。

public void sendPostData(String url, String text) {

    // Setup a HTTP client, HttpPost (that contains data you wanna send) and
    // a HttpResponse that gonna catch a response.
    DefaultHttpClient postClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url);
    HttpResponse response;

    try {   

       // Make a List. Increase the size as you wish.
       List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

       // Add your form name and a text that belongs to the actual form.
       nameValuePairs.add(new BasicNameValuePair("your_form_name", text));

       // Set the entity of your HttpPost.
       httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

       // Execute your request against the given url and catch the response.
       response = postClient.execute(httpPost);

       // Status code 200 == successfully posted data.
       if(response.getStatusLine().getStatusCode() == 200) {
          // Do something. Maybe you wanna get your response
          // and see what it contains, with HttpEntity class? 
       }

    } catch (Exception e) {
    }

}
