使用 POST android 发送 php 数组

Question

我想通过 POST 从 android 发送一个 php 数组到 php 服务器，我有这个代码

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
StringEntity dades = new StringEntity(data);
httppost.setEntity(dades);

// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
return resEntity.getContent();

我认为php数组可能是可以进去的 StringEntity dades = new StringEntity(data); （数据是php数组）。谁能帮帮我？

Answer 1

你可以这样做：

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
nameValuePairs.add(new BasicNameValuePair("colours[]","red"));  
nameValuePairs.add(new BasicNameValuePair("colours[]","white"));  
nameValuePairs.add(new BasicNameValuePair("colours[]","black"));  
nameValuePairs.add(new BasicNameValuePair("colours[]","brown"));  

其中颜色是您的数组标签。只需在数组标记后使用[] 并放置值。例如。如果您的数组标签名称是colour，则像colour[] 一样使用它并将值放入循环中。

Answer 2

public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

try {
    // Add your data
    //you can add all the parameters your php needs in the BasicNameValuePair. 
    //The first parameter refers to the name in the php field for example
    // $id=$_POST['id']; the second parameter is the value.
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("id", "12345"));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}}

上面的代码会发送一个这样的数组： [id=12345, stringdata=AndDev is Cool!]

如果你想要一个双向数组，你应该这样做

Bundle b= new Bundle();
b.putString("id", "12345");
b.putString("stringdata", "Android is Cool");
nameValuePairs.add(new BasicNameValuePair("info", b.toString())); 

这将创建一个包含数组的数组：

[info=Bundle[{id=12345, stringdata=Android is Cool}]]

我希望这是你想要的。
