通过Post Android将数据发送到PHP

Question

因此，我正在尝试通过Android中的Post将消息发送到PHP，这是Android Java函数：

 //enviando para o backend
private void SendtoPHP(String reg) throws IOException {


    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://bubbledev.com.br/gcm/getdevice.php");

    try{
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("regid", "" + reg ));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);


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

}

PHP：

<?php       
include 'conecta.php';
$device_token  = urldecode($_POST['regid']);    
$sql = "INSERT INTO corposa.deviceandroid"
              . " (id,device_token)"
              . " VALUES (NULL,'$device_token')";
mysqli_query($con,$sql);    

？>

PHP很好，我已经在另一个Post上对其进行了测试并可以工作，但是当Android函数尝试$ device_token时，不要接收任何值，并且SQL在表中保存带有ID的“”

除了ResponseHandler之外，我使用与您的代码相似的代码。 这个对我有用。

HttpClient Client = new DefaultHttpClient();

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", sID));
nameValuePairs.add(new BasicNameValuePair("etc", sETC));

try {           

    String SetServerString = "";

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://your-url.com/script.php");
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    ResponseHandler<String> responseHandler = new BasicResponseHandler();

    SetServerString = httpclient.execute(httppost, responseHandler);                

}  catch(Exception ex) {
    // failed
}

我敢肯定有更好的方法可以做到这一点，但这是我通常处理来自Android的发布请求的方式：

<?php
{
    $input = json_encode(file_get_contents("php://input"));

    $deviceToken = $input->regId;
    mysqli_query($connection, "INSERT INTO corposa.deviceandroid (`id`, `device_token`) VALUES(NULL, '" . mysqli_real_escape_string($deviceToken) . "')";
}

另外，由于您使用的是POST而不是GET，因此传递到服务器的数据不是经过url编码的，因此这里不需要urldecode。

代码似乎还可以，只有“奇怪”的东西是：

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

因为您仅将一个BasicNameValuePair添加到列表中。 也许是问题所在...？

我在当前项目中使用了此代码，希望它也对您有用

  Map<String, String> kvPairs = new HashMap<String, String>();
    kvPairs.put("regid", reg);
    HttpClient httpclient = this.getNewHttpClient();
    HttpPost httppost = new HttpPost("http://bubbledev.com.br/gcm/getdevice.php");
    if (kvPairs != null && kvPairs.isEmpty() == false) {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(kvPairs.size());
        String k, v;
        Iterator<String> itKeys = kvPairs.keySet().iterator();
        while (itKeys.hasNext()) {
            k = itKeys.next();
            v = kvPairs.get(k);
            nameValuePairs.add(new BasicNameValuePair(k, v));
        }
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
    }
    HttpResponse response;
    response = httpclient.execute(httppost);
    String responseString = EntityUtils.toString(response.getEntity());

您的课程中也需要此方法

public static HttpClient getNewHttpClient() {
    try {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(null, null);

        SSLSocketFactory sf = new RecorridoSSL(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", sf, 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        return new DefaultHttpClient(ccm, params);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}

希望我不要忘记任何事情，以其他方式告诉我

伙计们，错误是我的PHP

$device_token  = urldecode($_POST['regid']); 

这个urldecode弄乱了我的代码哈哈

感谢所有帮助
