将字符串数组作为POST传递给PHP [英] Passing String array to PHP as POST
问题描述
我试图将一个字符串数组作为POST数据传递给PHP脚本，但不知道该怎么做。
这是执行PHP脚本的代码远：
在哪里试图传递数组：
nameValuePairs.add（new BasicNameValuePair（message，message））;
String [] devices = {device1，device2，device3};
nameValuePairs.add（新BasicNameValuePair（ 装置，装置））; //< - 不能传递字符串[]至BasicNameValuePair
callPHPScript（ notify_devices，namevaluepairs中）; b
$ b 调用PHP脚本： > public String callPHPScript（String scriptName，List< NameValuePair> parameters）{
HttpClient client = new DefaultHttpClient（）;
HttpPost post = new HttpPost（http：// localhost /+ scriptName）;
String line =;
StringBuilder stringBuilder = new StringBuilder（）;
尝试{
post.setEntity（new UrlEncodedFormEntity（parameters））;
HttpResponse response = client.execute（post）;
if（response.getStatusLine（）。getStatusCode（）！= 200）
{
System.out.println（DB：Error executed error！）;
}
else {
BufferedReader rd = new BufferedReader（new InputStreamReader（
response.getEntity（）。getContent（）））;
line =; （（line = rd.readLine（））！= null）{
stringBuilder.append（line）;
while
}
}
} catch（IOException e）{
e.printStackTrace（）;
}
System.out.println（DB：Result：+ stringBuilder.toString（））;
return stringBuilder.toString（）;
}
以及PHP脚本：
<？php
include（'tools.php'）;
//替换为Google API中真正的BROWSER API密钥
$ apiKey =123456;
//替换为真正的客户端注册ID
$ registrationIDs = array（$ _ POST [devices]）; < - 我想将数组传递给脚本
//要发送的消息
$ message = $ _POST ['message'];
//设置POST变量
$ url ='https://android.googleapis.com/gcm/send';
$ fields = array（
'registration_ids'=> $ registrationIDs，
'data'=> array（message=> $ message），
）;
$ headers = array（
'Authorization：key ='。$ apiKey，
'Content-Type：application / json'
）;
//打开连接
$ ch = curl_init（）;
//设置网址，POST变量的数量，POST数据
curl_setopt（$ ch，CURLOPT_URL，$ url）;
curl_setopt（$ ch，CURLOPT_POST，true）;
curl_setopt（$ ch，CURLOPT_HTTPHEADER，$ headers）;
curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）;
curl_setopt（$ ch，CURLOPT_POSTFIELDS，json_encode（$ fields））;
//执行后
$结果= curl_exec（$ ch）;
//关闭连接
curl_close（$ ch）;
print_as_json（$ result）;
？>
有什么想法？感谢！
编辑
public void notifyDevices（消息消息）{
List< NameValuePair> nameValuePairs = new ArrayList< NameValuePair>（）;
列表< String> deviceIDsList = new ArrayList< String>（）;
String [] deviceIDArray;
//获取设备以通知
List< JSONDeviceProfile> deviceList = getDevicesToNotify（）; （JSONDeviceProfile device：deviceList）{
deviceIDsList.add（device.getDeviceId（））;
}
//设备ID数组
deviceIDArray = deviceIDsList.toArray（new String [deviceIDsList.size（）]）;
for（String deviceID：deviceIDArray）{
nameValuePairs.add（new BasicNameValuePair（devices []，deviceID））;
$ b $ //调用脚本
callPHPScript（GCM.php，nameValuePairs）;
}
这是所有错误报告我有...
HttpResponse response = client.execute（post）;
if（response.getStatusLine（）。getStatusCode（）！= 200）
{
System.out.println（DB：Error executed error！）;
在查询字符串中，您应该为标识符添加 [] ，并将每个项目添加为单独的条目，所以类似这样的内容应该可以工作：
nameValuePairs.add（new BasicNameValuePair（devices []，device1））;
nameValuePairs.add（new BasicNameValuePair（devices []，device2））;
nameValuePairs.add（new BasicNameValuePair（devices []，device3））;
现在， $ _ POST ['devices'] 在PHP方面将包含一个数组。
I am trying to pass a string array to a PHP script as POST data but am unsure of what to do.
Here is my code for executing PHP scripts so far:
Where I am trying to pass the array:
nameValuePairs.add(new BasicNameValuePair("message",message));
String [] devices = {device1,device2,device3};
nameValuePairs.add(new BasicNameValuePair("devices", devices));// <-- Can't pass String[] to BasicNameValuePair
callPHPScript("notify_devices", nameValuePairs);
Call PHP script:
public String callPHPScript(String scriptName, List<NameValuePair> parameters) {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://localhost/" + scriptName);
String line = "";
StringBuilder stringBuilder = new StringBuilder();
try {
post.setEntity(new UrlEncodedFormEntity(parameters));
HttpResponse response = client.execute(post);
if (response.getStatusLine().getStatusCode() != 200)
{
System.out.println("DB: Error executing script !");
}
else {
BufferedReader rd = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()));
line = "";
while ((line = rd.readLine()) != null) {
stringBuilder.append(line);
}
}
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("DB: Result: " + stringBuilder.toString());
return stringBuilder.toString();
}
And the PHP script in question:
<?php
include('tools.php');
// Replace with real BROWSER API key from Google APIs
$apiKey = "123456";
// Replace with real client registration IDs
$registrationIDs = array($_POST[devices]); <-- Where I want to pass array to script
// Message to be sent
$message = $_POST['message'];
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registrationIDs,
'data' => array( "message" => $message ),
);
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
// Execute post
$result = curl_exec($ch);
// Close connection
curl_close($ch);
print_as_json($result);
?>
Any ideas? Thanks !
Edit
I am trying the following but still no joy:
public void notifyDevices(Message message) {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
List<String> deviceIDsList = new ArrayList<String>();
String [] deviceIDArray;
//Get devices to notify
List<JSONDeviceProfile> deviceList = getDevicesToNotify();
for(JSONDeviceProfile device : deviceList) {
deviceIDsList.add(device.getDeviceId());
}
//Array of device IDs
deviceIDArray = deviceIDsList.toArray(new String[deviceIDsList.size()]);
for(String deviceID : deviceIDArray) {
nameValuePairs.add(new BasicNameValuePair("devices[]", deviceID));
}
//Call script
callPHPScript("GCM.php", nameValuePairs);
}
This is all the "Error reporting" I have...
HttpResponse response = client.execute(post);
if (response.getStatusLine().getStatusCode() != 200)
{
System.out.println("DB: Error executing script !");
}
To pass an array to php in query string, you should add [] to identifier and add every item as separate entry, so something like this should work:
nameValuePairs.add(new BasicNameValuePair("devices[]", device1));
nameValuePairs.add(new BasicNameValuePair("devices[]", device2));
nameValuePairs.add(new BasicNameValuePair("devices[]", device3));
now, $_POST['devices'] on php side will contain an array.
