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
我正在尝试将字符串数组作为 POST 数据传递给 PHP 脚本,但我不确定该怎么做.
I am trying to pass a string array to a PHP script as POST data but am unsure of what to do.
这是我目前执行 PHP 脚本的代码:
Here is my code for executing PHP scripts so far:
我试图传递数组的地方:
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);
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();
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();
}
以及有问题的 PHP 脚本:
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);
?>
有什么想法吗?谢谢!
编辑
我正在尝试以下但仍然没有快乐:
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);
}
这是我所有的错误报告"...
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 !");
}
推荐答案
要在查询字符串中将数组传递给 php,您应该将 []
添加到 identifier 并将每个项目添加为单独的条目,因此这样的事情应该可以工作:
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));
现在,php 端的 $_POST['devices']
将包含一个数组.
now, $_POST['devices']
on php side will contain an array.
