我不太确定您的问题是什么,但这是我发送 JSON 的方式(使用您的数据示例)。
Android / JSON 构建:
JSONObject jo = new JSONObject();
jo.put("action", "par_action");
jo.put("par_1", "1");
jo.put("par_2", "2");
jo.put("par_3", "3");
Android / 发送 JSON:
URL url = new URL("http://domaintoreceive.com/pagetoreceive.php");
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url.toURI());
// Prepare JSON to send by setting the entity
httpPost.setEntity(new StringEntity(jo.toString(), "UTF-8"));
// Set up the header types needed to properly transfer JSON
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "application/json");
httpPost.setHeader("Accept-Language", "en-US");
// Execute POST
response = httpClient.execute(httpPost);
PHP/服务器端:
<?php
if (file_get_contents('php://input')) {
// Get the JSON Array
$json = file_get_contents('php://input');
// Lets parse through the JSON Array and get our individual values
// in the form of an array
$parsedJSON = json_decode($json, true);
// Check to verify keys are set then define local variable,
// or handle however you would normally in PHP.
// If it isn't set we can either define a default value
// ('' in this case) or do something else
$action = (isset($parsedJSON['action'])) ? $parsedJSON['action'] : '';
$par_1 = (isset($parsedJSON['par_1'])) ? $parsedJSON['par_1'] : '';
$par_2 = (isset($parsedJSON['par_2'])) ? $parsedJSON['par_2'] : '';
$par_3 = (isset($parsedJSON['par_3'])) ? $parsedJSON['par_3'] : '';
// Or we could just use the array we have as is
$sql = "UPDATE `table` SET
`par_1` = '" . $parsedJSON['par_1'] . "',
`par_2` = '" . $parsedJSON['par_2'] . "',
`par_3` = '" . $parsedJSON['par_3'] . "'
WHERE `action` = '" . $parsedJSON['action'] . "'";
}
