对 php 的发布请求中缺少 json 数组

Question

我正在尝试将 json 对象从 Android 设备发送到 PHP 以将其插入数据库，但服务器找不到它。我做错了什么？谢谢。

脚本在 isset 检查中失败。

PHP 脚本：

    <?php

$json_array = json_decode($_POST['messages']) -> messages;

if(isset($json_array))
{
    //connect to database and do insertions.
} else
{
    echo "Not found array with messages in POST request\n";
}

发布请求包含：

{"messages":[{"message":"Hello. Test from ukraine","id":1,"from_sender":"1111-111-1111","box":"2","type":"sms"}]}

它是这样形成的：

HttpClient httpClient = new DefaultHttpClient();

            try {
                HttpPost httpPost = new HttpPost(BASE_URL + "/josyko.php");
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                nameValuePairs.add(new BasicNameValuePair("messages", request.toString()));
                httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                HttpResponse httpResponse = httpClient.execute(httpPost);
                result = EntityUtils.toString(httpResponse.getEntity());
            } catch (IOException e) {
                e.printStackTrace();
            }

Answer 1

您可以使用：http://php.net/manual/en/reserved.variables.httprawpostdata.php

$json_array = json_decode($HTTP_RAW_POST_DATA) -> messages;

或者更好的解决方案：

file_get_contents('php://input'); // instead of $HTTP_RAW_POST_DATA
