我不知道爲什麼我無法從我的PHP代碼中獲得正確的響應。對於我的PHP代碼,它非常簡單。它應該只是返回POST參數。但在我的Android項目中,它爲所有參數返回null。我試圖在我的iOS項目中測試PHP代碼。一切都很完美。它返回["target": zh, "arrayString": <__NSSingleObjectArrayI 0x6000000192a0>(hello world), "source": en]
因此,我想也許我的Android項目有一些問題,然後我嘗試創建一個新項目並再次執行,但仍然遇到同樣的問題。以下是我的新Android項目的步驟。JsonObjectRequest - 無法發送參數

PHP代碼
<?php
$source = $_POST['source'];
$target = $_POST['target'];
$arrayString = $_POST['stringArray'];
echo json_encode(array('source'=>$source,'target'=>$target,'arrayString'=>$arrayString));
?>
嘗試'$ postArray = json_decode(的file_get_contents( 'PHP://輸入'),TRUE);',然後'$源= $ postArray [ '源']'等上。或者最好在第一行之後執行'var_dump($ postArray)'。 – Jeff
一旦我使用了'''$ postArray = json_decode(file_get_contents('php:// input'),true);,那麼$ source = $ postArray ['source']'''我可以得到正確的結果。非常感謝 –
然後我會添加這個答案!下降自由接受它... – Jeff
