【发布时间】：2017-03-02 01:09:24

【问题描述】：

我有这段代码可以将数据上传到数据库

RequestParams params = new RequestParams();
//prgDialog.show();
params.put("usersJSON", controller.getAllAnswerSheet());
System.out.println("onSuccess getAllAnswerSheet" + controller.numberOfRows("answer_sheet_tbl"));
System.out.println("onSuccess getAllAnswerSheet" + controller.getAllAnswerSheet());
// Make Http call to updatesyncsts.php with JSON parameter which has Sync statuses of Users
client.post("http://127.0.0.1/qna/process/uploadanswersheet.php", params, new AsyncHttpResponseHandler() 

我知道我有数据，因为我在日志中得到了这个

我的问题出在我的uploadanswersheet.php 页面中，我得到Undefined index: usersJSON 这意味着我无法在参数中发送数据。

这是我在uploadanswersheet.php中的代码：

//Get JSON posted by android Application
$json = $_POST["usersJSON"];
//Remove Slashes
$json = json_decode(stripslashes($json), true);
//if (get_magic_quotes_gpc())
//$json = stripslashes($json);
//

【问题讨论】：

请检查 usersJSON 是否正在使用 isset if(isset($_POST['usersJSON'])) echo "true"; else 回声“假”；

"AsyncHttpResponseHandler getting undefined for send params RequestParams android java php" - 这是一句话吗？还是只是单词的集合？

@JagadeshaNH 它没有被发布，因为错误显示未定义。我只是尝试发送一个文本和 php 得到它。不允许在参数中发送 JSONArray 吗？我必须将其转换为字符串然后在 php 中再次转换吗？

@BrownmanRevival 是的，您需要将其转换为字符串，为什么不使用 Apache HTTP 客户端。

因为这种方式是我在搜索解决方案时遇到的第一个方式，所以当我将其转换为字符串时，我会尝试使用 Apache HTTP，它可以工作，您可以提供它作为答案，我会尽快接受 @JagadeshaNH

【参考方案1】：

将 JSON 转换为字符串并发布。并在服务器端将字符串转换回 JSON
