java - AsyncHttpResponseHandler 未定义发送参数；RequestParams、android、java、php

Question

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它

我的问题出在我的 uploadanswersheet.php 页面上，我得到 Undefined index: usersJSON 意思是我无法发送参数中的数据。

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);
//}

Answer 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
