Php 从Delphi InternetReadFile读取字符串

我正在向我的PHP页面发送一个JSON查询

因为我在服务器上的JSON部分遇到了问题（我是JSON新手）

我决定让服务器把它发回，这样我就可以看到它了

这是我发送给它的JSON文本，因此希望它能发送回我（是的，它包含伪数据）：

我已经确认这是发送到服务器的内容，上传的数据中没有#0

以下是接收并发送回客户端的代码：

<?

if (file_get_contents('php://input')) {
    $json = file_get_contents('php://input');
    echo $json;

$parsedJSON = json_decode($json);
// (error here)  echo $parsedJSON->city;
}

?>

从服务器接收回来后，似乎编码不明确。看到unicode编码从服务器上恢复，我不会感到惊讶，但我不知道该如何处理这个文本

卡布弗包含：

你认为我做错了什么

谢谢大家!

php://input

将为您提供传输到服务器的整个数据包，而不仅仅是内容。这也将包括标题

我不是Delphi专家，但我猜您发送的JSON并不像您想象的那样

据我所知，这种情况不应该发生，但我还是要提到：如果使用压缩，您得到的数据可能会被归档，但正如我所提到的，情况不应该是这样

---

除非你得到一个好的标题+内容数据，否则这意味着发送了错误的数据。

123，0是{，34，0是"在UTF-16中，问题是，缓冲区开头的10是什么？为什么要发送UTF-16而不是UTF-8？但是缓冲区的结尾不是文本。坦率地说，如果你想取得进展，你需要根据第一原则确定你要发送的内容。不要尝试使用试错法来反转它。确保你理解“明白你在传输什么。@DavidHeffernan，谢谢你在堆栈溢出方面所做的所有工作；一些非常好的答案，先生。我把它改为使用TidHttp.Post（url，stream）这帮了我很大的忙。现在不是没有文档工作，而是大文档坏了。我可能有几个星期没有时间再讨论这个问题了。哦，很高兴知道。我是JSON新手。我需要暂时离开这个。谢谢你的帮助！
