Question

我正在向我的PHP页面发送JSON查询。

因为我在服务器上遇到了JSON部分的问题（我是JSON的新手）。

我决定让服务器把它发回去，这样我才能看到它。

这是我发送给它的JSON文本，因此希望它发回给我（是的，它包含虚拟数据）：

{"propertyType":"Detached","price":"edtPrice","bedrooms":"2","bathrooms":"2","squareFeet":"1200","address":"edtAddr","city":"edtCity","postal":"edtPostal","agentPhone":"edtAgent","agentEMail":"edtEMail","agentName":"edtAgent","agentCompany":"edtCompany","Pictures":[]}

我已经确认这是发送到服务器的内容，并且在上传的数据中没有＃0。

以下是接收它并将其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;
}

?>

这是Delphi（XE3）代码，它接收POST到服务器的回复：

      bRet:= HttpSendRequest(hRequest,
                             nil,
                             0,
                             PChar(sData),
                             length(sData));
      // choosing Unicode here as the format
      ss:=TStringStream.Create('', TEncoding.Unicode);
      try
        repeat
          if not InternetReadFile(hRequest, @caBuffer, SizeOf(caBuffer), iBytesRead) then
            RaiseLastOSError;

          ss.WriteBuffer(caBuffer, iBytesRead);
        until iBytesRead = 0;

        Result:=ss.DataString;
      finally
        ss.Free;
      end;

从服务器接收回来后，看起来编码是不明确的。我不会惊讶地看到unicode编码从服务器返回，但我不知道如何处理这个文本......

caBuffer包含：

如果我像Unicode一样处理它，我会得到它。

Answer 1

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。这也包括标题。

我不是德尔福专家，但我猜你不是按照你的想法发送JSON。

据我所知，这不应该发生，但无论如何我都会提到它：如果使用压缩，你获得的数据可能会被存档，但正如我所提到的，情况应该不是这样。

除非你得到一个好的标题+内容数据，否则意味着发送了错误的数据。

从Delphi InternetReadFile读取字符串
