Question

关于PHP Array到JSON序列化我确实有一个奇怪的问题：

我有一个多层的数组，并且有一定的大小，它运行得很好。但在某些时候，返回的JSON对象中缺少右大括号。这是返回的标题。

使用SLIM 3 Framework为简单的REST API构建API。

API上的设置：

<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
...

public function listFailedOrders(Request $request, Response $response, array $args) {
  $arr = [];

  //algorithm to fill array
  //verified that the array has data that is not malformed in any way!

  $responseData = [];
  $responseData['count'] = count($arr);
  $responseData['data'] = $arr;

  $response = $response->withJson($responseData, 200);
  return $response;

}

退回数据：

＆＃13;

{
	"count": "41",
	"data": [
		{
           .... JSON DATA ....
		},
		{
           .... More JSON Data ....
		}
	]
//Missing End curly Bracket

＆＃13;

我使用Insomnia Rest客户端来检查这一点，直到这一点，我唯一的解决方案是在接收端添加一个结束的花括号。

TLDR：我将一个大的（不限制到达对象）序列化为JSON，但是尾随的花括号被修剪。问题出在哪里？

问题是预设的“内容长度标头”切断了最后一个花括号。这是一个严重的错误。
