php - 如何在 AngularJS 和 PHP 中获取最大数量的 JSON 记录作为响应

Question

我试图获取 >30,000 条记录作为 JSON 数据，我无法获得正确的响应。但我尝试了 PHP 服务 直接打印 JSON，它打印的是实际记录，没有任何错误。但是在 AngularJS 中，我无法获取实际的记录数。

我的示例 JSON 数据

{
   "records":[
      {
         "ldat":"2014-08-13",
         "eid":"HSL018",
         "dr":"55420",
         "cr":"0",
         "bal":"55420"
      },
      {
         "ldat":"2014-10-11",
         "eid":"HBL056",
         "dr":"0",
         "cr":"35000",
         "bal":"20420"
      },
      {
         "ldat":"2014-10-26",
         "eid":"HBL001",
         "dr":"0",
         "cr":"420",
         "bal":"20000"
      },


      ----- 30,000 Records -----

      ,
      {
         "ldat":"2015-11-01",
         "eid":"HDL001",
         "dr":"0",
         "cr":"20000",
         "bal":"0"
      }
   ]
}

在调试时，我只从响应中获得了部分输出。

{
   "records":[
      {
         "ldat":"2014-08-13",
         "eid":"HSL018",
         "dr":"55420",
         "cr":"0",
         "bal":"55420"
      },
      {
         "ldat":"2014-10-11",
         "eid":"HBL056",
         "dr":"0",
         "cr":"35000",
         "bal":"20420"
      },
      {
         "ldat":"2014-10-26",
         "eid":"HBL001",
         "dr":"0",
         "cr":"420",
         "bal":"20000"
      },


      ----- 4,000 Records -----

      ,
      {
         "ldat":"2015-11-01",
         "eid":"HDL0

让我知道 Response 是否有任何限制？如何获取整个记录作为响应？请帮助我...

得到的Response Header Details

HTTP/1.1 200 OK
Date: Thu, 11 Feb 2016 01:31:45 GMT
Server: Apache
Access-Control-Allow-Origin: *
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
Vary: Accept-Encoding
Content-Encoding: gzip
Keep-Alive: timeout=10, max=500
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/json; charset=UTF-8

我的 PHP 服务脚本

<?php
    ob_start(); // start normal buffer
    ob_start("ob_gzhandler"); // start gzip buffer
    echo $content;
    ob_end_flush(); // output gzipped content

    $gzippedContent = ob_get_contents(); // store gzipped content to get size
    header('Content-Length: '.strlen($gzippedContent));
    ob_end_flush(); // flush gzipped content
?>

Use the following PHP Script to test the task, it will produce the 35,000 records.

PHP 脚本:Statement.php

<?php
    header("Access-Control-Allow-Origin: *");
    header("Content-Type: application/json; charset=UTF-8");

    $content = "";
    for($i=1; $i<=35000; $i++) {
        if ($content != "") {
            $content .= ",";
        }
        $content .= '{"slr":' . $i . ',';
        $content .= '"uid":' . rand(100,10000) . ',';
        $content .= '"name":"Balamanigandan",';
        $content .= '"cell":"9999999999",';
        $content .= '"balance":10000,';
        $content .= '"ltrans":"2015-01-01",';
        $content .= '"msg":" Opening Balance"}';
    }
    $content = '{"records":[' . $content . ']}';

    ob_start(); // start normal buffer
    ob_start("ob_gzhandler"); // start gzip buffer
    echo $content;
    ob_end_flush(); // output gzipped content

    $gzippedContent = ob_get_contents(); // store gzipped content to get size
    header('Content-Length: '.strlen($gzippedContent));
    ob_end_flush(); // flush gzipped content
?>

用于获取记录的 AngularJS 示例脚本

var stmt= angular.module('Statement', []);

stmt.controller('StmtCtrl', function($scope, $http, $cacheFactory) {

    var request = $http({
        method: "post",
        url: "Statement.php",
        headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
    });

    request.success(function (response) 
    {   
        $scope.data = response;
    });

});

Note: I don't get any error, but I'm getting the partial output as a Response.

您将在内容本身之后发送 Content-Length header (并且该 header 不会出现在您列出的 header 详细信息中)。标题应该首先发送。也许这就是原因？
