注意所有有才华的编码人员，首先，让我从保存开始，我对 JSON 的经验为零，而服务器端编码经验不多。这是我正在尝试做的事情：

我想用 Java 或 PHP 构建一个非常简单的后端服务器，它响应 get 命令并根据关键字返回 2 个不同的 JSON 结果（即，如果关键字以 A 开头或为空，则返回一个结果。如果它以 B 开头，返回一个不同的）。再一次，我不知道如何解决这个问题，如果有人能为我解决这个问题，我将不胜感激。这不是家庭作业，我只是想学习和掌握一些技能。如果有人真的喜欢编码并且有空闲时间，请帮助我了解这是如何完成的。任何帮助是极大的赞赏。真的。提前非常感谢大家。

这是我尝试过的。我最终想在搜索关键字时发送如下所示的 JSON onbect。

 <?php


    $data = $_GET['keyword'];


      $nullOrA = substr($data, 0)

     if($nullOrA != "A" || "B" || "C"){
    echo "Cannot find anything related to searched Keyword"; 
    }

  if($nullOrA == "A"){
    echo json_encode($candStr); 
}

if($nullOrA == "B"){
    echo json_encode($jobStr); 
}

else if($nullOrA == "C"){
    echo json_encode($companyStr); 
}

//JSON object
 $Response Object:

$candStr = {"candidates": [
        {"lastName":"Doe" , "firstName":"John" , "mailingState":"IN" , "availDate:":"08/15/2013" , "matchPct":"92%", "division":"temps" , "branch":"Branch AA"},

我建议你可以从一个非常简单的 php 教程开始

但是，这可能会让您入门：

<?php
if ($_GET["keyword"]=="B") {
    echo "a different one!";
} else {
    echo "one result.";
}

您现在应该可以访问http://yourserver/path/yourphp.php?keyword=Agetone result.和http://yourserver/path/yourphp.php?keyword=Bgeta different one!
