服务器端 - 创建JSON响应

注意所有优秀的编码人员，首先，让我从保存开始我有ZERO使用JSON的经验，没有太多的服务器端编码经验。以下是我正在尝试执行的操作：服务器端 - 创建JSON响应

我想在Java或PHP中构建一个非常简单的Backend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开头或者是空的，返回一个结果，如果它以B开头，返回一个不同的结果）。再一次，我不知道如何去解决这个问题，如果有人能为我解决这个问题，我将不胜感激。这不是作业，我只是想学习和拾取一些技能。如果有人真的喜欢编码并有时间空闲，请帮我理解这是如何完成的。任何帮助是极大的赞赏。真。提前感谢大家。

这是我试过的。我最终希望在搜索关键字时发送如下所示的JSON副本。

<?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"},

JSON只是一种格式，你不需要“JSON体验”。在着手一些你知之甚少的事情之前，你应该改善你的后端技能，教程和书籍是有原因的。 –

我建议你不妨用very simple php tutorial

但是启动，这可能让你开始：

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

您现在应该能够访问http://yourserver/path/yourphp.php?keyword=A得到one result.，并http://yourserver/path/yourphp.php?keyword=B得到a different one!
