【中文标题】无法从 Postal Pincode API 获取数据【英文标题】：Unable to get data from Postal Pincode API 【发布时间】：2021-07-17 11:03:58 【问题描述】：我在functions.php 中创建了一个wordpress 函数来从API URI 获取pincode 详细信息。我想以我的形式从 API 获取城市和州。这是我的 wordpress 功能。
add_action( 'wp_enqueue_scripts', function ()
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
);
function get_pincode ()
$pincode=$_POST['pincode'];
$data=file_get_contents('http://postalpincode.in/api/pincode/'.$pincode);
$data=json_decode($data);
if(isset($data->PostOffice['0']))
$arr['city']=$data->PostOffice['0']->Taluk;
$arr['state']=$data->PostOffice['0']->State;
echo json_encode($arr);
else
echo 'no';
add_action( 'wp_ajax_get_pincode', 'get_pincode' );
这是我试图获取值的表单

这是我的 jQuery json 解析器脚本
<script>
function get_details()

if(pincode=='')
jQuery('#form-field-city').val('');
jQuery('#form-field-state').val('');
else
jQuery.ajax(
action: 'get_pincode',
type: 'POST',
dataType: 'json',
data:'pincode='+pincode,
success:function(data)
console.log('Submission was successful.');
if(data=='no')
alert('Wrong Pincode');
jQuery('#form-field-city').val('');
jQuery('#form-field-state').val('');
else
var getData=JSON.parse(data);
jQuery('#form-field-city').val(getData.city);
jQuery('#form-field-state').val(getData.state);
,
error: function (data)
console.log('An error occurred.');
console.log(data.pincode);
);
jQuery("#form-field-pincode").keyup(function()
get_details();
);
</script>
请帮我找出错误。
谢谢
【问题讨论】：
你遇到了什么问题？ @ZamAbdulVahid 我不确定我是否正确调用了 API。在我的控制台中，我看到“发生错误”。 【参考方案1】：相信您使用的数据提交 URL 为action: 'get_pincode'。它应该是url: 'get_pincode'。确保get_pincode 是您在 php 文件中定义的方法的完整且正确的 url。
jQuery.ajax(
url: 'get_pincode',
type: 'POST',
dataType: 'json',
data: 'pincode='+pincode,
success:function(data)
console.log('Submission was successful.');
if(data ==='no')
alert('Wrong Pincode');
jQuery('#form-field-city').val('');
jQuery('#form-field-state').val('');
else
var getData=JSON.parse(data);
jQuery('#form-field-city').val(getData.city);
jQuery('#form-field-state').val(getData.state);
,
error: function (data)
console.log('An error occurred.');
console.log(data.pincode);
);

POSThttps://forthetruth.abny.in/register/get_pincode [HTTP/2 404 Not Found 2992ms] 如果替换为 url，我会看到 404 错误这是我想要获取结果的页面。
@HarshitSingh 你的 wordpress 版本是什么？你设置好 wp_enqueue_script & wp_localize_script 了吗？
Wordpress 版本 5.7.1。我已经完成 wp_enqueue_script 不确定 wp_localize_script
@HarshitSingh 你能把wp_enqueue和相关的php代码更新到问题中吗
更新问题，请看。以上是关于无法从 Postal Pincode API 获取数据的主要内容，如果未能解决你的问题，请参考以下文章
