问题描述
所以我试图将JSON作为字符串发送。
然后我有一个PHP后端,它检索这个JSON字符串并使用 json_decode
解析它。
So I'm trying to send a JSON as a string.Then I have a PHP back-end that retrieves this JSON string and parses it using json_decode
.
不幸的是,我无法将此JSON作为字符串发送。
Unfortunately, I can't get to send this JSON as a string.
这是我使用的jQuery Ajax脚本:
Here's the jQuery Ajax script I used:
var jsonString = JSON.stringify(checkables);
console.log(jsonString);
$.ajax({
url: $url,
type: 'POST',
data: {ajaxidate: JSON.stringify(jsonString)},
contentType: "application/json; charset=UTF-8",
success: function (data)
{
// just successful callback
},
error: function ()
{
// just error callback
}
});
变量 checkables
包含原始形式作为JSON数据:
Variable checkables
contains raw form as JSON data:
应用 JSON.stringify()
后,这是现在的样子:
[{name:name,type:multialphanumslug,value:AD},{name:服务器 类型: 主机, 值: 10.1.1.1},{ 名称: 端口, 类型: 号码, 值: 8080},{ name:authid,type:username,value:barryallen}]
After applying JSON.stringify()
, this is now how it looks:[{"name":"name","type":"multialphanumslug","value":"AD"},{"name":"server","type":"host","value":"10.1.1.1"},{"name":"port","type":"number","value":"8080"},{"name":"authid","type":"username","value":"barryallen"}]
在后面 - 结束,我有这个PHP脚本:
At the back-end, I have this PHP script:
<?php
var_dump($_POST);
die();
?>
现在我认为后端的$ _POST现在应该包含这个:
Now I suppose $_POST at back-end should now contain this:
数组(
'ajaxidate'=>[{\name \:\name \,\type \:\multialphanumslug \ \ value\:\ AD\},{\ name\:\ server\,\ type\:\ 宿主\,\ value\:\ 10.1.1.1\},{\ name\:\ port\,\ type\:\ number\,\ value\:\ 8080\},{\ name\:\ authid\,\ type\:\ username \,\value \:\barryallen \}]
);
array( 'ajaxidate' => "[{\"name\":\"name\",\"type\":\"multialphanumslug\",\"value\":\"AD\"},{\"name\":\"server\",\"type\":\"host\",\"value\":\"10.1.1.1\"},{\"name\":\"port\",\"type\":\"number\",\"value\":\"8080\"},{\"name\":\"authid\",\"type\":\"username\",\"value\":\"barryallen\"}]");
但它没有什么都收到以下是捕获的请求:
But it didn't receive anything. Here's the captured request:
来自后端?
我试过POSTMan我收到了预期的正确输出:
I tried with POSTMan and I received an expected correct output:
现在这太荒谬了。
我被困在这两天,试图弄清楚发生了什么或者我错过了什么。任何帮助将不胜感激。
I'm stuck at this for 2 days trying to figure out what's going on or what did I miss. Any help will be greatly appreciated.
推荐答案
您需要解析服务器上的数据:
You need to parse the data on the server:
$myArray = json_decode($_POST['ajaxidate']);
var_dump($myArray);
考虑一下:
<?php
$a = '[{"a": 1}]';
$b = json_decode($a);
var_dump($a);
var_dump($b);
?>
输出:
string(10) "[{"a": 1}]"
array(1) {
[0]=>
object(stdClass)#1 (1) {
["a"]=>
int(1)
}
}
dataType:'json'
,tldr:使用它!
dataType: 'json'
, tldr: Use It!
设置dataType = json时告诉jQuery来自服务器的响应应解释为JSON,因此它将为您解析它并将解析的对象/数组作为成功回调的第一个参数:
When setting dataType = json you tell jQuery that the response from the server should be interpreted as JSON and it will therefore parse it for you and give the parsed object / array as first argument to the success callback:
$.ajax({
// ...
dataType: 'json',
success: function(myJson) {
console.log(myJson); // this will be a JSON object/array...
}
});
