I am generating a concatenated string in Javascript:
我在Javascript中生成连接字符串:
var result = '';
for (i = 0; i < j.result.length; i++) {
// bunch of string formatting code here
result += stringAsWeGo;
}
This "result" string is a string object formatted to look like JSON...I want to save this string as a .json file on my server. So I am using AJAX and PHP like this:
这个“结果”字符串是一个格式化为JSON的字符串对象...我想将此字符串保存为我的服务器上的.json文件。所以我使用这样的AJAX和PHP:
var obj = JSON.parse(result);
$.ajax({
url: 'json.php',
data: obj,
dataType: "json",
type: "POST"
});
Where my json.php file looks like this:
我的json.php文件看起来像这样:
<?php
$json = $_POST['json'];
$file = fopen('jsonfile.json', 'w+');
fwrite($file, $json);
fclose($file);
?>
But nothing is writing to the server. The existing blank jsonfile.json file is empty with no json in it.
但没有任何东西写入服务器。现有的空白jsonfile.json文件为空,其中没有json。

Looks like you don't have a param named json
so try
看起来你没有一个名为json的param,所以试试吧
//var obj = JSON.parse(result);
$.ajax({
url: 'json.php',
data: {
json: result
},
dataType: "json",
type: "POST"
});
Note: Don't create a json object using string concatenation. You can create an object then use JSON.stringify()
to sent the value to server as a param value.
注意:不要使用字符串连接创建json对象。您可以创建一个对象,然后使用JSON.stringify()将值作为参数值发送到服务器。
var obj = {};
//do some processing here which adds some properties to obj like
obj.name = 'x';
obj.id = 4
$.ajax({
url: 'json.php',
data: {
json: JSON.stringify(obj)
},
dataType: "json",
type: "POST"
});
