在Ajax POST和JSON中发送特殊字符 [英] Sending special characters in Ajax POST and JSON

问题描述

@已解决

正如James M. Lay解释的那样，我应该将内容类型从application/x-www-form-urlencoded更改为application/json

As explained by James M. Lay, I should change my content-type from application/x-www-form-urlencoded to application/json

暗示一个错误，因为似乎只有UrlEnconded类型在服务器端(至少在PHP中)生成POST数组.因此，我必须更改服务器脚本中请求的接收/处理方式

it implied in an error because it seems that only UrlEnconded types generates POST arrays in server side (at least in PHP). So I had to change the way I receive/deal with the request in my server script

$json = file_get_contents('php://input'); //yes. php://input

if($json) $params = json_decode($json,true);
else $params = $_POST;

我还必须对Javascript代码进行一些更改，以检查内容类型并生成不同的字符串.如果是JSON，我只需使用JSON.stringify

I also had to make a few changes in the Javascript code to check the content-type and generate different strings. If it's JSON I just use JSON.stringify

//string to use in the 'send' method
this.getParametersString = function(){
        if(this.contentType == 'application/json'){
            return JSON.stringify(this.parameters);
        }else{}
}

我有一个问题

I got a question

我正在构建一个函数，该函数接收参数以编写参数列表并通过POST发送

I`m building a function that receive parameters to write a list of parameters and send it by POST

问题是我们无法发送特殊字符，例如+

The problem is that we can't send special characters, such is +

所以我尝试使用功能encodeURIComponent将它们编码为URI友好字符串.

So I tried to use the function encodeURIComponent to encode them to a URI friendly string.

还有另一个问题:如果接收到的参数是一个对象，我将遍历属性，检查它是另一个对象还是字符串，如果是对象，则再次循环，否则对其进行编码.

There comes another problem: if the parameter received is an object, I am loop through the attributes, checking if it is another object or a string, if it is an object, loop again, otherwise encode it.

但是它返回一个编码字符串的对象.我必须使该对象成为发送它的字符串，为此，我使用JSON.stringify.它解码编码的字符串.因此%2B再次变为+，并且不会通过POST发送到服务器.

But it is returning an object of encoded strings. I have to make the object become a string to send it, and for that purpose I use JSON.stringify. It decodes the encoded string. So %2B becomes + again and It is not sent to the server via POST.

我先使用stringify和encodeURIComponent，它将生成不应被编码且字符串不是写得好的JSON的符号，例如和{}

on the other hand If I use stringify first and the encodeURIComponent it generates signs like " and { } that shouldn't be encoded and the string is not a well written JSON

那你怎么样?这是不使用jQuery的方法吗?我必须构建自己的stringify函数吗?！

How do you that? Is that a way without using jQuery? Do I have to build my own stringify function?!

推荐答案

im使用以下内容，但我没有任何问题

im using the following and i have no issues

encodeURIComponent(JSON.stringify(object_to_be_serialised))
