如何为JavaScript和JSON正确编码UTF-8？ [英] How to properly encode UTF-8 for JavaScript and JSON?
问题描述
我在创建输入验证哈希时遇到问题。 JavaScript将数据提交给API，API使用json_encode验证发送的数据。基本上它的工作方式如下：
I have a problem creating an input validation hash. JavaScript submits data to API and API validates the sent data with json_encode. Basically it works like this:
$input=array('name'='John Doe','city'=>'New York');
$validationHash=sha1(json_encode($input).$key); // Key is known to both servers
如果PHP连接到另一台服务器，那么一切正常。它也可以通过JavaScript工作（我也有自定义sha1（）函数）：
If PHP connects to another server, then everything works. It also works through JavaScript (I have a custom sha1() function there as well):
var validationHash = sha1（JSON.stringify（{'name'：'John Doe'，'city'=>'New York'}）+ key）;
var validationHash=sha1(JSON.stringify({'name':'John Doe','city'=>'New York'})+key);
当字符串包含UTF-8字符时，我的问题出现了。例如，如果其中一个值为：
My problem comes when the string contains UTF-8 characters. For example, if one of the values is:
Ränisipelgasöösel
接收命令的PHP服务器在JSON编码后将其转换为此值：
Then PHP server that receives the command converts it to this after JSON encoding:
R\u00e4nisipelgas\u00f6\u00f6sel
我需要在JavaScript中执行此操作好吧，但我还没弄清楚如何。我需要确保向服务器发送适当的验证哈希或命令失败。我从谷歌发现可以使用unescape（encodeURIComponent（string））和decodeURIComponent（），但是它们都没有给我与PHP有相同的字符串并验证。
I need to do this in JavaScript as well, but I haven't been able to work out how. I need to make sure that I send proper validation hash to the server or the command fails. I found from Google that unescape(encodeURIComponent(string)) and decodeURIComponent() could be used, but neither gives me the same string that PHP has and validates with.
UTF -8用于客户端和服务器。
UTF-8 is used on both client and server.
任何想法？
推荐答案
似乎不可能。我发现唯一可行的解决方案是在浏览器端使用encodeURIComponent（）编码所有数据，在PHP端使用rawurlencode（）编码，然后从数组中的这些值计算JSON。
It does not seem to be possible. The only working solution I have found is to encode all data with encodeURIComponent() on browser side and with rawurlencode() on PHP side and then calculate the JSON from these values in arrays.
