Json_encode，json_decode和UTF8 [英] Json_encode, json_decode and UTF8

问题描述

全部

我使用PHP向Web服务器发出JSON请求，它在变量中返回了JSON响应. JSON响应将包含许多键和值.我从服务器获得的JSON响应中包含特殊字符.因此，我使用以下语句将其转换为UTF8，对JSON进行解码，并将其用作显示到UI的数组.

I make a JSON request to a web server using PHP and it returns me a JSON response in a variable. The JSON response will have lots of keys and values. The JSON response I get from the server has special characters in it. So, I use the following statement to convert it to UTF8,decode the JSON and use it as an array to display to the UI.

$response = json_decode(utf8_encode($jsonresponse));

现在，我必须在JSON请求中将相同的值传递给服务器以执行某些操作.但是，当我通过

Now, I have to pass the same value to the server in a JSON request to do some stuff. However, when I pass

$jsonrequest = json_encode(utf8_encode($request));

到服务器，它失败.

以下代码成功读取特殊字符并将其显示在UI中.但是如果我必须将utf8_encode值传递到服务器，则会失败.

The following code succeeds in reading special characters and displaying it to the UI. But fails if I have to pass the utf8_encode value to the server.

当前的整个往返代码如下:

The current whole roundtrip code is as under:

$requestdata  = json_encode($request);
$jsonresponse = //Do something to get from server;
$response = json_decode(utf8_encode($jsonresponse));

如何修改它，以便我传递服务器接收到的来自json响应的确切值?

How can I modify it such that I pass the exact value as to what I receieved from the json response from the server?

JSON数据已经以UTF-8编码.您不应该再次将其转换为UTF-8.您将破坏数据.

JSON data already comes encoded in UTF-8. You shouldn't convert it to UTF-8 again; you'll corrupt the data.

代替此:

$response = json_decode(utf8_encode($jsonresponse));

您应该有这个:

$response = json_decode($jsonresponse); //already UTF-8!
