1. The performance of the web page is that when the request parameter is input:\, the response is 200, which in turn causes the response to 500 when the template is rendered. as shown in Figure 1

$在网页端的表现为，在请求参数中输入：\ 时，响应 200，进而导致在渲染模板时响应 500$

Figure 1

2. View the corresponding logs in the Alibaba Cloud Log Service SLS, and report an error when parsing the JSON format: Invalid JSON Syntax Error . as shown in Figure 2

在阿里云日志服务 SLS 中查看相应日志，在解析 JSON 格式时，报错：Invalid json Syntax error

3. Preliminary suspicion should be related to:\, when the input is deleted in the request parameter: \, the template response is 200. as shown in Figure 3

$初步怀疑应该与：\ 有关系，当在请求参数中删除输入：\ 后，渲染模板响应 200$

Figure 3

4. Decide to print the JSON string to be parsed in the test environment. It is found that although the input is \, the request parameter has changed to:\\, and it is already:\ when parsing, which leads to the resolution error. as shown in Figure 4

$决定在测试环境中打印待解析的 JSON 字符串。发现虽然输入的是 \，但是请求参数上已经变化为：\\，解析的时候又已经是：\，进而导致解析错误。$

5. It should still be reserved before the parsing JSON is called. But the current business logic is that after receiving the JSON, it is first stored in the cache (it has changed to \ at this time), and then the JSON is fetched from the cache and put into the template file, and then the JSON parsing is performed. View the error-reported template file. as shown in Figure 5

$应该在调用解析 JSON 之前，仍然保留 \\ 才是。但是现阶段的业务逻辑是，在接收到 JSON 之后，先存储至缓存中（此时已经变化为 \），然后从缓存中取出 JSON 放至模板文件中，再执行 JSON 的解析。查看报错的模板文件$

Figure 5


      
        "": {
          "type": "main-collections",
          "settings": {
            "heading": ""
          },
          "blocks": {
            addLoop($__currentLoopData); foreach($__currentLoopData as $key => $item): $__env->incrementLoopIndices(); $loop = $__env->getLastLoop(); ?>
              "collection-": {
                "type": "collection",
                "settings": {
                  "id": 

                }
              }last): ?>,
            popLoop(); $loop = $__env->getLastLoop(); ?>
          }
        },

6. Edit the original template file, and automatically escape based on the string function addslashes(). Rendering templates no longer report errors. in line with expectations. as shown in Figure 6

编辑原始的模板文件，基于字符串函数 addslashes() 自动转义。渲染模板不再报错。符合预期

Figure 6


      @if($section['type'] === 'collection')
        "{{ $id }}": {
          "type": "main-collections",
          "settings": {
            "heading": "{{ addslashes($section['title']) }}"
          },
          "blocks": {
            @foreach ($section['ids'] as $key => $item)
              "collection-{{ $key }}": {
                "type": "collection",
                "settings": {
                  "id": {{ $item }}
                }
              }@if (!$loop->last),@endif
            @endforeach
          }
        },
      @endif

7. However, after entering, “” character, the response is 500. Parsing failed. as shown in Figure 7

Figure 7

8. Check the PHP template code after the rendering, e(addslashes($Section[‘title’])


      
        "": {
          "type": "main-collections",
          "settings": {
            "heading": ""
          },
          "blocks": {
            addLoop($__currentLoopData); foreach($__currentLoopData as $key => $item): $__env->incrementLoopIndices(); $loop = $__env->getLastLoop(); ?>
              "collection-": {
                "type": "collection",
                "settings": {
                  "id": 

                }
              }last): ?>,
            popLoop(); $loop = $__env->getLastLoop(); ?>
          }
        },

9. What I thought \Converted to:\"

10. Decide to modify the Blade template source code, use {!! !!} to prevent the occurrence of step 9


{!! addslashes($section['title']) !!}

11. In the inputWhen characters, although the format has changed to: \, the response 500. Parsing failed. as shown in Figure 8

$在输入 ' 字符时，虽然格式已经变化为：\'，响应 500。解析失败$

12. The final decision is to escape only \, based on addcslashes — use the characters in the backslash to escape the string in C style


{!! addcslashes($section['title'], '\\') !!}

13. Request parameters:,The parsing has been successful. as shown in Figure 9

Figure 9

14. When entering the “character, the request parameter: \”, ” has failed to parse. As shown in Figure 10

$在输入 " 字符时，请求参数：\"，" 已经解析失败$

Figure 10

15. At this point, the escape of JSON should be consistent with the front-end, escape \ and “


{!! addcslashes($section['title'], '\\"') !!}

16. When entering the “character, the request parameter: \”, \” has been parsed successfully. As shown in Figure 11

$在输入 " 字符时，请求参数：\"，\" 已经解析成功$

Figure 11

17. Test the input of js code, the js script is not executed, because the json format is only for parsing, when rendering the template, it will still pass the php htmlspecialchars function to prevent xss attacked. as shown in Figure 12

测试一下 js 代码的输入，未执行 js 脚本，因为 JSON 格式仅用于解析，在渲染模板时，仍然会经过 PHP 的 htmlspecialchars 函数传递来防范 XSS 攻击的

Figure 12



alert("Hello! I am an alert box!");

18. The following characters are reserved characters and cannot be used in JSON. They must be properly escaped to use in strings. Any character except ” or \ or control characters. Reference URL:https://www.json.org/json-zh.html. If the data entered by the front-end is received in rich text, the following characters need to be escaped. as shown in Figure 13

$以下字符是保留字符，不能在 JSON 中使用，必须正确转义才能在字符串中使用。除 " 或 \ 或控制字符外的任何字符。参考网址：https://www.json.org/json-zh.html 。如果在富文本中接收前端输入的数据，则以下字符皆需要转义$

Figure 13


Backspace to be replaced with \b

Form feed to be replaced with \f

Newline to be replaced with \n

Carriage return to be replaced with \r

Tab to be replaced with \t

quotation mark \"

Backslash to be replaced with \\

19. When entering a newline character, the request parameter:\n,\n has failed to parse. Figure 14

$在输入换行字符时，请求参数：\n，\n 已经解析失败$

Figure 14


{
                  "heading": "\\\"'


IMAGE WITH TEXT1"
                }


{!! addcslashes($section['horizontal']['title'], '\n\\"') !!}

20. Adjust the charlist parameter of addcslashes, use “” to include. Parsing is successful. as shown in Figure 15

调整 addcslashes 的 charlist 参数，使用 "" 包含。解析成功

Figure 15


{!! addcslashes($section['horizontal']['title'], '\n\\"') !!}

20. You don’t usually have to think about escape characters yourself when you generate JSON programmatically (of course, you will consider manually editing a configuration file such as a JSON based). Instead, use any native mappings, arrays, strings, numbers, booleans, and null types that your language has to form the data structure you want to encode, and then use a JSON encoding function to encode it as JSON. Such functions may be built into any language you use, such as JavaScript’s json.stringify, php’s json_encode. It is now determined that the JSON-based configuration file is manually edited in the template file.

21, but \b will replace b in the value

$json = '{"title": "' . addcslashes($title, "\b\f\n\r\t\\\"") . '"}';

$obj = json_decode($json);

// var_dump($obj);

echo $obj->{'title'};

?>

22. But \u will cause the resolution to fail

HTML;

echo "$title\n\n\n";

$json = '{"title": "' . addcslashes($title, "\b\f\n\r\t\u\\\"") . '"}';

$obj = json_decode($json);

// var_dump($obj);

echo $obj->{'title'};

?>

Notice:  Trying to get property 'title' of non-object in E:\wwwroot\addcslashes.php on line 19

23. The final demonstration example, the output is as expected. as shown in Figure 16
