未捕获的语法错误:意外的标记-JSON字符编码 - Uncaught SyntaxError: Unexpected token - JSON character encoding

Uncaught SyntaxError: Unexpected token - JSON character encoding

在我的控制器中，我用ajax处理POST请求，并将GET请求中的数据直接添加到js代码中

mycontroller.php

$sServiceNumber = isset($_POST['ServiceNumber']) ? $_POST['ServiceNumber'] :  $_GET['ServiceNumber'];
//Here I do a db call for sServiceNumber and fetch some data as array $aAllrows
$aResponse['ServiceNumber'] = $sServiceNumber;
$aResponse['Data'] = $aAllrows;
$sJson = json_encode(self::convertToStrictUtf8($aResponse));
if (isset($_POST['ServiceNumber'])) {
    echo $sJson;
    exit;
} else {
    $sJs = '
    $(document).ready(function() {
        var sData = ''' . $sJson . ''';
        handleResponseData(sData);
    });';
    MyHtmlHead::addExtraJsCode($sJs);
    //continue with rendering html page here..
}

当我用ajax调用它时，一切都很好，但当我尝试直接运行handleResponseData()时，我会在特殊字符上得到Uncaught SyntaxError: Unexpected token。

我的JavaScript

function handleResponseData ( rawData ) {
    response = jQuery.parseJSON(rawData);  //<--this is where the error occurs (on GET requests)
    //Make use of response data
}
$("form[name='searchform']").submit(function( event ) {
    event.preventDefault(); 
    // Send post and fetch some data!
    $.post(baseUrl, { ServiceNumber: $("input[name='ServiceNumber']").val(), time: "2pm" }).done(handleResponseData);
});

最后是我的转换方法

protected static function convertToStrictUtf8 ($p_aValues) {
    function detectEncoding(&$mValue) {
        if (!mb_detect_encoding($mValue, 'UTF-8', true)) {
            $mValue = utf8_encode($mValue);
        }
    }
    array_walk_recursive($p_aValues, 'detectEncoding');
    return $p_aValues;
}

为什么json字符串在使用jquery $.post提取时解析良好，而在手动嵌入到代码中时解析不好？我该如何解决此问题？

编辑：从console.log(rawData) 剥离rawData版本

获取

{"ServiceNumber":"485218-1138932068","Data":[{"RowId":"AEEA-IU3A61","ServiceRequestId":"AEEA-IU39LX","Name":"SV LIDEHÄLL)","FileSize":"8812","ServiceNumber":"485218-1138932068","Subject":"O(BERGMAN/LIDEHÄLL)
","Area":"svrT","Dir":"1702"}]}

后

{"ServiceNumber":"485218-1138932068","Data":[{"RowId":"AEEA-IU3A61","ServiceRequestId":"AEEA-IU39LX","Name":"SV LIDEH'u00c4LL)","FileSize":"8812","ServiceNumber":"485218-1138932068","Subject":"O(BERGMAN'/LIDEH'u00c4LL)'r'n","Area":"svrT","Dir":"1702"}]}

问题是由Line breaks引起的。

正如jQuery.parseJSON（）文档所述：不允许使用制表符或换行符等"控制字符"。

当用$.post调用时，新行字符被转换为字符串"'r'n"，这就是为什么这种情况有效的原因。

添加这样的东西来删除新行最终解决了这个问题

function stripNewLines(&$mValue) {
    if(is_string($mValue)) {
        $mValue = trim(preg_replace('/'s+/', ' ', $mValue));
    }
}
array_walk_recursive($aResponse, 'stripNewLines');

在PHP控制器中，在echo JSON respose之前，键入以下行

header("Content-Type: application/json");

而且在jQueryAjax调用中，您需要提到数据类型为JSON

$.ajax({
 ...,
 ...,
 dataType: 'JSON', // it is necessary to get JSON response 
 ...
});
