无效的JSON分析器错误

时间:2013-04-26 03:54:45

标签: javascript asp.net-mvc json jqgrid

我有一个对象,其属性包含quote('),斜杠(/)或Environmental.NewLine

我将此对象构造为JSON字符串并尝试将其分配给jQGrid。

但它显示Invalid JSON Parser error

如何成功解析此问题。

 myObj=new {Text=@"Samp'le value"}

在ASP.Net MVC中,return JSON(myObj)用于构造JSON。

是否有任何人有任何想法,我们需要配置以在解析JSON时处理此' / Environmental.NewLine(\n)

我们需要使用任何其他库来处理Newtosoft JSON

来自服务器的JSON

     {"total":1 ,"page":1,"records":3,"rows":[{"i":0,"cell":"","1","1","DesSinglApostropAndURLhasEnterKeyChar",
"Samp'le value","http://google.com/Dashboard.aspx?ParcelNbr= {SITE_APN}","False","",""]},"i":1,"cell":"","2","2","DesWithSlashAndURLwithSlash",
 "Sample\value2","http://Googole.com/Dashboard.aspx?ParcelNbr={SITE_APN}&ABC=\XYZ","False","",""]},{"i":2,"cell":["","3","3","DesWithAmpersand","Sample & value3"","http://Googole.com","False","",""]}]}

对应于规范(请参阅herehere),只有"\个字符必须转义。其他一些字符可以转义。因此,未转义的'字符不是错误。我认为还有另一个原因导致错误“无效的JSON解析器错误”。

您应该包含更多完整的JavaScript代码,其中显示了如何使用jqGrid,ASP.NET MVC控制器操作的代码或更多返回服务器的完整JSON响应。通常,您可以在没有Json.NET(Newtosoft)或使用它或任何其他库的情况下生成正确的JSON响应。

您应该包含autoencode: true选项以在jqGrid中正确显示任何文本数据。您应该使用datatype: "json"jsonReader选项(请参阅the documentation)。因此仅仅生成格式良好的JSON或XML数据以在jqGrid中正确显示数据是不够的。可能需要包含jqGrid选项,它提供有关数据的确切格式的信息。

更新:您发布的JSON数据确实已损坏。 jsonlint.org是一个可以验证JSON数据的好地方。您可能尝试手动生成JSON数据,因为数据绝对错误:

{
    "total": 1,
    "page": 1,
    "records": 3,
    "rows": [
        {
            "i": 0,
            "cell": "", <---- it must be "cell": [""
            "1",
            "1",
            "DesSinglApostropAndURLhasEnterKeyChar",
            "Samp'le value",
            "http://google.com/Dashboard.aspx?ParcelNbr= {SITE_APN}",
            "False",
            "",
            ""
        ]
    },
    "i": 1, <--- it must be {"i": 1
    "cell": "",
    "2",
    "2",
    "DesWithSlashAndURLwithSlash",
    "Sample\value2",  <--- it must be "Sample\\value2" or "Sample value2"
    "http://Googole.com/Dashboard.aspx?ParcelNbr={SITE_APN}&ABC=\XYZ", <--- \XYZ is WRONG
    "False",
    "",
    ""
]
},
{
"i": 2,
"cell": [
    "",
    "3",
    "3",
    "DesWithAmpersand",
    "Sample & value3"","http: //Googole.com","False","",""]}]} <-- "Sample & value3"" is WRONG

数据包含5个语法错误:

  • 使用"cell": ""代替"cell": [""
  • 使用}, "i": 1,代替}, {"i": 1,
  • 使用"Sample\value2"代替"Sample value2""Sample\\value2"
  • 使用"http://Googole.com/Dashboard.aspx?ParcelNbr={SITE_APN}&ABC=\XYZ"代替"http://Googole.com/Dashboard.aspx?ParcelNbr={SITE_APN}&ABC=XYZ""http://Googole.com/Dashboard.aspx?ParcelNbr={SITE_APN}&ABC=\\XYZ"
  • 使用"Sample & value3""代替"Sample & value3""Sample & value3\""

此外,您使用i属性而不是id"i": 1必须固定为"id": 1)。这不是JSON中的错误,但是您应该为jqGrid生成数据,因此您应该保持jqGrid所期望的格式。见the documentation。固定的JSON响应应该类似于

{
    "total": 1,
    "page": 1,
    "records": 3,
    "rows": [
        {
            "id": 0,
            "cell": [
                "",
                "1",
                "1",
                "DesSinglApostropAndURLhasEnterKeyChar",
                "Samp'le value",
                "http://google.com/Dashboard.aspx?ParcelNbr= {SITE_APN}",
                "False",
                "",
                ""
            ]
        },
        {
            "id": 1,
            "cell": [
                "",
                "2",
                "2",
                "DesWithSlashAndURLwithSlash",
                "Sample value2",
                "http://Googole.com/Dashboard.aspx?ParcelNbr={SITE_APN}&ABC=XYZ",
                "False",
                "",
                ""
            ]
        },
        {
            "id": 2,
            "cell": [
                "",
                "3",
                "3",
                "DesWithAmpersand",
                "Sample & value3",
                "http: //Googole.com",
                "False",
                "",
                ""
            ]
        }
    ]
}

我建议您分析使用ASP.NET MVC和jqGrid的示例代码(例如,参见here)并修复服务器代码。
