Question

服务器端响应是text / html，但我希望它是application / json，我做错了什么？

$.ajax({
        type:'GET',
        url: 'http://pda.bilgiteknolojileri.net',
        dataType: 'json',
        contentType: "application/json",
        crossDomain: true,
        success: function(categories) {
            $.each(categories.data, function(i, data) {
                var cat=data.cat;
                var cat_id=data.cat_id;
                $('#category').append('<option value="'+cat_id+'">'+cat+'</option>');
            });
        }
    });

服务器端标头响应代码以：

开头

<html>
    <head></head>
    <body>

        <pre style="word-wrap: break-word; white-space: pre-wrap;">

                {"status":"ok","count":351,"data":[

和服务器端代码：

<html>
    <head></head>
    <body>
        <cfif isdefined('attributes.cat_id')>
            <cfquery name="GET_PRODUCT_CATS" datasource="#DSN3#">
                    SELECT PRODUCT_CAT,IS_CUSTOMIZABLE,HIERARCHY FROM PRODUCT_CAT WHERE PRODUCT_CATID = #attributes.cat_id#

        </cfif>
        <cfquery name="get_json" datasource="#dsn3#">
            SELECT P.PRODUCT_ID,P.PRODUCT_NAME,PC.PRODUCT_CAT,PC.PRODUCT_CATID,PR.PRICE,PR.MONEY,PC.HIERARCHY

            LEFT OUTER JOIN PRODUCT P ON P.PRODUCT_CATID=PC.PRODUCT_CATID
            LEFT OUTER JOIN PRICE PR ON P.PRODUCT_ID=PR.PRODUCT_ID
            WHERE P.IS_SALES=1 AND P.IS_EXTRANET=1 AND PR.PRICE IS NOT NULL
                <cfif isdefined('attributes.cat_id') and len(attributes.cat_id)>
                    AND (PC.PRODUCT_CATID = <cfqueryparam value="#attributes.cat_id#" cfsqltype="cf_sql_integer"> OR PC.HIERARCHY LIKE <cfqueryparam value="#GET_PRODUCT_CATS.HIERARCHY#.%" cfsqltype="cf_sql_varchar"> )
                </cfif>

            ORDER BY PC.HIERARCHY,P.PRODUCT_NAME

        <cfset row=0>
        <cfoutput query="get_json" group="product_catid">
            <cfoutput group="product_id">

                        <cfoutput group="product_id">
                            {"id":#product_id#,"name":#product_name#,"price":#tlformat(price,2)#,"currency":#money#}
                        </cfoutput>
                    ]}

            <cfelse>
                {"status":"error"}
            </cfif>
        </pre>
    </body>
</html>

Answer 1

您需要将服务器代码设置为Content-Type: application/json标头，因此请使用the cfheader tag（链接用于CF 8）。例如：

<cfheader name="Content-Type" value="application/json">

服务器端响应是text / html
