Question

我已经完成使用ipstack.com设置ip到地理位置的所有步骤，并通读了documentation。但是对象值在我的浏览器控制台中返回为“ undefined”。代码是这样的：

var ip = '188.124.3.1';
var access_key = 'secret';
$.ajax({
    url: 'https://api.ipstack.com/' + ip + '?access_key=' + access_key,   
    dataType: 'jsonp',
    success: function(json) {
        var city = json.city;
        var zip = json.zip;
        var latitude = json.latitude;
        var longitute = json.longitute;
        console.log(city + ' ' + zip + ' ' + latitude + ' ' + longitute);
        console.log('success!');
        //the code reaches this stage, but returns as 'undefined' for each value above
        //execute a second ajax function to insert the values into a database.
        $.ajax({
            type: "post",
            url: "insert_geolocation.php",
            data: {
                    'zip': zip,
                    'lat': latitude,
                    'lng': longitute
                    },
            success: function (data) {
                // it's successful, do nothing else.
                // the code also reaches this stage, but the database gets a row with NULL and 0 as values...So the response from the API is returning undefined, for an unknown reason.
            },
        });
    },
    error: function(html, data) {
        console.log('Error!');
        console.log(data);
    }
});

我正在使用jQuery和文档中的JSON输出，因为我并没有真正了解CURL。谁能确切告诉我为什么会这样？

此问题的解决方案是因为我处于免费订阅计划中，并且不提供通过“ ssl”进行访问的计划。只需像这样打印json：在成功函数内==25999== Conditional jump or move depends on uninitialised value(s) ==25999== at 0x4ECC374: _IO_str_init_static_internal (strops.c:51) ==25999== by 0x4EBD6C2: vsprintf (iovsprintf.c:41) ==25999== by 0x4EA1093: sprintf (sprintf.c:32) ==25999== by 0x4008E7: read_data ==25999== by 0x400B80: main ==25999== Uninitialised value was created by a heap allocation ==25999== at 0x4C2FB0F: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==25999== by 0x400898: read_data ==25999== by 0x400B80: main，然后查看它会给您带来什么错误。

Ipstack响应为“未定义”，并且文档未解释原因？
