jQuery Ajax 问题

Question

我想弄清楚我在这里做错了什么。基本上我试图从以下位置获得成功的回调:

http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer/project?f=pjson&inSR=4326&outSR=102113&geometries={"geometryType":"esriGeometryPoint","geometries":[{"x":-117,"y":34}]}

将其粘贴到浏览器中时，我会获取数据，但当我在 Javascript 中执行此操作时，它不起作用，因为它会调用错误处理程序。有任何想法吗？我用fiddler比较了请求，发现确实没有区别。

$.ajax({
    type: 'GET',
    url: 'http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer/project?f=pjson&inSR=4326&outSR=102113&geometries={"geometryType":"esriGeometryPoint","geometries":[{"x":-117,"y":34}]}',
    success:    function(data){ 
        alert('success');
    },
    error: function(jqXHR, textStatus, errorThrown){
        alert('error');
    }   
});

添加json参数:

$.ajax({
    type: 'GET',
    dataType : 'jsonp',
    url: 'http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer/project?f=pjson&inSR=4326&outSR=102113&geometries={"geometryType":"esriGeometryPoint","geometries":[{"x":-117,"y":34}]}',
    success:    function(data){ 
        alert('success');
    },
    error: function(jqXHR, textStatus, errorThrown){
        alert('error');
    }   
});
