我正在向 Jersey Resource 发布 AJAX 帖子。我建立一个图像并返回它。问题是,无论我返回什么状态,Ajax 都认为这是一个错误。我实际上可以使用错误消息(通过error.responseTest),它工作正常。但它很丑。我要返回什么才能使它成功?我已返回 OK(200)、Accepted(202) 和 Created(201)。他们都给我一条错误消息,但在我的控制台网络选项卡中,我得到了成功(绿色,状态正确)。
我像这样返回它:
return Response.status(Response.Status.ACCEPTED).entity(image).header('Content-Type',"image/png").build();
我的 JS 代码:
$.ajax( Monocle.config.Sightline.jobUrl + "/sightline", {
type: "POST",
processData: false,
data: JSON.stringify({
Lat1: Monocle.Sightline.BBOX(feature,2),
Long1: Monocle.Sightline.BBOX(feature,1),
Lat2: Monocle.Sightline.BBOX(feature,4),
Long2: Monocle.Sightline.BBOX(feature,3),
OrgLat:observerCoords[0].lat,
OrgLong:observerCoords[0].lon,
ObHeight: feature.attributes.observerHeight,
TargHeight: feature.attributes.targetHeight,
OuterRadius: feature.attributes.outerRadius,
LVA: feature.attributes.lowerVertAngle,

outputType: "MAX"
}),
contentType: "application/json",
dataType: "json",
success: function( results ){
var graphic = new OpenLayers.Layer.Image(
Monocle.currentWidget.name + " Destination " + featurenum,
"data:image/png;base64," + results,
new OpenLayers.Bounds(Monocle.Sightline.BBOX(feature,1), Monocle.Sightline.BBOX(feature,2), Monocle.Sightline.BBOX(feature,3),Monocle.Sightline.BBOX(feature,4)),
new OpenLayers.Size(580, 288),
{ isBaseLayer: false,
opacity: 0.3,
displayOutsideMaxExtent: true
});
feature.legionObject = graphic;
graphic.relatedlayer = Monocle.currentWidget.name + " Destination " + featurenum;
Monocle.Map.map.addLayer(graphic);
},
error: function(errMsg) {
// TODO: really handle any errors
}
});
