Django应用程序

我正在Django应用程序中进行简单的API调用，但我遇到了一些问题

这是ajax调用：

$.ajax({
    type: "GET",
    url: "/query/",
    success: function (data) {
        alert(data);
    }
});

以下是调用API的函数：

def query(request):
    response = requests.get("http://api.open-notify.org/iss-now.json")
    return JsonResponse(response.status_code, safe=False)

这只会在每次触发时起作用，一次失败然后一次成功。失败时没有捕获异常。以下是失败后在输出窗口中显示的内容。

我已经在邮递员中测试了网址，并且每次都没有问题就收到了回复。

感谢任何建议或想法。

掌握了它的底部。看起来页面正在重新加载并导致＆＃34; ConnectionAbortedError＆＃34;。

我将调用嵌套在.submit函数中，该函数需要

// MyViewController.swift
override func viewDidLoad() {
        super.viewDidLoad()
        let algorithm = GMUNonHierarchicalDistanceBasedAlgorithm()
        let renderer = GMUDefaultClusterRenderer(mapView: self.mapView, clusterIconGenerator: iconGenerator)
        renderer.delegate = self
        self.clusterManager = GMUClusterManager(map: self.mapView, algorithm: algorithm, renderer: renderer)

        for (index, marker) in markers.enumerated() {
            let markerItem = POIItem(position: marker.position, name: "Marker \(index)")
            self.clusterManager.add(markerItem)
        }
        self.mapViewContainer.addSubview(self.mapView)
        clusterManager.cluster()
    }

func renderer(_ renderer: GMUClusterRenderer, willRenderMarker marker: GMSMarker) {
        let pinImageView = UIImageView(image: #imageLiteral(resourceName: "pin"));
        let iconView = UIView(frame: CGRect(x: 0, y: 0, width: pinImageView.frame.width, height: pinImageView.frame.height))
        iconView.clipsToBounds = false

        iconView.backgroundColor = .clear
        iconView.addSubview(pinImageView)
        iconView.layoutIfNeeded()

        if let markerData = marker.userData {
            if let markerClusterData = (markerData as? GMUCluster) {
                let totalLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
                let labelContainerView = UIView(frame: CGRect(x: 20, y: -10, width: 25, height: 25))
                labelContainerView.backgroundColor = #colorLiteral(red: 0.9803921569, green: 0.7058823529, blue: 0.1176470588, alpha: 1)
                totalLabel.font = totalLabel.font.withSize(12.0)
                totalLabel.text = "\(markerClusterData.count)+"
                totalLabel.textAlignment = .center
                totalLabel.textColor = .white
                labelContainerView.addSubview(totalLabel)
                labelContainerView.layer.cornerRadius = 12.5
                labelContainerView.layoutIfNeeded()
                iconView.addSubview(labelContainerView)
                iconView.bounds = iconView.frame.union(labelContainerView.frame)
            }
        }

        marker.iconView = iconView
    }
// Default POIITem implementation, exactly like Google teaches.
class POIItem: NSObject, GMUClusterItem {
    var position: CLLocationCoordinate2D
    var name: String!

    init(position: CLLocationCoordinate2D, name: String) {
        self.position = position
        self.name = name
    }
}

最后添加。完整的工作代码现在看起来像这样。

event.preventDefault();

希望这有助于其他人下线：）
