Django 应用程序中的 API 调用问题

Question

我正在 Django 应用程序中进行简单的 API 调用，但遇到了一些问题

这里是ajax调用：

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

这里是调用 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)

这仅在每隔一次触发时才有效，一次失败然后一次成功。失败时不会捕获异常。以下是失败后输出窗口中显示的内容。

The thread 0x420 has exited with code 0 (0x0).

我已经在 postman 中测试了 URL，并且每次都收到响应，没有任何问题。

任何建议或想法将不胜感激。

Answer 1

设法查明真相。看起来页面正在重新加载并导致“ConnectionAbortedError”。

我将调用嵌套在一个需要

的 .submit 函数中

event.preventDefault();

最后添加。完整的工作代码现在看起来像这样。

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

);

希望这对其他人有所帮助:)
