Question

我使用flask 0.12，并尝试使用ajax发送PUT请求。但是，使用.get_json()方法时，我收到错误消息无法解码JSON对象。内容为json，is_json返回True。有我的客户端代码：

$.ajax({
    url: apiTechnicians,
    type: 'PUT',
    data: { "technicianUserId": chosenTechnician.val() },
    contentType: "application/json",
    dataType: "json",
    success: function (result) {
        console.log(result)
    }
});

还有服务器端代码：

@api.route("/technicians", methods=['PUT'])
def putTechnicians():
    print request.is_json
    jsonResult = request.get_json()
    return Response(status=200)

有什么建议我应该如何处理接收到的数据以及为什么get_json()无法解码数据？

您不是在发送JSON，而是在说它的json（通过内容类型），但不是。
jQuery.ajax将传递给它的对象转换为Private Sub DetailsButton_Click() Me.Details.Visible = True End Sub数据，因此要发送json数据，必须将json数据传递给jQuery.ajax
