我试图模仿function Base() {
this.type = "base";
}
Base.prototype = {
clone: function () {
var c = new this.constructor();
// let clone initialize itself from the original
c.init(this);
return c;
},
setName: function(name) {
this.name = name;
},
init: function(obj) {
// copy over name instance data
this.name = obj.name;
}
}
// set .constructor property for use with .clone()
Base.prototype.constructor = Base;
function Derived() {
Base.call(this);
this.type = "derived";
}
// inherit from Base
Derived.prototype = Object.create(Base.prototype);
Derived.prototype.setOccupation = function(occupation) {
this.occupation = occupation;
}
Derived.prototype.init = function(obj) {
// let base object init itself
Base.prototype.init.call(this, obj);
// copy over our own instance data
this.occupation = obj.occupation;
}
// set .constructor property for use with .clone()
Derived.prototype.constructor = Derived;
var x = new Derived();
x.setName("Bob");
x.setOccupation("Engineer");
var xx = x.clone();
var y = new Base();
y.setName("Alice");
var yy = y.clone();
log(x !== xx)
log(x);
log(xx);
log(y);
log(yy)
// function just for output in snippet
function log(a) {
var div = document.createElement("div");
if (typeof a === "object") {
a = JSON.stringify(a);
}
div.innerHTML = a;
document.body.appendChild(div);
}的行为。我正在发送一个带有以下json有效负载的HTTP PATCH：
kubectl patch然而，无论我如何调整这个JSON，我都会继续获得415和以下JSON状态：
{
"apiVersion": "v1",
"kind": "Node",
"metadata": {
"name": "my-node-hostname"
},
"spec": {
"unschedulable": true
}
}
即使将kube-apiserver上的调试设置为1000，我也没有得到有关有效负载错误原因的反馈！
是否应该在通过PATCH发送的JSON有效负载中使用特定格式以使其能够正常工作？
答案 0 :(得分：2)
在提到Kubernetes Slack频道的有用成员后，我可以通过--verbose标志从kubectl patch获取有效负载，结果发现Kubernetes希望在发送PATCH时获得"Content-Type: application/strategic-merge-patch+json"有效载荷。
