问题似乎是curl将其他查询参数（turn，id，auth_key）理解为https://api.telegram.org的参数，而不是您在url参数中传递的url的参数。

curl -X POST https://httpbin.org/anything -d "url=https://example.com/control?channel=X&turn=XXX&id=XXXXXX&auth_key=XXXXX"

返回的对象包含：

"form": {
    "auth_key": "XXXXX",
    "id": "XXXXXX",
    "turn": "XXX",
    "url": "https://example.com/control?channel=X"
},

解决方案是使用--data-urlencode标志，而不是-d（即--data）：

curl -X POST "https://httpbin.org/anything" --data-urlencode "url=https://example.com/control?channel=X&turn=XXX&id=XXXXXX&auth_key=XXXXX"

回复：

"form": {
    "url": "https://example.com/control?channel=X&turn=XXX&id=XXXXXX&auth_key=XXXXX"
},

电报请求：

curl -X POST https://api.telegram.org/bot<telegram_token>/setWebhook --data-urlencode "url=https://example.com/control?channel=X&turn=XXX&id=XXXXXX&auth_key=XXXXX"
