Without seeing the JSON Response i would have to guess, that the Problem is, that you are using the Wrong(or no) Quotes for the JSON. You must use doubleQuotes(for property names and string values), or at least when i had that problem, the double quotes solved it.
如果没有看到 JSON 响应，我将不得不猜测，问题是您对 JSON 使用了错误的（或没有）引号。您必须使用双引号（用于属性名称和字符串值），或者至少当我遇到这个问题时，双引号解决了它。
Example:
例子：
{"id":1,"name":"TOM"}
i hope this helps.
我希望这有帮助。

For other friends that have such an error, try to return a JSON value to the page that you send your values from.
对于其他出现此类错误的朋友，请尝试将 JSON 值返回到您发送值的页面。
In my case, I'm on localhost:8080/senderpage that sends JSON data to localhost:8110/receiverpage. After receiver page gets the data, return something like {}back to the sender page. Otherwise, the error callback is called even if the server returns a 200 HTTP code.
就我而言，我在localhost:8080/sender将 JSON 数据发送到localhost:8110/receiver页面的页面上。接收者页面获取数据后，返回类似于{}发送者页面的内容。否则，即使服务器返回 200 HTTP 代码，也会调用错误回调。
