根据维基百科的List of HTTP status codes :

400 Bad Request

The server cannot or will not process the request due to an apparent client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).[36]

通俗地说，data是无效的:

var data = {
  "user" : {
    "name": user.name,
    "email": user.email,
    "phone": "+91"+ user.phone,
    "password": user.password,
    "address": user.address
  }
};

当服务器尝试处理 data 时，它检测到 data 无效并发送 400。

以下是一些可能的原因:

• data 缺少必需的值
• data.phone 无效
• data.address 无效
• data.password 无效(可能是太弱了...？)
• 缺少一个重要的请求 header

您应该检查data 的格式是否符合服务器的要求。

您还应该检查响应正文，看它是否包含更具体的错误。
