    The request parameter can be a HttpEntity in order to add additional HTTP headers to the request.
    NOTE: The standard JDK HTTP library does not support HTTP PATCH. You need to use the Apache HttpComponents or OkHttp request factory.
    参数:
    url - the URL
    request - the object to be PATCHed (may be null)
    responseType - the type of the return value
    返回:
    the converted object
