Odoo V11 restapi - TypeError(repr(o) + “不是 JSON 可序列化”)

Question

我正在使用 odoo v11 与 restapi 集成，尽管在获取错误报告数据时在 CRUD 操作中工作正常

file.py

 def generate_report(self, xml_id, ids):
    self_reports = {}
    self_reports = {'result': False, 'state': False, 'exception': None}
    try:
        result, format = request.env.ref(xml_id).sudo().render_qweb_pdf([ids])
        if not result:
            tb = sys.exc_info()
            self_reports['exception'] = odoo.exceptions.DeferredException('RML is not available at specified location or not enough data to print!', tb)
        self_reports['result'] = result
        self_reports['format'] = format
        self_reports['state'] = True
        self_reports.update({'id': ids})
    except Exception as exception:
        _logger.exception('Exception: %s\n', exception)
        if hasattr(exception, 'name') and hasattr(exception, 'value'):
            self_reports['exception'] = odoo.exceptions.DeferredException(tools.ustr(exception.name), tools.ustr(exception.value))
        else:
            tb = sys.exc_info()
            self_reports['exception'] = odoo.exceptions.DeferredException(tools.exception_to_unicode(exception), tb)
        self_reports['state'] = True

    exc = self_reports['exception']
    if exc:
        raise UserError('%s: %s' % (exc.message, exc.traceback))
    if self_reports['state']:    
        if tools.config['reportgz']:
            import zlib
            res2 = zlib.compress(result)
        else:
            if isinstance(result, str):
                res2 = result.encode('latin1', 'replace')
            else:
                res2 = result
        if res2:
            self_reports['result'] = base64.encodestring(res2)
    return self_reports

def get_response(self, status_code, status, data=None):
    """Returns Response Object with given status code and status"""
    response = Response()
    response.status = status
    if data:
        response.data = isinstance(data, str) and data or json.dumps(data)
    response.status_code = status_code
    return response

这是数据格式

list: [{'exception': None, 'state': True, 'id': 3, 'format': 'pdf', 'result':

错误回溯：

return self.get_response(200, str(200), {'report': datas})

我需要 api 响应中二进制数据的 pdf 报告，响应数据中出现错误。请任何人帮我解决这个问题

这是因为您可能忘记了import json lib。在您的标头中声明 import json 这可能会帮助您解决错误。
