问题排查及修复方案 #

• 添加/修正SOAPAction请求头
  Sabre SOAP API要求必须携带正确的SOAPAction请求头，针对OTA_AirRulesRQ接口，正确值为"http://webservices.sabre.com/sabreXML/2011/10/OTA_AirRulesRQ"。在Postman的请求头列表中新增该字段，确保值与请求体中的命名空间完全匹配。

• 修正日期格式
  请求中FlightSegment的DepartureDateTime仅填写了12-24，缺少年份，不符合Sabre的格式要求，需改为完整日期格式，例如2024-12-24。

• 清理安全令牌空白字符
  当前请求中BinarySecurityToken的值后存在换行和空格，可能导致令牌验证异常，请删除多余空白，确保令牌值紧凑无换行。

• 验证命名空间与版本兼容性
  确认OTA_AirRulesRQ的命名空间http://webservices.sabre.com/sabreXML/2011/10和版本2.3.0为Sabre当前支持的有效组合，若版本过时需更换为最新兼容版本。
