doris _stream_load There is no 100-continue header 报错解决

问题：
{“status”:“FAILED”,“msg”:“There is no 100-continue header”}

解决：
request headers增加参数即可：“expect”: “100-continue”

完整headers示例：
headers = {
“Content-Type”: “application/json”,
“strict_mode”: “false”,
“format”: “json”,
“read_json_by_line”: “true”,
“expect”: “100-continue”,
“unique_key_update_mode”: “UPDATE_FLEXIBLE_COLUMNS”,
“Authorization”: f"Basic {base64.b64encode(f’{DORIS_USER}:{DORIS_PASSWORD}'.encode()).decode()}"
}
