DATA: http_client TYPE REF TO if_http_client.

  "URL填全部，带参数
  CALL METHOD cl_http_client=>create_by_url
    EXPORTING
      url    = 'https://www.baidu.com'
    IMPORTING
      client = http_client.

  http_client->propertytype_logon_popup = http_client->co_enabled .
  http_client->propertytype_redirect = http_client->co_disabled .

  CALL METHOD http_client->request->set_header_field
    EXPORTING
      name  = '~request_method'
      value = 'GET'.

  CALL METHOD http_client->request->set_header_field
    EXPORTING
      name  = '~request_protocol'            "http请求则改为'~service_protocol'
      value = 'HTTPS/1.1'.                "'HTTP/1.1'

  CALL METHOD http_client->request->set_header_field
    EXPORTING
      name  = 'Content-Type'
      value = 'text/html'. " text/html 看情况填application/json

*  "set body
*  CALL METHOD HTTP_CLIENT->REQUEST->SET_CDATA
*    EXPORTING
*      DATA   = LV_PARAM
*      OFFSET = 0
*      LENGTH = LV_LEN.

  CALL METHOD http_client->send
    EXCEPTIONS
      http_communication_failure = 1
      http_invalid_state         = 2.
  CALL METHOD http_client->receive
    EXCEPTIONS
      http_communication_failure = 1
      http_invalid_state         = 2
      http_processing_failed     = 3.

* 获取返回的数据
  DATA: r_value    TYPE string,
        r_value1   TYPE string,
        r_fields   TYPE tihttpnvp,
        r_h_fields TYPE tihttpnvp.
    http_client->response->get_header_fields( CHANGING fields =  r_h_fields ).

注意：
1.url必须带"http://"或者“https://”。
2. http_client->propertytype_redirect = http_client->co_disabled .这一行是设置是否允许重定向，是为“co_enabled”，否为“co_disabled”。
3. 可能出现的错误 404 Hostname Unknow，是因为服务器未配置该url的dns
4. 可能出现的错误 401 refused，可能是被防火墙挡住了，以上两个问题可以找basis协助解决文章来源地址https://www.toymoban.com/news/detail-723198.html
