一、了解下x-www-form-urlencoded形式对于SAP来说有啥区别

简单来说,
1.raw格式就是标准的json格式:{“Name”:“John Smith”,“Age”: 23}
2.x-www格式是要转化一下的:Name=John+Smith&Age=23
字段与字段相互连接要用 & 符号,空格用 + 连接。所以说当你的关键参数里面带有这些特殊符号时,就要用方法转化一下。

二、具体实例。
先使用Postman跑一下,ok没有问题,可以通畅。关键信息按照你的接口来,我的接口信息上马了。

然后写ABAP代码:

DATA: len TYPEi, "发送报文长度len_stringTYPEstring,url TYPEstring, "接口地址http_client TYPE REF TO if_http_client, "http客户端post_string TYPEstring,resultTYPEstring.DATA: it_headerTYPE tihttpnvp,gv_json_in TYPE string VALUE '' .START-OF-SELECTION." url = 'https://api.map.baidu.com/weather/v1/" />.url = 'http://这是个具体的网址,你需要粘贴上你的网址token'.cl_http_client=>create_by_url(EXPORTING url = url"服务提供方服务地址IMPORTING client=DATA(lo_client))."调取方式:get 或者为 postlo_client->request->set_method( if_http_request=>co_request_method_post )." lo_client->request->set_method( if_http_request=>co_request_method_get )."设置抬头字段CALL METHOD lo_client->request->set_header_fieldEXPORTINGname= 'Content-Type'value = 'application/x-www-form-urlencoded'."为这种形式的,需要设置抬头格式"返回格式。为json的lo_client->response->if_http_entity~set_content_type( content_type = 'application/json' ).*lo_client->response->get_header_field( name = 'x-csrf-token' ).*lo_client->response->get_cookies( CHANGING cookies = lt_cookies ).DATA:lv_username TYPE string.DATA:lv_password TYPE string."为这种x-www-form-urlencoded形式的,需要把变量全部转译一下,比如&符号的lv_username = cl_http_utility=>escape_url( 'cha填写关键信息' ).lv_password = cl_http_utility=>escape_url( 'O0&J人工打码' ).gv_json_in = 'grant_type=password' && "固定值 '&username=' && lv_username && '&password=' && lv_password && '&client_id=crm' ."固定值DATA(lv_len) = strlen( gv_json_in ).**设置post接口body参数lo_client->request->set_cdata( data = gv_json_inlength = lv_len ).**发送数据lo_client->send("EXPORTING " timeout= co_timeout_default " Timeout of Answer Waiting TimeEXCEPTIONShttp_communication_failure = 1" Communication Errorhttp_invalid_state = 2" Invalid statehttp_processing_failed = 3" Error When Processing Methodhttp_invalid_timeout = 4" Invalid Time EntryOTHERS = 5).IF sy-subrc <> 0.result = '接口接受响应失败'.ENDIF.************************************************************************接收返回参数lo_client->receive(EXCEPTIONShttp_communication_failure = 1" Communication Errorhttp_invalid_state = 2" Invalid statehttp_processing_failed = 3" Error When Processing MethodOTHERS = 4).IF sy-subrc  0.result = '接口接受响应失败'.ENDIF.result = lo_client->response->get_cdata( ).lo_client->close( )."WRITE: url.WRITE: / result.

DEBUG看下过程,发现&符号是已经转义了

然后调取成功。
