Javascript source code:
<html> <head> <script type="text/javascript"> var xmlhttp; function GetXmlHttpObject() { if (window.XMLHttpRequest) { return new XMLHttpRequest(); } if (window.ActiveXObject) { return new ActiveXObject("Microsoft.XMLHTTP"); } return null; } function stateChanged() { if (xmlhttp.readyState == 4) { document.getElementById("result").innerHTML = xmlhttp.responseText; document.getElementById("result").style.border = "1px solid #A5ACB2"; } } function getRequestURL(str) { var url = <use your own url here>+ str; url = url + "&sid=" + Math.random(); return url; } function showResult(str) { if (str.length == 0 ) { document.getElementById("result").innerHTML = ""; document.getElementById("result").style.border = "0px"; return; } xmlhttp = GetXmlHttpObject(); if (xmlhttp == null ){ alert ("Your browser does not support XML HTTP Request"); return; } var requesturl = getRequestURL(str); xmlhttp.onreadystatechange = stateChanged ; if ("withCredentials" in xmlhttp) { console.log("Great!!!!!"); } xmlhttp.open("POST",requesturl,true); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); var data = []; data.push( escape("firstname=Jerry 1")); data.push( escape("lastname=Wang 2")); xmlhttp.send(data.join("&")); } </script> </head> <body> <input type="text" id="fname" onkeyup="showResult(this.value)" /> <div id = "result" ></div> </body> </html>
设置Content-Type为form-urlencoded, 即需要通过http post发送到server端的数据通过name-value pair的形式加到post url中去。
在ABAP 端能够成功还原出发送的firstname和lastname的数据:如果content type改成text/plain:
xmlhttp.setRequestHeader("Content-Type", "text/plain"); var data = []; data.push( escape("firstname=Jerry 1")); data.push( escape("lastname=Wang 2")); xmlhttp.send(data.join("\r\n"));
此时firstname和lastname只能通过request->get_cdata() 来读取:
server->request->get_header_fields( CHANGING fields = lt_header ). server->request->get_form_fields( CHANGING fields = lt_form ). lv_data = server->request->get_cdata( ). SPLIT lv_data AT cl_abap_char_utilities=>cr_lf INTO TABLE lt_result.
Chrome里出现的位置从Form Data 改成了Request payload:
