UTL_HTTP read_text和read_raw應用

response數據量小

read_line或者 read_text

示例：

?l_http_request???UTL_HTTP.REQ;

??l_http_response??UTL_HTTP.RESP;

???BUFFER??VARCHAR2(32767);

??l_response_clob??CLOB;

????xml XMLTYPE;

BEGIN

????...

????l_http_response := UTL_HTTP.GET_RESPONSE(l_http_request);

???DBMS_LOB.CREATETEMPORARY(l_response_clob, TRUE, DBMS_LOB.CALL);

???DBMS_LOB.OPEN(l_response_clob, DBMS_LOB.LOB_READWRITE);

????BEGIN

????LOOP

???????UTL_HTTP.READ_TEXT(l_http_response, BUFFER, 32767);

???????DBMS_LOB.WRITEAPPEND(l_response_clob, LENGTH(BUFFER), BUFFER);

????END LOOP;

????EXCEPTION

???????WHEN UTL_HTTP.END_OF_BODY THEN

??????????UTL_HTTP.END_RESPONSE(l_http_response);

????END;

???DBMS_LOB.CLOSE(l_response_clob);

????xml := XMLTYPE(l_response_clob);

????... do whatever you need with XML docuemnt

???DBMS_LOB.FREETEMPORARY(l_response_clob);

END;

response數據量很大

建議使用read_raw

示例?

???dbms_lob.createtemporary( blob_buf, true );

????http_resp:= utl_http.get_response(http_req);

--

????begin

?????loop

???????utl_http.read_raw( http_resp, raw_buf );

???????dbms_lob.append( blob_buf, raw_buf );

??????end loop;

????exception

??????when utl_http.END_OF_BODY

?????then

???????null;

????end;

????utl_http.end_response( http_resp );
