PHP-implemented registration, login, and query of user information function API example, user information api

This example describes the API interface for registering, logging on to, and querying user information implemented by PHP. We will share this with you for your reference. The details are as follows:

Server

<? Phprequire 'conn. php '; header ('content-Type: text/html; charset = UTF-8'); $ action = $ _ GET ['action']; switch ($ action) {// registered member case "adduserinfo"; $ username = lib_replace_end_tag (trim ($ _ GET ['username']); $ password2 = lib_replace_end_tag (trim ($ _ GET ['userpassword']); $ password = md5 ("$ password2 ". ALL_PS); $ email = lib_replace_end_tag (trim ($ _ GET ['email ']); if ($ username = ''| $ password2 ='' | $ pass Word = '') {$ res = urlencode (" parameter error "); exit (json_encode ($ res )); // available information} $ SQL = "select username from 'member' where username = '$ username'"; $ query = mysql_query ($ SQL, $ conn ); $ count = mysql_num_rows ($ query); if ($ count> 0) {exit (json_encode (1 )); // return 1 indicating registration Failed} else {$ addsql = "insert into 'member' (username, password, email) values ('$ username',' $ password ', '$ email') "; mysql_query ($ addsql); exit (j Son_encode (0); // return 0 indicates successful registration} break; // query User Information case "selectuserinfo "; $ username = lib_replace_end_tag ($ _ GET ['username']); $ SQL = "select id, username, nickname, mobile from 'member' where username = '$ username '"; $ query = mysql_query ($ SQL, $ conn); $ row = mysql_fetch_array ($ query); foreach ($ row as $ key => $ v) {$ res [$ key] = urlencode ($ v);} exit (json_encode ($ res); break; // member logon case "userlogin"; $ usernam E = lib_replace_end_tag ($ _ GET ['username']); $ password2 = lib_replace_end_tag (trim ($ _ GET ['userpassword']); $ password = md5 ("$ password2 ". ALL_PS); $ sqluser = "select id, username, password from 'member' where username = '". $ username. "'and password = '". $ password. "'"; $ queryuser = mysql_query ($ sqluser); $ rowuser = mysql_fetch_array ($ queryuser); if ($ rowuser & is_array ($ rowuser )&&! Empty ($ rowuser) {if ($ rowuser ['username'] = $ username & $ rowuser ['Password'] = $ password) {if ($ rowuser ['Password'] = $ password) {$ res = urlencode ("Logon successful"); exit (json_encode ($ res ));} else {$ res = urlencode ("Incorrect password"); exit (json_encode ($ res) ;}} else {$ res = urlencode ("the user name does not exist "); exit (json_encode ($ res) ;}} else {$ res = urlencode ("incorrect user name and password"); exit (json_encode ($ res);}/** 0: indicates that the logon is successful. 1: indicates that the password is incorrect. Error: 2: the user name does not exist; 3: the user name and password are incorrect */break; default: exit (json_encode (error);}?>

Client example:

<? Phpheader ('content-Type: text/html; charset = UTF-8 '); // avoid output garbled function httpPost ($ url, $ parms) {$ url = $ url. $ parms; if ($ ch = curl_init ($ url) = false) {throw new Exception (sprintf ("curl_init error for url % s. ", $ url);} curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ ch, CURLOPT_HEADER, 0); curl_setopt ($ ch, CURLOPT_CONNECTTIMEOUT, 600 ); curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1); if (Is_array ($ parms) {curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ('content-Type: multipart/form-data ;'));} $ postResult = @ curl_exec ($ ch); $ http_code = curl_getinfo ($ ch, CURLINFO_HTTP_CODE); if ($ postResult = false | $ http_code! = 200 | curl_errno ($ ch) {$ error = curl_error ($ ch); curl_close ($ ch); throw new Exception ("http post failed: $ error ");} else {// $ postResult = str_replace (" \ xEF \ xBB \ xBF ",'', $ postResult); switch (curl_getinfo ($ ch, CURLINFO_CONTENT_TYPE) {case 'application/json': $ postResult = json_decode ($ postResult); break;} curl_close ($ ch); return $ postResult ;}}$ postUrl = "http://pujia.test.com/api/server.ph P "; $ p = $ _ GET ['P']; if ($ p =" selectuserinfo ") {$ username = $ _ GET ['username']; $ parms = "? Action = selectuserinfo & username = ". $ username. "";} elseif ($ p = "adduserinfo") {$ username = $ _ GET ['username']; $ userpassword = $ _ GET ['userpassword']; $ parms = "? Action = adduserinfo & username = ". $ username. "& userpassword = ". $ userpassword. "";} elseif ($ p = "userlogin") {$ username = $ _ GET ['username']; $ userpassword = $ _ GET ['userpassword']; $ parms = "? Action = userlogin & username = ". $ username. "& userpassword = ". $ userpassword. "" ;}$ res = httpPost ($ postUrl, $ parms); // $ parms $ res = json_decode ($ res ); print_r (urldecode (json_encode ($ res);?>

Note:In the codelib_replace_end_tagThe function is a custom string filter function. For details, refer to: analysis of how php filters html strings to prevent SQL injection.
