I use CCHttpClient to develop webservice program,
I already use CCHttpClient to test CreateMember function is ok,

After adding csrf_token verification on php CreateMember,
I test ok on web browser,
but use CCHttpClient to test on ios device,
I get HttpStatus code 500.

This is php csrf code below:
Route::put(‘member/webupdate’, array(‘before’=>‘csrf’, ‘uses’=>‘members@webupdate’));

Can anybody help me how to fix verify fail.

This is client code below:

CCHttpRequest* request = new CCHttpRequest();

//list all, wait terry to provide multiUser,he need create New table&implement php
char url[256];
sprintf(url, “sPojectName/public/members/create",hostName.c_str());
request->setUrl(url);
request->setRequestType(CCHttpRequest::kHttpPost);
request->setResponseCallback(pTarget, pSelector);

char postData[512];
sprintf(postData,"u\_id=d&csrf\_token=%s”,

0,
certificate.c_str());
request~~>setRequestData);
request~~>setTag(“createNewUserRequest”);
//CCLog(postData);

CCHttpClient::getInstance()>send;
request>release();
