Question

我是cocos2dx中的新手..我对json解析有些疑惑。我收到了来自服务器的消息。但我无法将消息发布到服务器。在这里我粘贴getmessages的代码。 Plz帮我发帖子。谢谢你。

void ChatRoom::function()
{

std::vector<std::string> headers;
headers.push_back("Content-Type: application/json; charset=utf-8");
cocos2d::extension::CCHttpRequest * request = new cocos2d::extension::CCHttpRequest();
request->setUrl("url here");

const char* postData ="chatManagerRequestType=GET_MESSAGES_AFTER_CHAT_ENABLED";


request->setRequestType(cocos2d::extension::CCHttpRequest::kHttpGet);
request->setResponseCallback(this, httpresponse_selector(ChatRoom::onHttpRequestCompleted));
request->setRequestData(postData, strlen(postData));
request->setHeaders(headers);
cocos2d::extension::CCHttpClient::getInstance()->send(request);
request->release();
}

void ChatRoom::onHttpRequestCompleted(cocos2d::CCNode *sender, void *data)
{

cocos2d::extension::CCHttpResponse * response = (cocos2d::extension::CCHttpResponse *)data;

if (!response)
{
    return;
}  std::string command;
if (0 != strlen(response->getHttpRequest()->getTag()))
{
    command = response->getHttpRequest()->getTag();
    CCLog("%s completed", response->getHttpRequest()->getTag());
}

int statusCode = response->getResponseCode();
char statusString[64] = {};
sprintf(statusString, "HTTP Status Code: %d, tag = %s", statusCode, response->getHttpRequest()->getTag());
CCLog("response code: %d", statusCode);

if (!response->isSucceed())
{
    CCLog("response failed");
    CCLog("error buffer: %s", response->getErrorBuffer());
    return;
}

std::vector<char> * buffer = response->getResponseData();

char * concatenated = (char *) malloc(buffer->size() + 1);
std::string s2(buffer->begin(), buffer->end());
strcpy(concatenated, s2.c_str());
CCLOG("%s",s2.c_str());
CCArray *arry=new CCArray();



printf("Http Test, dump data: ");
std::string tstr;
for (unsigned int i = 0; i < buffer->size(); i++)
{
    char s[10];
    sprintf(s, "%c",(*buffer)[i]);
    tstr += (*buffer)[i];
    arry->addObject((CCObject*)s);

}

for (int i=0; i<9; i++) {
    cocos2d::extension::Json * jsondd = cocos2d::extension::Json_create(concatenated);


    cocos2d::extension::Json *json1 = cocos2d::extension::Json_getItem(jsondd, "chatValueList");
    cocos2d::extension::Json *json2 = cocos2d::extension::Json_getItemAt (json1, 0);
    cocos2d::extension::Json *json3 = cocos2d::extension::Json_getItem(json2,"message");
    cocos2d::extension::Json *json31 = cocos2d::extension::Json_getItem(json2,"chatId");


    cocos2d::extension::Json *json4= cocos2d::extension::Json_getItem(json2,"userValue");
    cocos2d::extension::Json *json5= cocos2d::extension::Json_getItem(json4,"userName");
    cocos2d::extension::Json *json6= cocos2d::extension::Json_getItem(json4,"emailId");


    val1 = json5->valuestring;
    val2 = json3->valuestring;
    val3 = json31->valueint;


    CCLOG("value:%s   %s   %d",val1.getCString(),val2.getCString(),val3);


}

}

首先，要使用http发布数据，你必须使用kHttpPost而不是kHttpGet。因此，如果您只是将请求类型设置为CCHttpRequest :: kHttpPost，您就可以将您的发布数据发送到服务器。

其次，如果你没有遇到json的麻烦，那么就不要在问题标题中提及它。它误导了用户。
