Step1 建立對應的 Parse App 並設定好對應的資料格式
本範例為 testRest
Step2 導入網路所需對應的header檔案
#include "network/HttpClient.h"
using namespace cocos2d::network;
Step3 使用 HttpRequest 設定 Parse 存取的權限
需要使用圖中的 Application ID 以及 Rest API Key
範例：
HttpRequest* request = new HttpRequest();
request->setRequestType(HttpRequest::Type::POST);
request->setUrl("https://api.parse.com/1/classes/sampleTable");
vector<string> header;
header.push_back("X-Parse-Application-Id: wCq2Ojdxj0aNdccb94sSr6Ke3uryqsO6spkkZKkd");
header.push_back("X-Parse-REST-API-Key: Vp6OGjqqV1XNAbmRWzL2EylDVFs0TeULO5EQDDSR");
header.push_back("Content-Type: application/json");
request->setHeaders(header);
Step4 Parse中表單欄位設定
// Post 建立表單資料
auto data = "{\"ColNum\":100, \"ColString\":\"ABC\"}";
const char * buffer = data;
request->setRequestData(buffer, strlen(buffer));
request->setResponseCallback(CC_CALLBACK_2(HelloWorld::onHttpRequestPostCompleted, this));
cocos2d::network::HttpClient::getInstance()->send(request);
request->release();
Step5 資料回傳函式設定, Post 完成
void HelloWorld::onHttpRequestPostCompleted(HttpClient* sender, HttpResponse* response)
{
if (response->isSucceed()) {
CCLOG("Post success");
}
}
Get 設定
HttpRequest* getRequest = new HttpRequest();
getRequest->setUrl("https://api.parse.com/1/classes/sampleTable/x9luwPXvGT");
getRequest->setHeaders(header);
getRequest->setRequestType(HttpRequest::Type::GET);
getRequest->setResponseCallback(CC_CALLBACK_2(HelloWorld::onHttpRequestGetCompleted, this));
HttpClient::getInstance()->send(getRequest);
getRequest->release();
Get 回傳 Json 格式, 使用rapidjson分析資料
- 導入標頭檔
#include "json/rapidjson.h" #include "json/document.h"void HelloWorld::onHttpRequestGetCompleted(HttpClient* sender, HttpResponse* response) { if (response->isSucceed()) { CCLOG("Get success"); std::vector<char>* buffer = response->getResponseData(); std::string res; res.insert(res.begin(), buffer->begin(), buffer->end()); rapidjson::Document d; d.Parse<0>(res.c_str()); printf("%s\n", d["ColString"].GetString()); } }
