Cocos2d HttpClient 用法

来源：互联网发布：双针探底公式源码编辑：程序博客网时间：2024/04/29 06:16

POST

    HttpRequest* request = new HttpRequest();
    request->setUrl("http://httpbin.org/post");
    request->setRequestType(HttpRequest::Type::POST);
    request->setResponseCallback(CC_CALLBACK_2(HelloWorld::onHttpRequestCompleted,this));

    // write the post data
    const char* postData = "visitor=cocos2d&TestSuite=Extensions Test/NetworkTest";
    request->setRequestData(postData, strlen(postData));
    request->setTag("POST test");
    cocos2d::network::HttpClient::getInstance()->send(request);
    request->release();

Get

   HttpRequest* request = new HttpRequest();
    request->setUrl("http://www.baidu.com");
    request->setRequestType(HttpRequest::Type::GET);
    request->setResponseCallback(CC_CALLBACK_2(HelloWorld::onHttpRequestCompleted,this));
    request->setTag("GET test");
    cocos2d::network::HttpClient::getInstance()->send(request);
    request->release();

CallBack 函数

必须头文件声明

#include "network/HttpClient"

using namespace cocos2d::network;

void onHttpRequestCompleted(HttpClient * sender,HttpResponse * response);

void ClassName:onHttpRequestCompleted(HttpClient *sender, HttpResponse *response)
{
    if (!response)
    {
        return;
    }

    // You can get original request type from: response->request->reqType
    if (0 != strlen(response->getHttpRequest()->getTag()))
    {
        log("%s completed", response->getHttpRequest()->getTag());
    }
    int statusCode = response->getResponseCode();
    char statusString[64] = {};
    sprintf(statusString, "HTTP Status Code: %d, tag = %s", statusCode, response->getHttpRequest()->getTag());
    log("response code: %d", statusCode);
    if (!response->isSucceed())
    {
        log("response failed");
        log("error buffer: %s", response->getErrorBuffer());
        return;
    }
    // dump data
    std::vector<char> *buffer = response->getResponseData();
    printf("Http Test, dump data: ");
    for (unsigned int i = 0; i < buffer->size(); i++)
    {
        printf("%c", (*buffer)[i]);
    }
    printf("\n");
}
