cocos2dx之如何使用HttpClient进行网络通讯

#include "extensions/cocos-ext.h"
#include "network/httpClient.h”
using namespace cocos2d::network;

使用时的如下:

    httprequest* request1 = new httprequest();
    request1->setrequestType(httprequest::Type::GET);//这里是GET请求
    request1->setUrl("https://httpbin.org/get");
    request1->setResponseCallBACk(CC_CALLBACK_2(HelloWorld::onhttprequestCompleted,this));
    httpClient::geTinstance()->send(request1);
    request1->release();
        
    httprequest* request2 = new httprequest();
    request2->setUrl("http://httpbin.org/post");
    request2->setrequestType(httprequest::Type::POST);//这里是POST请求
    request2->setResponseCallBACk(CC_CALLBACK_2(HelloWorld::onhttprequestCompleted,this));
    // write the post data
    const char* postData = "visitor=cocos2d&TestSuite=Extensions Test/NetworkTest";
    request2->setrequestData(postData,strlen(postData));
    request2->setTag("POST test1");
    cocos2d::network::httpClient::geTinstance()->send(request2);
    request2->release();

https://httpbin.org/get

http://httpbin.org/post

本文是参考test中C++写的,test中也有lua版本的哦.

其中onhttprequestCompleted是响应的函数.我这里是参考官方的test写的,只是把数据在log输出.没有进行其他的处理

编辑响应的函数onhttprequestCompleted(),代码如下

void  HelloWorld::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());
    }
    
    long statusCode = response->getResponseCode();
    char statusString[64] = {};
    sprintf(statusString,"http Status Code: %ld,tag = %s",statusCode,response->gethttprequest()->getTag());
//    _labelStatusCode->setString(statusString);
    log("response code: %ld",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");
}
