http通讯问题

Cocos2d-x Lua
#1

local request = network.createHTTPRequest(handler(self,self._onRecieve), url, “POST”)
request:addPOSTValue(“data”, data)
request:start()
print(“send------------------->”,msgname)

游戏用http通讯，其他消息都么有问题，只有一条消息每次都报这个错，想跟进代码看都不知道去哪看，求大神帮帮忙~
_onRecieve方法有的时候能执行到 event.name == “completed” 并且request:getResponseStatusCode() == 200，有的时候执行不到

是哪个版本 你对 event.name ~= "completed"做了处理没？

#3

帮顶！:2:

#4

没有做处理 跟服务端调了一下 以aascii码的形式打印出消息 好像是消息在一个地方因为有个0被截断了 不知道咋回事~

#5

版本是2.1.5的

#6

升级到2.2.5版本 如果不想升级直接拷贝底层 CCHTTPRequest.h 和 CCHTTPRequest.cpp这2个文件到你的2.1.5中，再看看。

#7

说错了~ 是2.2.5 release版本的

#8

event complete 的时候，并不一定 status == 200

解决的办法，是来一下服务返回的 http 头看一下

你可以看看下面的回调代码

innerCallback = function(event)
printf(" event:" … tostring(event.name))
local response = event.request
local statusCode
if event.name == “failed” then
statusCode = -1
else
statusCode = response:getResponseStatusCode()
end
printf(" event:" … tostring(event.name) … “, status:” … tostring(statusCode))
if event and event.name == “completed” then
if statusCode == 200 then
callback(nil, response:getResponseData())
else
callback(“bad server response. status:” … tostring(statusCode))
end
else
callback(“http request failed. error(” … tostring(response:getErrorCode()) … ") : " … tostring(response:getErrorMessage()))
end
end

2.2.5增加了进度条的功能，红色部分不能这样做处理。
if event and event.name == “completed” then
if statusCode == 200 then
callback(nil, response:getResponseData())
else
callback(“bad server response. status:” … tostring(statusCode))
end
else
callback(“http request failed. error(” … tostring(response:getErrorCode()) … ") : " … tostring(response:getErrorMessage()))
end

#10

const string CCHTTPRequest::getResponseString(void)
{
CCAssert(m_state == kCCHTTPRequestStateCompleted, “CCHTTPRequest::getResponseString() - request not completed”);
return string(m_responseBuffer ? static_cast<char*>(m_responseBuffer) : “”);
}

void *CCHTTPRequest::getResponseData(void)
{
CCAssert(m_state == kCCHTTPRequestStateCompleted, “CCHTTPRequest::getResponseData() - request not completed”);
void *buff = malloc(m_responseDataLength);
memcpy(buff, m_responseBuffer, m_responseDataLength);
return buff;
}

原来是这的事 我调的getResponseString 但消息里边有个0 string(m_responseBuffer ? static_cast<char*>(m_responseBuffer) : “”);给截断了 改成getResponseData 就好了
