我编写了一个使用libcurl的多线程程序,但有时curl会抱怨它在exec curl_easy_perform之后无法解析主机名,有时候不会.
size_t Http::WriteMemoryCallback(void *contents, size_t size, size_t nmemb, void *userp)
{
size_t realsize = size * nmemb;
MemoryStruct *mem = (MemoryStruct *)userp;
mem->memory = (char *)realloc(mem->memory, mem->size + realsize + 1);
assert(NULL != mem->memory);
memcpy(&(mem->memory[mem->size]), contents, realsize);
mem->size += realsize;
mem->memory[mem->size] = 0;
return realsize;
}
void Http::run(const URL &url, Http::FinishedCallback cbk)
{
CURL *handle = curl_easy_init();
if (handle)
{
MemoryStruct *chunk = new MemoryStruct;
chunk->memory = (char *)malloc(1); /* will be grown as needed by the realloc above …
