我在c ++应用程序中创建了一个带有标题的cURL帖子:
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &bufferdata);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, writerResponse);
struct curl_slist *headers=NULL;
char outputmessage[]="";
headers = curl_slist_append(headers, "Accept: application/json");
headers = curl_slist_append(headers, "Content-Type: application/json");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers );
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, cJSONstring.c_str());
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, cJSONstring.length());
curl_easy_setopt(curl, CURLOPT_VERBOSE,1);
curl_easy_setopt(curl, CURLOPT_HEADER,1);
curl_easy_setopt(curl, CURLOPT_DEBUGFUNCTION, my_trace);
curl_multi_add_handle(m_telemetryCurlm, curl);
我创建了一个调用multi perform的线程:
void ContentManager::processTelemetry()
{
m_telemetryThreadRunning = true;
while(m_telemetryThreadRunning)
{
static_cast<ADCAnalytics*>(m_adcAnalytics)->performTelemerty();
usleep(5000);
}
}
void ADCAnalytics::performTelemerty()
{
// number of active downloads
int counter = 0;
// preform downloading
curl_multi_perform(m_telemetryCurlm, &counter);
// handle CURL actions (connection errors, download finish, etc.)
checkCURLMessages();
}
但是当我检查卷曲消息时,我得到了:
12-10 13:23:00.845:I / ADC(17248):buffer = HTTP / 1.1 400 Bad Request
12-10 13:23:00.845:I / ADC(17248):X-TraceUrl:/ appstats / details?time = 1355145806563&amp; type = json

似乎在curl_multi_add_handle和curl_multi_perform之间更改了内容类型。有人知道这里有什么问题吗?我该怎么做才能避免更改内容类型?
添加以下代码时
do {
while(curl_multi_perform(m_telemetryCurlm, &still_running) ==CURLM_CALL_MULTI_PERFORM);
} while (still_running);
设置cURL对象后立即。请求被发送到服务器,我得到了
12-10 13:11:48.105:I / ADC(16845):buffer = HTTP / 1.1 200 OK

所以,我不相信服务器端有问题。

答案 0 :(得分:0)
您不是要将发送的内容类型与收到的内容类型进行比较吗?
