为什么在尝试 http 发布时会收到 CURLE_URL_MALFORMAT? [英] Why do I get a CURLE_URL_MALFORMAT when trying to http post?

问题描述

这是代码(从现有应用程序中提取):

Here's the code (extracted from an existing application):

CURL *curl = curl_easy_init();
_ASSERTE(curl);

string url = "http://127.0.0.1:8000/";

char *data = "mode=test";
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
curl_easy_setopt(curl, CURLOPT_URL, url);
CURLcode res = curl_easy_perform(curl);

bool success = (res == CURLE_OK);

curl_easy_cleanup(curl);

res 的值为 CURLE_URL_MALFORMAT.这个网址与 curl 不兼容吗?

The value of res is CURLE_URL_MALFORMAT. Is this URL not compatible with curl?

推荐答案

啊，简单的错误，我需要将 char * 传递给 curl_easy_setopt 而不是 string.为了解决这个问题，我刚刚使用了 .c_str() 像这样:

Ah, simple mistake, I need to pass char * to curl_easy_setopt and not string. To fix this I've just used .c_str() like so:

CURL *curl = curl_easy_init();
_ASSERTE(curl);

string url = "http://127.0.0.1:8000/";

char *data = "mode=test";
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
CURLcode res = curl_easy_perform(curl);

bool success = (res == CURLE_OK);

curl_easy_cleanup(curl);
