我希望编写一个C ++程序,将返回的标头保存到变量中,并将返回的主体保存到文本文件中。我怎么能这样做?
目前,我的方法是重载handleData
函数,但编译器返回错误overloaded function with no contextual type information
。这是我到目前为止所写的内容(代码摘录):
static size_t handleData(char *ptr, size_t size, size_t nmemb, string *str){
string temp = string(ptr);
// catch the cookie
if (temp.substr(0,10)=="Set-Cookie"){
*str = temp;
}
return size * nmemb;
}
static size_t handleData(char *ptr, size_t size, size_t nmemb, FILE *stream){
int written = fwrite(ptr, size, nmemb, stream);
return written;
}
FILE *bodyfile;
string *return_header = new string;
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, handleData);
curl_easy_setopt(curl, CURLOPT_HEADERDATA, return_header);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, bodyfile);
答案 0 :(得分:2)
您应该使用CURLOPT_HEADERFUNCTION代替。
static size_t handleHeader(char *ptr, size_t size, size_t nmemb, string *str){
// ...
}
static size_t handleData(char *ptr, size_t size, size_t nmemb, FILE *stream){
// ...
}
curl_easy_setopt(curl, CURLOPT_HEADERFUNCTION, handleHeader);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, handleData);
curl_easy_setopt(curl, CURLOPT_HEADERDATA, return_header);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, bodyfile);
