Ta的回复 ：是C++代码，access_token也是按照官方的文档得到的： int FaceMatch::match(string &json_result, const std::vector<string> &images, const std::string &access_token) { std::string url = face_match_url + "?access_token=" + access_token; CURL *curl = NULL; CURLcode result_code; int is_success; curl = curl_easy_init(); if (curl) { std::string image_plain = images[0]; for (int i = 1; i < images.size(); i++) { image_plain.append("," + images[i]); } curl_easy_setopt(curl, CURLOPT_URL, url.data()); curl_easy_setopt(curl, CURLOPT_POST, 1); curl_httppost *post = NULL; curl_httppost *last = NULL; curl_formadd(&post, &last, CURLFORM_COPYNAME, "images", CURLFORM_COPYCONTENTS, image_plain.data(),CURLFORM_END); //curl_formadd(&post, &last, CURLFORM_COPYNAME, "images", CURLFORM_COPYCONTENTS,"【img_1,img_2】",CURLFORM_END); curl_easy_setopt(curl, CURLOPT_HTTPPOST, post); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, callback); result_code = curl_easy_perform(curl); if (result_code != CURLE_OK) { fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(result_code)); is_success = 1; return is_success; } cout<<"result_code=" <<result_code<<endl; json_result = face_match_result; curl_easy_cleanup(curl); is_success = 0; } else { fprintf(stderr, "curl_easy_init() failed."); is_success = 1; } return is_success; }
