curl错误-ssh层中的79错误

Question

我在c ++代码中使用curl库。我想使用sftp和用户身份验证将文件上传到服务器。虽然我设法从Windows命令行使用

curl -k -T f:/temp/openvpn-config.zip -u user:password sftp://fabrika/tmp/

用选项调用curl

struct stat file_info;
FILE *fd = fopen(f:/temp/openvpn-config.zip,"rb");
int res_st = fstat(fileno(fd), &file_info);
fclose(fd);

ffile.open(f:/temp/openvpn-config.zip,ios::in | ios::binary);

curl_easy_setopt(h_curl, CURLOPT_URL, "sftp://fabrika/tmp/");
curl_easy_setopt(h_curl, CURLOPT_UPLOAD, 1L);
curl_easy_setopt(h_curl, CURLOPT_READDATA, (void*)&ffile);
curl_easy_setopt(h_curl, CURLOPT_READFUNCTION, &ReadCallback);
curl_easy_setopt(h_curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)file_info.st_size);
curl_easy_setopt(h_curl, CURLOPT_SSL_VERIFYPEER, 0L);
curl_easy_setopt(h_curl, CURLOPT_USERPWD, "user:password");

给我错误代码79，将其翻译为“ ssh层中的错误”。我检查了fstat结果，传递给curl的文件大小正确。

编辑：忘记从详细模式添加调试信息，这是

Hostname was NOT found in DNS cache

Curl_addHandleToPipeline: length: 1

显然，我缺少命令行curl使用的某些参数，该参数可以解决问题，对于任何建议，我将不胜感激。

Answer 1

答：我通过curl邮件列表得到了答案，所以这里是为了防止有人像我一样被卡住。上传文件时，curl需要完整的目标路径，包括文件名。所以

curl_easy_setopt(h_curl, CURLOPT_URL, "sftp://fabrika/tmp/openvpn-config.zip");

做到了。

Answer 2

您的应用程序似乎无权读取“id_dsa.pub”，因此 SSH 握手未完成。尝试查看 CURLOPT_CAINFO
