curl error - 79 Error in the ssh layer

本文关键字:in the ssh layer Error error 语言 curl      更新时间:2023-10-16

我在c++代码中使用curl库。我想上传一个文件到服务器使用sftp和用户认证。虽然我设法从windows命令行使用

做到这一点
curl -k -T f:/temp/openvpn-config.zip -u user:password sftp://fabrika/tmp/

使用options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");

给了我错误代码79,它翻译成"ssh层错误"。我检查了fstat的结果,传递给curl的文件大小是正确的。

编辑:忘记从详细模式添加调试信息,这里是
Hostname was NOT found in DNS cache

Adding handle: send: 0
Adding handle: recv: 0
Curl_addHandleToPipeline: length: 1

很明显,我遗漏了一些命令行curl使用的参数,如果有任何建议,我将不胜感激。

答案:我通过curl邮件列表得到了答案,所以这里是以防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filename。所以

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

似乎您的应用程序无法读取"id_dsa "。因此SSH握手不会完成。尝试查看CURLOPT_CAINFO
