Maybe I’m missing something but what exactly do you expect the Content-Description string to contain if not NULL? Also I don’t see where your code prints the “content encoding” so I have no idea how you are getting that value, but will point out the following method signature: GMimeContentEncoding g_mime_part_get_content_encoding (GMimePart *mime_part); GMimeContentENcoding is an enum, not a string, and the default value (i.e. when no encoding is specified) is `0`, so if you try to print `0` as a string, it’s NULL. Hope that helps, Jeff From: gmime-devel-list <gmime-devel-list-bounces gnome org> on behalf of Yuval Peduel via gmime-devel-list <gmime-devel-list gnome org> My apologies if this has been covered but I couldn't find a way of doing an effective search in the archives. I'm new to GMIME so I wrote a small test program to parse and print out the MIME structure of emails. When I get to a part, I try to get the content description and the content encoding. The char* returned by the corresponding functions
is always NULL. I'm running the code on Mac OSX Sierra The relevant portion of the raw message is: Subject: test message To: yuval peduel <ypeduel yahoo-inc com> Content-Type: multipart/alternative; boundary="94eb2c043cb48bca710554265079" Content-Length: 328 --94eb2c043cb48bca710554265079 Content-Type: text/plain; charset="UTF-8" I'm expecting this message to have two MIME sections --94eb2c043cb48bca710554265079 Content-Type: text/html; charset="UTF-8" <div dir="ltr">I'm expecting this message to have two MIME sections<div><br></div></div> --94eb2c043cb48bca710554265079-- The code fragments that I think are relevant are: GMimeMessage* message = g_mime_parser_construct_message(parser, NULL); /* unref the parser since we no longer need it */ g_object_unref (parser); error = process_gmime_message(message, params); int process_gmime_message(GMimeMessage* message, po::variables_map ¶ms) { int error = 0; GMimeObject * mime_part = g_mime_message_get_mime_part(message); cout << "In process_gmime_message, the top level part is "; if (GMIME_IS_MESSAGE_PART(mime_part)) { cout << " recognized as MESSAGE_PART\n"; } else if (GMIME_IS_MULTIPART(mime_part)) { cout << " recognized as MULTI_PART "; GMimeMultipart* multipart = (GMimeMultipart *)mime_part; int part_count = g_mime_multipart_get_count(multipart); cout << "with " << part_count << " contained parts\n"; process_mime_multipart(multipart, 0); } else if (GMIME_IS_PART(mime_part)) { cout << " recognized as PART\n"; process_mime_part((GMimePart *)mime_part, 0); } else cout << " not recognized as part\n"; return error; } void process_mime_multipart(GMimeMultipart* multipart, int level) { cout << "process_mime_multipart called" << endl; if (multipart == NULL) { cout << "ERROR: NULL part" << endl; return; } string indent = " "; for (int depth = 0; depth < level; ++depth) indent += " "; cout << indent << "mime multi-part:" << endl; int count = g_mime_multipart_get_count(multipart); for (int ndx = 0; ndx < count; ++ndx) { GMimeObject* mime_part = g_mime_multipart_get_part(multipart, ndx); if (GMIME_IS_MESSAGE_PART(mime_part)) { cout << " recognized as MESSAGE_PART\n"; } else if (GMIME_IS_MULTIPART(mime_part)) { cout << " recognized as MULTI_PART "; GMimeMultipart* multipart = (GMimeMultipart *)mime_part; int part_count = g_mime_multipart_get_count(multipart); cout << "with " << part_count << " contained parts\n"; process_mime_multipart(multipart, level+1); } else if (GMIME_IS_PART(mime_part)) { cout << " recognized as PART\n"; process_mime_part((GMimePart *)mime_part, level+1); } else cout << " not recognized as part\n"; } } void process_mime_part(GMimePart *part, int level) { cout << "process_mime_part called" << endl; if (part == NULL) { cout << "ERROR: NULL part" << endl; return; } string indent = " "; for (int depth = 0; depth < level; ++depth) indent += " "; cout << indent << "mime part:" << endl; const char* description = g_mime_part_get_content_description(part); cout << indent << "- content description: "; if (description) cout << description; else cout << "NULL"; cout << endl; My output looks like: In process_gmime_message, the top level part is recognized as MULTI_PART with 2 contained parts process_mime_multipart called mime multi-part: recognized as PART process_mime_part called mime part: - content description: NULL - content encoding: NULL recognized as PART process_mime_part called mime part: - content description: NULL - content encoding: NULL which seems to be saying that I'm recognizing the two MIME parts, just not getting the relevant data. Suggestions? Questions whose answers will help you help me? TIA. |
