C++ getting an error when uploading file

zangetsu · ‎05-18-2022

Hi,
i'm using an ESP to upload files from an SD card to the dropbox API.
i'm using the following request:

#define upload "/2/files/upload HTTP/1.1\r\n"
#define host_content "Host: content.dropboxapi.com\r\n"
#define content_API "content.dropboxapi.com"

String _mode="overwrite";
SD.begin();
File files = SD.open(localFile,"r+") //local file is test.txt
uint32_t sizeFile=files.size();
client.connect(content_API,443))
client.print(String("POST ") + upload +
               host_content +
               "User-Agent: ESP8266/Arduino_Dropbox_Manager_"+(String)ver+"\r\n" +
               (String)Aut_Bearer + (String)_token +"\r\n" +
               _accept +
               "Dropbox-API-Arg: {\"path\": \"" + address + "\",\"mode\": \"" + _mode + "\",\"autorename\": true,\"mute\": false}\r\n" +
               content_type_octet +
               "Content-Length: " + sizeFile + "\r\n\r\n"
               );

 uint32_t index=0;
  char _buffer[1001];
  while(index<sizeFile){ 
    //yield();
    //ESP.wdtFeed();
    index=index+1000;
    files.readBytes(_buffer,1000);
    _buffer[1000]='\0';
    client.print(_buffer);
  }
  client.flush();
  files.close();   
  //SD.end();
  #ifdef debug_mode
    debug_mode.println("Request sent!");
  #endif
  uint32_t millisTimeoutClient;
  millisTimeoutClient = millis();
  String line;
   while (client.connected() && ((millis()-millisTimeoutClient)<timeout_client) ) { //&& (client.available())

		debug_mode.print(char(client.read()));
}
	client.flush();
	client.stop();
	return true;

even thou the file uploads just fine (i can find the uploadfile in my dropbox) , i'm recieving an error on the http responce:
(the expires in time is current milliseconds of the microcontroller + the time the new token is valid)

Might be a shot in the dark but could it be that the file metadata says it's been created in 1979 (on the SD card) and that that is the reason dropbox.api doesn't like it?

So i'm glad the code "works" (file is getting uploaded , but the 400 code worries me...
I could ignore it , by not reading the responce and stopping the client before the 400 code is being sent, but that doesn't seems like good programming to me....

with kind regards,

Hi @zangetsu,

😁🙂 I have one question: How many HTTP queries are you sending during the HTTP link period?

Slow down, don't get fast. Relax little bit and take a look on the code once again. How many bytes have to be the first query? 😉

I hope you are able figure out already where the second query start from.

Greg-DB · ‎05-19-2022

@zangetsu The file metadata shouldn't cause an issue like this. I do see that you're getting two different HTTP responses though, one with a 200 status code (for the successful file upload), and then one with a 400 status code (which can occur when the servers receive an invalid HTTP request). So, as Здравко indicated, it looks like you may actually be sending more than one HTTP request, perhaps one valid one for the upload call and then one invalid one. (For instance, you might be sending additional data on the connection, after the actual API call data is sent.)
