HELP: SPIFFS File I/O to firebase #24

Closed usrdes closed 5 years ago

usrdes commented 5 years ago

Hi Mobizt

(Sorry if I repeat this question from closed issue "Save Data to Internal Memory ...." , please delete this new issue if this is repeat and you can help in the other thread)

Is it possible to "setfile" from SPIFF as follows: Firebase.setFile(firebaseData, path, "/myfile.txt", StorageType::SPIFFS) I see your QueueStorageType in your answer above, but it means one has to setup a que. How about just reading from SPIFFS storage and doing file I/O from firebase?

Thank you

I will add this feature in the next library update. The next update, user can also upload/download file (SD and SPIFFS) to cloud storage data bucket.

OK, looking forward to it & also the update to include firestore access :-)

Your data you saved to file contains line breaks which is not valid for JSON.

You can set temporary data in FirebaseJson object and save (serialized) to file when needed using toString(file) and you can read (deserialize) the JSON content from file to FirebaseJson object directly.

This example shows how to read JSON content from file and save JSON content in FirebaseJson object to file.

The example above required the latest version library update.

I have tried the following code but it doesn't work. Sorry for the inconvenience, can you give me a solution. I thank you so much. image I tried saving the object using the following code and it returns json . But the problem I'm having is transferring this data to Firebase. I'm a newbie trying to learn about it can you give me some suggestions. Thank you very much Way 1 image Way 2 image

Did you understand "line breaks" I mentioned?

It means "new line" character or "enter" which should not contains in the string of path or key and value of data

Thank you, I will watch it again

The first method seems to be ok but the second method is not ok as it uses println which append new line to your data.

The first method use printTo of that JSON library which I never try that, you should check if it appended new line, it can't use.

The example I mentioned above is easier to serialize or deserialize JSON to/from File https://github.com/mobizt/Firebase-ESP32/blob/master/examples/FirebaseJson/examples/Stream/File/File.ino

You should learn how to use FirebaseJson library which is the built-in class that manage the JSON data for the Firebase client library.

Other JSON libraries other than FirebaseJson are not supported by this Firebase library.

FirebaseJson is now powered by cJSON the best and light weight and efficient JSON library in C.
