The new file

  • Create a folder named 1121 on the desktop, create file. TXT in the folder, enter data in the file, save the file and exit

    pwd/Users/CHY/Desktoppwd /Users/CHY/Desktoppwd/Users/CHY/Desktop mkdir 1121 cd1121/cd 1121/cd1121/ vi file.txt $ cat File. TXT ha ha, why only I am unhappy

  • When entering the file, use I to start typing

  • After entering, press Exc to exit editing, shift+ colon, and enter wq to save the changes

Add the file to the IPFS node

$ipfs add file. TXT added QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T file. TXT file $cat. TXT haha, $ipfs cat QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T haha, analyzing the specific issues specific analysisCopy the code

  • TXT will be added to the current ipfs node. And for the file. TXT file to generate a unique hash ` ` QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T, if you want to see the data of local ipfs node, Can see through ipfs cat QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T.

  • Ipfs cat QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T and command ipfs cat file. TXT content is the same

  • But through the http://ipfs.io/ipfs/QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T data access, can’t access, because this data is stored in our local, only to be released to the public on a cluster of the IPFS can access.

Synchronize the nodes

  • Run the ipfs daemon command

    $ ipfs daemon Initializing daemon… Adjusting current ulimit to 2048… Successfully raised the file descriptor limit to 2048. The Swarm listening on/ip4 111.196.246.151 / TCP / 3637 Swarm listening on / ip4 127.0.0.1 / TCP / 4001 Swarm listening on/ip4 169.254.170.167 / TCP / 4001 Swarm listening on/ip4/192.168.0.107 / TCP / 4001 Swarm listening on /ip6/::1/ TCP /4001 API Server listening on /ip4/127.0.0.1/ TCP /5001 Gateway (readonly) Server listening On /ip4/127.0.0.1/ TCP /8080 Daemon is ready

Create a directory to store files

  • Using the command ipfs cat QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T liyc1215 view added to the ipfs network file. The content of the TXT file

  • You can also use the ipfs command to create a folder under the ipfs root directory and move or copy the file. TXT file to the folder we created.

  • Cp does not change the file hash, mv changes the hash address

  • Ipfs files mkdir /1122 The new 1122 folder must contain a slash (/)

    ipfsfilesmkdir/1122ipfs files mkdir /1122ipfsfilesmkdir/1122 ipfs files cp /ipfs/QmbrevseVQKf1vsYMsxCscRf6D7S2dftYpHwxkYf94pc7T /1122/file.txt ipfsfilesls/1122ipfs files ls / 1122ipfsfilesls/1122 Ipfs files ls /1122/file. TXT $ipfs files read /1122/file. TXT

Add a directory

An entire directory can be uploaded using ipfs add-r

$ ipfs add -r ipfs-tutorial/

Copy the code

  • QmSsjQDVw1fvmG5RsZMgp2GjihiXn2zDv64mfHZN3AREek hash of a whole

  • TXT files can be viewed by using ipFS CAT hash, while files of other formats must be downloaded and converted. For example, the access code for the above eth-fabric.png file is

    ipfs get /ipfs/QmfKdWsguobA3aDPvSxLB3Bq4HMKyqKSgFr2NFUuVH8n31 -o eth-fabric.png

  • The hash before the file name is their own hash value

Access the contactme. TXT file data by path

  • If we are uploading a directory, there are several ways to access the data in the contactMe. TXT file.

    $ ipfs cat QmYx4BnhnLXeMWF5mKu16fJgUBiVP7ECXh7qcsUZnXiRxc

    $ ipfs cat /ipfs/QmYx4BnhnLXeMWF5mKu16fJgUBiVP7ECXh7qcsUZnXiRxc
