Content upload

Before content upload begins, the process includes two necessary steps. You can access the following links to learn the operation process directly through the corresponding guidance.

Necessary operating steps:

• Choose at least two Seeders (How to find the seeder).
• Running the Interstellar File System (IPFS) Server (Setting up IPFS System Server).

To upload content, use the submit_content_async method. In the examples provided, we used the following two seeders: 1.2.17 and 1.2.18.

METHODS:
submit_content_async - This function is used to create, upload content packages and submit content in one step.

void submit_content_async (string author,
                           vector<pair<string, uint32_t>> co_authors,
                           string content_dir,
                           string samples_dir,
                           string protocol,
                           vector<regional_price_info> price_amounts,
                           vector<account_id_type> seeders,
                           fc::time_point_sec expiration,
                           string synopsis);

Parameters:

• author - Content Creator
• co_authors - The name or ID of the co-author account that matches the base-point-based contribution
• content_dir - contains the path of all content directories to be packaged
• amples_dir - The path containing the content sample directory
• protocol - Upload Content Packet protocol (Star File System)
• price_amounts - Content value for each region
• Seeders - a list of seeders who publish content
• Expiration - expiration of content. Content is allowed to be purchased before expiration
• synopsis - Detailed description of content

Examples are given to illustrate:

submit_content_async accountname [] "/path/to/file/testfile.txt" "" "ipfs" \
[{"region":"AE","amount":"1","asset_symbol":"DCT"}] ["1.2.17","1.2.18"] \
"2017-11-17T23:59:59" "{\"content_type_id\":\"0\",\"title\":\"greatTestFile\", \
\"description\":\"some description.. \"}"

Where: According to the list, content_type_id is the number that specifies the target network and content type.

• ContentObject Application Number List
  • 0 - DCore
• ContentObjectType Number List
  0 - None
  1 - Music
  2 - Films
  3 - Books
  4 - Audio Books
  5 - Software
  6 - Games
  7 - Pictures
  8 - Documentation

For example, "0.5" represents the DCore network and the specified Software type.

Result:

submit_content_async accountname [] "/path/to/file/testfile.txt" "" "ipfs" \
[{"region":"AE","amount":"1","asset_symbol":"DCT"}] ["1.2.18","1.2.17"] \
"2017-11-17T23:59:59" "{\"content_type_id\":\"0\",\"title\":\"greatTestFile\", \
\"description\":\"some description.. \"}"
null

Look for the seeder

This is one of the necessary steps in the upload process. The content upload process cannot proceed without specifying the seeder who is ready to upload the content. Select your preferred method from the following text to see who can sow( Through price , region , Upload information , Grade ) Please follow the guidelines provided in this document.

Selection of seeders by price

METHODS:
list_seeders_by_price - Select a list of seeders by price, with the list number from low to high

vector<seeder_object> list_seeders_by_price(uint32_t count);

Parameters:

• count - Maximum number of returned Seeders

Return value:

• Screened list of seeders
