我们尝试用linkedin API制作视频帖子，在上传初始化、视频分割、上传、上传最终确定和发布的整个过程中我没有没有错误，我们甚至第一次成功发布，但现在不再了帖子已发布。
以同样的方式，当我尝试发布重复的 linkedin 帖子时，它会拒绝，因为它是重复的帖子。
代码：
上传视频：

在发布和获取视频的请求下方：
帖子：

我也尝试过this，但分割视频时遇到问题。
我在尝试上传视频时遇到同样的问题< 4Mb (unsplitted video)
问题在于视频的分割方式
videoSplitter()const fs = require('fs')
const path = require('path')
const { exec } = require('child_process')
exports.videoSplitter = async (filePath, uploadInstructions) => {
const outputDir = path.join('./uploads/linkedin', path.basename(filePath, path.extname(filePath)))
if (!fs.existsSync(outputDir)) {
fs.mkdirSync(outputDir, { recursive: true })
}
const videoPaths = []
const splitCommand = `split -b 4194303 ${filePath} ${path.join(outputDir, 'part-')}`
try {
await new Promise((resolve, reject) => {
exec(splitCommand, (error, stdout, stderr) => {
if (error) {
console.error(`Error splitting video: ${error}`)
reject(error)
} else {
resolve()
}
})
})
const partFiles = fs.readdirSync(outputDir).filter(file => file.startsWith('part-'))
if (partFiles.length !== uploadInstructions.length) {
return { error: 'Failed to split video: mismatch between number of parts and upload instructions' }
}
partFiles.forEach((file, index) => {
const absolutePath = fs.realpathSync(path.join(outputDir, file))
const uploadUrl = uploadInstructions[index].uploadUrl
videoPaths.push({ outputFilePath: absolutePath, uploadUrl })
})
} catch (e) {
console.error('Error splitting video:', e)
return { error: 'Failed to split video', details: e }
}
return videoPaths
}
