我希望你一切都好,所以我已经使用nodejs一段时间了,而且我仍然习惯于异步功能和东西,所以事情是我使用axios从服务器下载图像,然后等待要下载图片,然后使用图片在wordpress网站上发布帖子,该代码有点棘手,因为它可以处理几篇文章,但其他代码只是不等待图片完全下载,而只是分享帖子没有图片。
axios.get(encodeURI(img), {responseType: "stream"} )
.then(response => {
// Saving file to working directory
response.data.pipe(fs.createWriteStream("images/"+title.replace(/[^\x00-\x7F]/g, "")+".png"));
await sleep(3000);
var wp = new WPAPI({
endpoint: 'XXXXX/wp-json',
// This assumes you are using basic auth, as described further below
username: 'XXXX',
password: 'XXXXX'
});
wp.posts().create({
title: title,
content: index,
categories: [3,9,2],
status: 'publish'
}).then(function( post ) {
// Create the media record & upload your image file
var filePath = "images/"+title.replace(/[^\x00-\x7F]/g, "")+".png";
return wp.media().file( filePath ).create({
title: title,
// This property associates our new media record with our new post:
post: post.id
}).then(function( media ) {
console.log( 'Media uploaded with ID #' + media.id );
return wp.posts().id( post.id ).update({
featured_media: media.id
});
});
});
})
.catch(error => {
console.log(error);
});
所以我想问我如何才能完全等到文件夹中的图像存在,然后再分享帖子。
答案 0 :(得分:1)
代替
response.data.pipe(fs.createWriteStream("images/"+title.replace(/[^\x00-\x7F]/g, "")+".png"));
await sleep(3000);
使用
response.data.pipe(fs.createWriteStream("images/"+title.replace(/[^\x00-\x7F]/g, "")+".png"))
.on('error', () => {
// log error and process
})
.on('finish', () => {
// publish a post with image on a wordpress website,
});
P.S。 :尝试编写模块化代码,
