Ich arbeite an einem Plugin für Obsidian und habe mir den Kopf zerbrochen, um Bilder hochzuladen. Hier ist, was ich bisher habe:
async uploadImages(imageReferences: string[]): Promise<string[]> {
const imageUrls = [];
for (const ref of imageReferences) {
const filePath = this.app.metadataCache.getFirstLinkpathDest(ref, this.activeFile.name)?.path;
if (filePath) {
const file = this.app.vault.getAbstractFileByPath(filePath) as TFile;
if (file) {
try {
const arrayBuffer = await this.app.vault.readBinary(file);
const blob = new Blob([arrayBuffer]);
const boundary = '----WebKitFormBoundary7MA4YWxkTrZu0gW';
let body = '';
body += `--${boundary}\r\n`;
body += `Content-Disposition: form-data; name=\"type\"\r\n\r\n`;
body += "composer\r\n";
body += `--${boundary}\r\n`;
body += `Content-Disposition: form-data; name=\"synchronous\"\r\n\r\n`;
body += "true\r\n";
body += `--${boundary}\r\n`;
body += `Content-Disposition: form-data; name=\"files[]\"; filename=\"${file.name}\"\r\n`;
body += `Content-Type: image/jpg\r\n\r\n`
body += blob + '\r\n';
body += `--${boundary}--\r\n`;
console.log(body)
const formData = new TextEncoder().encode(body)
const url = `${this.settings.baseUrl}/uploads.json`;
const headers = {
"Api-Key": this.settings.apiKey,
"Api-Username": this.settings.disUser,
"Content-Type": `multipart/form-data; boundary=${boundary}`
};
const response = await requestUrl({
url: url,
method: "POST",
body: formData,
throw: false,
headers: headers,
});
//const response = await fetch(url, {
// method: "POST",
// body: formData,
// headers: new Headers(headers),
//});
console.log(`Upload Image response: ${response.status}`);
//if (response.ok) {
if (response.status == 200) {
const jsonResponse = response.json();
console.log(`Upload Image jsonResponse: ${JSON.stringify(jsonResponse)}`);
imageUrls.push(jsonResponse.url);
} else {
new NotifyUser(this.app, `Error uploading image: ${response.status}`).open();
console.error(`Error uploading image: ${JSON.stringify(response.json)}`);
//console.error("Error uploading image:", response.status, await response.text());
}
} catch (error) {
new NotifyUser(this.app, `Exception while uploading image: ${error}`).open();
console.error("Exception while uploading image:", error);
}
} else {
new NotifyUser(this.app, `File not found in vault: ${ref}`).open();
console.error(`File not found in vault: ${ref}`);
}
} else {
new NotifyUser(this.app, `Unable to resolve file path for: ${ref}`).open();
console.error(`Unable to resolve file path for: ${ref}`);
}
}
return imageUrls;
}
Ich erstelle ein multipart/form-data, da requestURL() keinen formData() als Parameter akzeptieren kann. Nur string oder arrayBuffer. Ich kann fetch() nicht verwenden, da ich einen CORS-Fehler erhalte. Mit diesem Code (und vielen kleineren Anpassungen am body) erhalte ich folgenden Fehler:
Error uploading image: {“errors”:[“You supplied invalid parameters to the request: Discourse::InvalidParameters”],“error_type”:“invalid_parameters”}
