HCL Domino AppDevPack - 编写富文本的问题
HCL Domino AppDevPack - Problem with writing Rich Text
我用的是the code proposed as an example in the documentation for Domino AppDev Pack 1.0.4,唯一不同的是读取一个文本文件(body.txt)作为缓冲,这个文件只包含简单的长文本(40Ko)。
执行时,文档会在数据库中创建,其余代码不会return出错。
但是最终,富文本字段并没有添加到文档中。
这里的回复 returned:
response: {"fields":[{"fieldName":"Body","unid":"8EA69129BEECA6DEC1258554002F5DCD","error":{"name":"ProtonError","code":65577,"id":"RICH_TEXT_STREAM_CORRUPT"}}]}
我的目标是在富文本字段中编写非常长的文本(超过 64 Ko)。我在示例中使用了一个文本文件作为缓冲区,但稍后可能会像 const buffer = Buffer.from ('very long text ...')
这是正确的方法还是必须采用不同的方法?
我正在使用带有 IBM Domino (r) Server(64 位)版本 10.0.1FP4 和 AppDevPack 1.0.4 的 Windows 系统。

代码如下:
const write = async (database) => {
let writable;
let result;
try {
// Create a document with subject write-example-1 to hold rich text
const unid = await database.createDocument({
document: {
Form: 'RichDiscussion',
Title: 'write-example-1',
},
});
writable = await database.bulkCreateRichTextStream({});
result = await new Promise((resolve, reject) => {
// Set up event handlers.
// Reject the Promise if there is a connection-level error.
writable.on('error', (e) => {
reject(e);
});
// Return the response from writing when resolving the Promise.
writable.on('response', (response) => {
console.log("response: " + JSON.stringify(response));
resolve(response);
});
// Indicates which document and item name to use.
writable.field({ unid, fieldName: 'Body' });
let offset = 0;
// Assume for purposes of this example that we buffer the entire file.
const buffer = fs.readFileSync('/driver/body.txt');
// When writing large amounts of data, it is necessary to
// wait for the client-side to complete the previous write
// before writing more data.
const writeData = () => {
let draining = true;
while (offset < buffer.length && draining) {
const remainingBytes = buffer.length - offset;
let chunkSize = 16 * 1024;
if (remainingBytes < chunkSize) {
chunkSize = remainingBytes;
}
draining = writable.write(buffer.slice(offset, offset + chunkSize));
offset += chunkSize;
}
if (offset < buffer.length) {
// Buffer is not draining. Whenever the drain event is emitted
// call this function again to write more data.
writable.once('drain', writeData);
}
};
writeData();
writable = undefined;
});
} catch (e) {
console.log(`Unexpected exception ${e.message}`);
} finally {
if (writable) {
writable.end();
}
}
return result;
};
从 appdev pack 1.0.4 开始,富文本流接受 LMBCS 字符集中有效的富文本 cd 格式的写入数据。我们目前正在开发一个库来帮助您将有效的富文本数据写入流。
我很想听听更多关于您的用例的信息,我们很高兴您已经开始使用该功能了!如果你能加入 openntf slack 频道,我通常会在那里闲逛。
