php editor Xinyi is here to introduce to you about SASL loss and Franz-go kafka authentication issues. When using Franz-go kafka for authentication, sometimes you encounter SASL loss, causing authentication failure. This issue can be caused by a variety of reasons, such as configuration errors, network issues, etc. There are many ways to solve this problem, which can be solved by checking the configuration, restarting the service, troubleshooting the network connection, etc. In this article, we will introduce the causes and solutions to this problem in detail, hoping to help everyone.
Question content
I am getting these error messages
<code> "re-updating metadata due to err: broker closed the connection immediately after a request was issued, which happens when SASL is required but not provided: is SASL missing?" "read from broker errored, killing connection after 0 successful responses (is SASL missing?)" </code>
I'm trying to add authentication. My code is:
auth := scram.Auth{ User: "kafka_user", Pass: "kafka_pass", } cl, err := kgo.NewClient( kgo.SeedBrokers(seeds...), kgo.DialTLSConfig(tlsConfig), kgo.SASL(auth.AsSha512Mechanism()), kgo.ConsumerGroup(consumerGroupId), kgo.ConsumeTopics(topics...), kgo.WithLogger(kzap.New(logger.GetLogger())), )
The requirements for authentication are:
- SSL: false
- Security protocol: SASL_PLAINTEXT
- SASL mechanism: SCRAM-SHA-512
- Username:
- Password:
I tried everything in the documentation. Even with the help of google bard and Bing AI and trying all possible solutions, this problem still persists.
Solution
There is no problem with the package. The code is not deployed, so the problem is not with the code but with the deployment.

Developers should follow the following best practices: 1. Carefully manage goroutines to prevent resource leakage; 2. Use channels for synchronization, but avoid overuse; 3. Explicitly handle errors in concurrent programs; 4. Understand GOMAXPROCS to optimize performance. These practices are crucial for efficient and robust software development because they ensure effective management of resources, proper synchronization implementation, proper error handling, and performance optimization, thereby improving software efficiency and maintainability.

We need to customize the error type because the standard error interface provides limited information, and custom types can add more context and structured information. 1) Custom error types can contain error codes, locations, context data, etc., 2) Improve debugging efficiency and user experience, 3) But attention should be paid to its complexity and maintenance costs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
