Hello everyone, I'm @xiaoqiangapi , a Chinese teacher who has been teaching Chinese for over a decade. Yes, that's the one who, because of one sentence from a student, forced himself to build an API gateway from scratch. In the previous article, I tested the overseas latency speeds of DeepSeek, Zhipu, and MiniMax. But you will surely have questions: "Is your API secure?" "Will the Key leak?" "Will the data be intercepted by a man-in-the-middle?" I wasn't in a hurry to answer. Because I'm not a security expert. I'm just a beginner who has just learned to use Postman, a former Chinese teacher who only started learning API transit at nearly 0 years old. But I decided to use the stupidest method: test one item at a time and write down the results honestly. I used only two tools: Windows' built-in curl No fancy scanner, no professional security platform. I believe plain tests are more persuasive than pretty ads. What am I going to test?…
