user agent over 255 characters

Question

user agent over 255 characters

chembo 16

I am developing a program by leveraging the text-to-speech cognitive services on the framework of wechat that we call Miniprogram.

here is my problem: my http request to the cognitive-services can't define my own user-agent, the framework(Miniprogram) will define it automatically, this is how my user-agent looks like:

User-Agent: Mozilla/5.0 (Linux; Android 12; 2206122SC Build/SKQ1.220303.001; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/86.0.4240.99 XWEB/4343 MMWEBSDK/20221011 Mobile Safari/537.36 MMWEBID/5638 MicroMessenger/8.0.30.2260(0x28001E3B) WeChat/arm64 Weixin NetType/WIFI Language/en ABI/arm64 MiniProgramEnv/android

And i got 400 because it's value over 255 characters.
The pain is I can't get around this user-agent problem.

Any suggestion?

I have also encountered the same problem. The Android version of China's largest app, WeChat, and many Android browsers have User-Agent header lengths that exceed 255. Please consider increasing the User-Agent length limit for the text-to-speech service to 512.

By the way, none of the other Speech Services have the User-Agent length limit issue, only this text-to-speech service has the length restriction problem. Please verify if this is reasonable.

@chembo The user agent header accepts a value which is 255 characters are documented in the mentioned link. I do not see a work around for the same if you are using the REST API. Is it possible to use any of the SDKs with this program?

I have tried to install this SDK, but it has been failing and blocked, as shown in the figure below.

However, even if the installation is successful, if the bottom layer still uses the https protocol, the framework will still intercept and rewrite the user-agent.

I also tried with different rest frameworks, but the result is still the same.
