When IOS uses APNS to push Payload in bytes, the push fails.

When IOS uses APNS to push Payload in bytes, the push fails.

In the past two days, you need to add a script to the push. You can add a script to the badge method. However, the push fails. I have been depressed for a long time and search for relevant information online.
I finally found the reason:
"Payload -- a maximum of 256 bytes."

It turns out that the payload Bytes Sent exceeds the specified characters.
Use payload. getBytes (). length to get the number of bytes. Check that the number of characters below is 240 bytes, no more than 256. After repeated tests, we know that bytes is not accurate enough. Some values in the original payload are removed (loginUri logon, uri is used for redirect). test again and push is successful.

Is the push (APNs) fee charged for iOS and Android?

Apple's APNs push does not charge traffic. The maximum load for each push notification is 256 bytes. However, there are resident processes in the device background to maintain real-time SSL connections (or pure
When the Wi-Fi environment is in standby mode at the same time), this requires additional traffic, but not much.
Android push compares traffic fees, and each of its applications establishes a persistent connection link.

The Iphone can only be pushed in wifi environments, but not in cmnet. How can I solve this problem if I cannot establish a connection with APNS?

This is why mobile companies have disabled the push function. It cannot be solved. As far as I know, mobile networks in Jinan, Chongqing, and other cities cannot be pushed. The port is blocked. However, a few cities are normal, such as Beijing.
You can install a backgrounder software. Instead of pushing the software, you can run QQ and other software in the background. However, this consumes power.

The solution is to change the China Unicom 3G card. Originally, the iPhone was designed for the WCDMA network.
