This error is because: after the finish()function, it was called redict. It will be a mistake.
Solution:
Yes, by if self._finished:judging whether the finish()function has been called.
An idiot mistake, the error prompt: Error: cannot get XMLSec1 pre-processor and compiler flags; do you have the libxmlsec1development package installed?
But I didn’t know that it libxmlsec1was a system library, it should be installed with brew, and I also installed it with pip. . . . .
Solution
brew install libxmlsec1

The cause of the problem is that a certain line of code in the icu library cannot find a file and cannot get ICU_VERSIONthe value.
# Install icu
brew install icu4c
# check newest version
ls /usr/local/Cellar/icu4c/
# Edit pyicu installer to work
git clone https://github.com/ovalhub/pyicu.git
# edit setup.py not to query for the version, i.e. change
# ICU_VERSION = subprocess.check_output(('icu-config', '--version')).strip()
# to whatever your version is, e.g.
# ICU_VERSION = '57'
# Install pyicu

Using websocket under the gin framework, this error will be reported if it is a cross-domain request
request origin not allowed by Upgrader.CheckOrigin
The websocket library used is “github.com/gorilla/websocket”
Need to add the following code:
upgrader = websocket.Upgrader{ ReadBufferSize: 1024 , WriteBufferSize: 1024 , // Resolve cross-domain problems CheckOrigin: func(r *http.Request) bool { return true }, }
The code in the official document is a bit problematic. You can call the plus code with the following delay and wait for plus to load.
In addition, add the conditional compilation, only the code below the app will compile
// #ifdef APP-PLUS // trigger when the page loads setTimeout(function(){ if (plus){ var pinf = plus.push.getClientInfo(); var cid = pinf.clientid; // Client ID console.log (cid); // Monitor system notification bar message click event plus.push.addEventListener( ' click ' , function(msg){ // Business logic code for processing click messages }, false); // Monitor and receive transparent message events plus.push.addEventListener( ' receive ' , function(msg){ // Business logic code for processing transparent messages var options = {cover: false }; plus.push.createMessage(msg, " RemoteMSG " ,options); }, false ); } }, 4000 ); // #endif
client_id can be obtained
When using the base64 decode of the standard library, there will be an error of illegal characters. The following function is my test and it can be decrypted normally.
Pay attention to this parameter: base64.RawStdEncoding is the key to solving illegal characters
func Base64Decode(str string ) string { reader: = strings.NewReader(str) decoder: = base64.NewDecoder(base64.RawStdEncoding, reader) // Decoding buf in streaming mode := make([] byte , 1024 ) // Save the decoded data dst := "" for { n, err : = decoder.Read(buf) dst += string (buf[:n]) if n == 0 || err != nil { break } } return dst }
