The ja.getQrCode analysis
The core logic of this function revolves around "parameter processing and task distribution related to QR code generation", in which the key functions and core functions are analyzed as follows:
isAccountRunning() - the pre-checking kernel
Function: Determining whether the current account is in a running state is the "switch" for the execution of the entire function.
Key reason: If the account is not running (returning false), the function will return directly, and all subsequent logic (parameter parsing, broadcast sending, queue processing, etc.) will not be executed. It is the basis for ensuring that the function only runs in a legitimate state.
com.alibaba.fastjson.a.parseObject(str3) - Data parsing core
Function: Parse the parameter str3 (JSON format string) into a JSONObject object and extract all business parameters (such as bankName, useVpn, walletName, etc.).
Key reason: All subsequent business logic (such as determining whether the bank name is valid, obtaining VPN status, wallet information, etc.) depends on the results of this analysis. If the parsing fails (such as str3 formatting is wrong), it will go directly to the catch block and interrupt the process.
AppApplication.getContext().sendBroadcast(intent) - The real-time task distribution core
Function: When runDcepAutoJs is true, send the parsed parameters (bank name, amount, wallet information, etc.) to the specified component (action is com.qpay.dcep.qrcode.rec) via broadcast.
Key reason: This is the "real-time processing branch" of the function, which directly triggers the response of external components to the QR code generation and is one of the direct executors of the core business logic.
this.p.push(map) - Queue task management core
Function: When the real-time processing conditions are not met (runDcepAutoJs is false and this.o is true), encapsulate the parameters as a HashMap and join the queue this.p.
Key reason: This is the "queue processing branch" of the function, which is responsible for staging tasks and waiting for subsequent processing (checkQueueOrder() to check the queue order), which is the core operation of asynchronous task scheduling.
checkQueueOrder() - Queue scheduling core
Function: Invoked after a task is added to the queue, speculated to check the order, priority, or trigger subsequent processing of tasks in the queue (such as executing tasks in the queue).
Key reason: It serves as a bridging point for queue tasks from "staging" to "executing," ensuring that the QR code generation tasks in the queue are handled as expected.
Summary: The most critical function
com.alibaba.fastjson.a.parseObject(str3) is the "data source" of the entire function, from which all business parameters come from.
AppApplication.getContext().sendBroadcast(intent) and this.p.push(map) are the core executors of branch logic, corresponding to two core business scenarios: real-time processing and queue processing, respectively.
Together, these three functions determine the function's core function: parsing parameters and distributing QR code generation tasks based on conditions.
