ESP32 连接到 web3 时出现核心异常的 abort()

Question

我用这个库将 esp32 WROOM-32D 连接到 web3。 https://github.com/kopanitsa/web3-arduino

我使用 Arduino Ide 和 Platformio 测试了该库的 eth_send 示例

连接到Wifi后异常是这样的

我用ESP异常解码器解码了错误异常，错误被解码为这样

这是我的代码

#include <WiFi.h>
#include <Web3.h>
#include <Contract.h>

#define USE_SERIAL Serial

const char* ssid = "V1A7C";
const char* password =  /*<password>*/;
#define MY_ADDRESS "0x1b9aE0Be6d87e79b9Bd5A6FcDc67d92F76F6e0F6"

#define INFURA_PATH "/v2/1yNgxbZKvL4JzOIjnNUywYue0ruh_Fjt"

const char PRIVATE_KEY[] = {/*<32 bytes of private key>*/};
                            
Web3 web3((string*)INFURA_HOST, (string*)INFURA_PATH);

void eth_send_example();

void setup() {
    USE_SERIAL.begin(115200);

    for(uint8_t t = 4; t > 0; t--) {
        USE_SERIAL.printf("[SETUP] WAIT %d...\n", t);
        USE_SERIAL.flush();
        delay(1000);
    }

    WiFi.begin(ssid, password);

    // attempt to connect to Wifi network:
    while (WiFi.status() != WL_CONNECTED) {
        Serial.print(".");
        // wait 1 second for re-trying
        delay(1000);
    }

    USE_SERIAL.println("Connected");

    eth_send_example();
}

void loop() {
    // put your main code here, to run repeatedly:
}

void eth_send_example() {
    Contract contract(&web3,(string*) CONTRACT_ADDRESS);
    contract.SetPrivateKey((uint8_t*)PRIVATE_KEY);
    uint32_t nonceVal = (uint32_t)web3.EthGetTransactionCount((string *)MY_ADDRESS);

    uint32_t gasPriceVal = 141006540;
    uint32_t  gasLimitVal = 3000000;
    uint8_t toStr[] = CONTRACT_ADDRESS;
    uint8_t valueStr[] = "0x00";
    uint8_t dataStr[100];
    memset(dataStr, 0, 100);
    string func = "mint(uint256)";
    string p = contract.SetupContractData(&func, 123);
    string result = contract.SendTransaction(nonceVal, gasPriceVal, gasLimitVal, (string*) &toStr,(string*) &valueStr,(string*) &p);

    Serial.println(result);
}

Answer 1

您正在将 C char 指针转换为 std::string 指针，如下所示。

#define MY_ADDRESS "..."
...
uint32_t nonceVal = (uint32_t)web3.EthGetTransactionCount((string *)MY_ADDRESS);

不要那样做。 这太疯狂了。

我很快就查看了web3-arduino的来源。 我确信该库的作者是 C++ 的新手。 不要使用它。
