示例1: sendAsync
public sendAsync(payload: any, callback: any) {
if (!ThorAPIMapping[payload.method]) {
return callback(new Error("Method not supported!"), {
id: payload.id || 0,
jsonrpc: payload.jsonrpc || "2.0",
result: null,
});
}
let ret = ThorAPIMapping[payload.method].ret;
// non-objects does't need isThorified property since thorify just overwritten 3 formatters
// which all accept object as input
if (web3Utils._.isObject(ret)) {
// tricks for fast deep copy since I defined ThorAPIMapping
ret = JSON.parse(JSON.stringify(ret));
Object.defineProperty(ret, "reqBody", { get: () => payload, set: () => null });
Object.defineProperty(ret, "isThorified", { get: () => true, set: () => null });
}

}
callback(null, {
id: payload.id || 0,

}示例2: function
export const mustToBN = function(value: any) {
if (web3Utils._.isNull(value) || web3Utils._.isUndefined(value)) {
throw new Error("input can't be null or undefined");
}
const num = web3Utils.toBN(value);

};示例3: callback

if (request.readyState === 4) {
if (request.status !== 200) {
return callback(new Error("[thorify-provider-http] Invalid response code from provider: " + request.status + (request.responseText ? ", response: " + request.responseText : "")), {

// tricks for compatible with original web3 instance
// non-objects or non-arrays does't need isThorified property since thorify just overwritten 3 formatters
// which all accept object as input
