示例1: signOrderHashAsync

    public async signOrderHashAsync(orderHash: string): Promise<ECSignature> {
        utils.assert(!_.isUndefined(this._zeroEx), 'ZeroEx must be instantiated.');
        const makerAddress = this._userAddressIfExists;
        // If makerAddress is undefined, this means they have a web3 instance injected into their browser
        // but no account addresses associated with it.
        if (_.isUndefined(makerAddress)) {
            throw new Error('Tried to send a sign request but user has no associated addresses');
        }

        this._showFlashMessageIfLedger();
        const nodeVersion = await this._web3Wrapper.getNodeVersionAsync();
        const isParityNode = utils.isParityNode(nodeVersion);
        const isTestRpc = utils.isTestRpc(nodeVersion);
        const isLedgerSigner = !_.isUndefined(this._ledgerSubprovider);
        let shouldAddPersonalMessagePrefix = true;
        if ((isParityNode && !isLedgerSigner) || isTestRpc || isLedgerSigner) {

        const ecSignature = await this._zeroEx.signOrderHashAsync(
            orderHash,
            makerAddress,
            shouldAddPersonalMessagePrefix,
