我自己的 ReactJs 代码：

        try{
            await this.DMR.methods.getPatientDetails(this.state.account).call().then((res)=>{
                let result = res;
                console.log(result);
            });
        }
        catch(e){
            await this.setState({load:false});
            console.log(e);
        }

功能测试说明：

首先您需要使用 addPatient 函数创建患者，您可以使用上面的 oneclickapp 链接创建患者。 然后使用getPatientDetails函数获取患者信息（应该是您自己创建患者的地址），您可以在oneclick app中查看您的详细信息。

使用 oneclickapp 可以正常工作，但是我自己的 web3 源代码：

给我错误：

错误：溢出（fault="overflow", operation="toNumber", value="3963877391197344453575983046348115674221700746820753546331534351508065746944", code=NUMERIC_FAULT, version=bignumber/5.0.7）

我不明白为什么函数返回所有字符串时会发生溢出。

注意：DMR 是我的合约实例，它工作正常，因为我能够正确获取其他功能。

Answer 1

您不应该将 Promise 构造混合在一起（async/await 与 .then），至于直接问题，您介意转储完整的堆栈跟踪吗？

        try{
            const res = await this.DMR.methods.getPatientDetails(this.state.account).call();
            console.log(res);
        }
        catch(e){
            await this.setState({load:false});
            console.log(e);
        }
