说明
typescript web3 isaddress示例是从最受好评的开源项目中提取的实现代码，你可以参考下面示例的使用方式。
编程语言: TypeScript
命名空间/包名称: web3
示例#1
文件：
assert.ts
项目：
linki/0x.js
const isBigNumber = _.isObject(value) && value.isBigNumber;
this.assert(isBigNumber, this.typeAssertionMessage(variableName, 'BigNumber', value));
},
isUndefined(value: any, variableName?: string): void {
this.assert(_.isUndefined(value), this.typeAssertionMessage(variableName, 'undefined', value));
},
isString(variableName: string, value: string): void {
this.assert(_.isString(value), this.typeAssertionMessage(variableName, 'string', value));
},
isHexString(variableName: string, value: string): void {
this.assert(_.isString(value) && HEX_REGEX.test(value),
this.typeAssertionMessage(variableName, 'HexString', value));
},
isETHAddressHex(variableName: string, value: string): void {
const web3 = new Web3();
this.assert(web3.isAddress(value), this.typeAssertionMessage(variableName, 'ETHAddressHex', value));
this.assert(
web3.isAddress(value) && !web3.isChecksumAddress(value),
`Checksummed addresses are not supported. Convert ${variableName} to lower case before passing`,
);
},
doesBelongToStringEnum(variableName: string, value: string,
stringEnum: any /* There is no base type for every string enum */): void {
const doesBelongToStringEnum = !_.isUndefined(stringEnum[value]);
const enumValues = _.keys(stringEnum);
const enumValuesAsStrings = _.map(enumValues, enumValue => `'${enumValue}'`);
const enumValuesAsString = enumValuesAsStrings.join(', ');
assert.assert(
doesBelongToStringEnum,
`Expected ${variableName} to be one of: ${enumValuesAsString}, encountered: ${value}`,
);示例#2
