如何使用‘#number’规则验证Schema？解决类型不匹配问题

问题详情 #

• 根路径$校验失败：名称为'httpCode'的字段匹配失败(MAP:MAP)
• 路径$.httpCode校验失败：数据类型不匹配(STRING:NUMBER)
• 预期校验规则：#number
• 实际响应值：206

Schema定义 #

def SchemaAccountProducts = 
"""
{
"httpCode": "#number",
"httpMessage": "#string",
"timestamp": "#string",
"moreInformation": "#string",
"userFriendlyError": "#string",
"response": {
"cardList": "#(SchemaCardList)",
"accountList": "#(SchemaAccountList)",
"creditList": "#(SchemaCreditList)"
}
}
"""

响应内容 #

{"httpCode":206,"httpMessage":"PARTIAL_CONTENT"}

解决方案 #

问题出在Schema中httpCode的规则写法错误：你把#number用双引号包裹了，这会让校验器将其识别为字符串类型校验规则，但实际响应里的httpCode是数字类型的206，因此触发了类型不匹配的错误。

修正方法很简单：去掉#number周围的双引号，让规则直接指定字段的数字类型校验要求。修正后的httpCode字段定义如下：

"httpCode": #number

完整修正后的Schema：

def SchemaAccountProducts = 
"""
{
"httpCode": #number,
"httpMessage": "#string",
"timestamp": "#string",
"moreInformation": "#string",
"userFriendlyError": "#string",
"response": {
"cardList": "#(SchemaCardList)",
"accountList": "#(SchemaAccountList)",
"creditList": "#(SchemaCreditList)"
}
}
"""

这样校验器就能正确识别httpCode字段需要是数字类型，与响应中的206匹配，通过校验。
