Python爬取2023新PGA Tour赛事特定数据失败求助

核心错误点 #

• GraphQL查询语法完全错误：你的query字段调用格式不符合规范，直接堆砌变量而非通过参数传递，且缺失大量闭合语法符号
• 变量类型不匹配：includeWithdrawn和changesOnly定义为Boolean类型，但你传入了数字0和字符串"false"，需改用布尔值false
• 查询片段缺失：代码中使用了...FieldPlayer片段，但未定义该片段的具体字段，服务器无法解析

修正后的完整代码 #

调试建议 #

• 发送请求后优先打印完整响应内容，查看是否存在errors字段，里面会包含服务器返回的具体错误提示
• 从开发者工具复制GraphQL查询时，务必复制完整内容，包括所有片段定义和参数格式
• 严格匹配变量类型：Boolean类型只能传入true或false，禁止使用字符串或数字替代
