thrift 接受一个对象列表的问题

[ray1888]

刚刚公司在用 thrift 来搞一个项目，然后正在尝试接受一个列表，里面包含定义好的结构体， 那么为什么我直接用遍历列表不能取得结构体里面的元素

c 端语言是 java，s 端语言是 python

我在二楼放上 thrift 文件，3 楼放上代码，有大神能帮忙看一下吗？搜索了很多资料还是没有一个准确的解决方法

### thriftfile
struct Span {
1: i64 trace_id # unique trace id, use for all spans in trace
2: string name,
3: i64 id, # unique span id, only used for this span
4: optional i64 parent_id, # parent span id
5: list<Annotation> annotations, # all annotations/events that occured, sorted by timestamp
6: list<BinaryAnnotation> binary_annotations # any binary annotations
7: optional bool debug = 0 # if true, we DEMAND that this span passes all samplers
8: optional i64 timestamp,
9: optional i64 duration
10: optional i64 trace_id_high
}

service Agent {
oneway void emitZipkinBatch(1: list<Span> spans)
}

我只尝试过用饿了么 thriftpy 官方文档中的 rpc 做过 demo，总体没啥问题，你这 thrift 是什么包

[ray1888]

@zgbgx1 他原来是一个 uber 的一个分布式追踪的项目，我想服用它的 c 端，自己写 server 端

@ray1888 client 不是 java 吗，你这 server 端 python 建议直接用 https://github.com/eleme/thriftpy
