大家好,

FilterQuery fq = new FilterQuery();

double longitude2 = longitude + 8;

此代码用于收集英国和英国的推文。爱尔兰的位置,但不收集推文或有时(很少)从边界框外的区域收集推文。
如果我扩大了边界框,我会收到推文,但有时它们会在边界框之外。
我的工作原理是边界框的第一个点是SW角,下一个点是NE角。
任何想法可能是什么问题?我正在使用Twitter4j 3.0.3
谢谢,
大卫
答案 0 :(得分:3)
我认为你是以错误的顺序发送坐标。根据{{3}},Twitter预计以逗号分隔的经度,纬度列表,但您要发送(纬度,经度)对。
正确的版本应为:
double lat = 53.186288;
double longitude = -8.043709;
double lat1 = lat - 4;
double longitude1 = longitude - 8;
double lat2 = lat + 4;
double longitude2 = longitude + 8;
double[][] bb = {{longitude1, lat1}, {longitude2, lat2}};
FilterQuery fq = new FilterQuery();
fq.locations(bb);
twitterStream.filter(fq);
