我正在使用googlecloud的endpoints API并发送double,这是在Android中由float转换的。大多数情况下,这种方法都很有效,但我注意到,对于少量设备,我会遇到以下错误:
400错误请求
{
"code": 400,
"errors": [{
"domain": "global",
"location": "longitude",
"locationType": "parameter",
"message": "Invalid double value: '116.31765747070313'.",
"reason": "invalidParameter"
}],
"message": "Invalid double value: '116.31765747070313'."
}
以下是android端的代码:
void callEndpoints(final int level, final float latitude, final float longitude) {
try {
API.GetPlacesFromLocationV2 remoteData = cbAPI.getPlacesFromLocationV2();
remoteData.setLatitude((double)latitude);
remoteData.setLongitude((double)longitude);
remoteData.setLevel((long) level);
Result res = remoteData.execute();
//Do stuff with res
} catch (IOException e) {
//print error
}
}
下面是python服务器端代码。你知道吗
PLACES_LOCATION_SEARCH_V2_CONTAINER = endpoints.ResourceContainer(
message_types.VoidMessage,
level=messages.IntegerField(1),
longitude=messages.FloatField(2),
latitude=messages.FloatField(3)
)
def getCellIdx(level, lon, lat):
scale = pow(2, level)
cellWidth = FULL_WIDTH / scale
cellHeight = FULL_HEIGHT / scale
wIdx = int((lon + 180.0) / cellWidth)
hIdx = int((lat + 90.0) / cellHeight)
return level * 100000000 + hIdx * 10000 + wIdx
@endpoints.method(PLACES_LOCATION_SEARCH_V2_CONTAINER,
DataCollection,
path="getPlacesFromLocation_v2", http_method='GET',
name="getPlacesFromLocation_v2")
def getPlacesFromLocation_v2(self, request):
cellIdx = placesGridSearch.getCellIdx(request.level,request.longitude,request.latitude)
#Do stuff with cellIdx, includes datastore access and memcache usage
return DataCollection(cellIdx)
谢谢你的帮助。你知道吗
编辑: 一些附加信息,如果我使用相同的云经度值通过API浏览器运行它,我会得到相同的错误,但如果我在本地开发服务器上运行它,则不会得到相同的错误。 看起来endpoints函数从未被调用(没有日志),但是有一个/\u ah/spi/BackendService.logMessages文件描述完全相同错误的日志。你知道吗
Upgrade to Endpoints Frameworks v2。它不会有这个问题。你知道吗
