我有一個腳本，其中我正在向Esri文件geodatabase寫入一個JSON web服務。我收到錯誤值錯誤：無法將字符串轉換為浮點：微波

我以前使用過完全相同的腳本，U40是所有字符串的數據類型。在

我的腳本和結果如下import json

import jsonpickle

import requests

import arcpy

import numpy

fc = "C:\MYLATesting.gdb\MYLA311"

if arcpy.Exists(fc):

arcpy.Delete_management(fc)

f = open('C:\Users\Administrator\Desktop\myla311.json', 'r')

data = jsonpickle.encode( jsonpickle.decode(f.read()) )

url = "myUrl"

headers = {'Content-type': 'text/plain', 'Accept': '/'}

r = requests.post(url, data=data, headers=headers)

sr = arcpy.SpatialReference(4326)

decoded = json.loads(r.text)

SRAddress = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['SRAddress']

latitude = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['Latitude']

longitude = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['Longitude']

CommodityType = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['ListOfLa311ElectronicWaste']['La311ElectronicWaste'][0]['Type']

ItemType = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['ListOfLa311ElectronicWaste']['La311ElectronicWaste'][0]['ElectronicWestType']

ItemCount = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['ListOfLa311ElectronicWaste']['La311ElectronicWaste'][0]['ItemCount']

CommodityType1 = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['ListOfLa311ElectronicWaste']['La311ElectronicWaste'][1]['Type']

ItemType1 = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['ListOfLa311ElectronicWaste']['La311ElectronicWaste'][1]['ElectronicWestType']

ItemCount1 = decoded['Response']['ListOfServiceRequest']['ServiceRequest'][0]['ListOfLa311ElectronicWaste']['La311ElectronicWaste'][1]['ItemCount']

print SRAddress

print latitude

print longitude

print CommodityType

print ItemType

print ItemCount

print CommodityType1

print ItemType1

print ItemCount1

item ={'SRAddress': SRAddress, 'Longitude': longitude, 'Latitude': latitude, 'CommodityType': CommodityType, 'ItemType': ItemType, 'ItemCount': ItemCount}

import numpy as np #NOTE THIS

keys = ['SRAddress','Longitude','Latitude','CommodityType','ItemType', 'ItemCount']

k1,k2,k3, k4, k5, k6 = keys

data_line ={'SRAddress': SRAddress, 'Longitude': longitude, 'Latitude': latitude, 'CommodityType': CommodityType, 'ItemType': ItemType, 'ItemCount': ItemCount}

frmt = '\nStraight dictionary output\n Address: {} Long: {} Lat: {}'

print(frmt.format(item[k1],item[k2],item[k3], item[k4],item[k5], item[k6]))

print '\noption 1: List comprehension with unicode'

a = tuple([unicode(item[key]) for key in keys]) # list comprehension with unicode

print('{}'.format(a))

dt = np.dtype([('SRAddress','U40'),('CommodityType','U40'), ('ItemType','U40'), ('ItemCount','U40'),('longitude','

arr = np.array(a,dtype=dt)

print'\narray unicode\n',arr

print'dtype',arr.dtype

print '\noption 2:List comprehension without unicode'

b = tuple([item[key] for key in keys])

print('{}'.format(b))

dt = np.dtype([('SRAddress','U40'),('CommodityType','U40'), ('ItemType','U40'), ('ItemCount','U40'),('longitude','

arr = np.array(b,dtype=dt)

print'\narray without unicode\n',arr

print'dtype',arr.dtype

arcpy.da.NumPyArrayToFeatureClass(arr, fc, ['longitude', 'latitude'], sr)

結果

^{pr2}$
