Question

我想使用python将以下JSON格式的字符串发布到端点：

{"station-id": "FMAT2", "lon": "-97.37055556", "value": "8.70", "lat": "32.80805556", "data-type": "PCIRR", "time": "210811", "date": "170417"}

但是当我发送数据时，代码本身会将上述字符串的任何一部分添加到以下字符串中，如下所示：

"{""station-id"": ""FMAT2"", ""lon"": ""-97.37055556"", ""value"": ""8.62"", ""lat"": ""32.80805556"", ""data-type"": ""PCIRR"", ""time"": ""210440"", ""date"": ""170417""}"

你能不能让我知道为什么会发生这样的事情以及如何避免它。必须要说的是，我得到了响应400和429.以下是代码：

import os
import requests
from os import listdir
from os.path import isfile, join
from timeit import default_timer
start = default_timer()
files_in_dir = [ f for f in listdir('C:/Users/bxr5813/Desktop/Send data to 
map') if isfile(join('C:/Users/bxr5813/Desktop/Send data to map',f)) ]
matching = [s for s in files_in_dir if "json.csv" in s]
if len(matching)==0:
    print "No new report at this time"
for i in range(0,len(matching)):
    filename=matching[i]
    with open(filename,"r") as f:
            content=f.readlines()
            for j in range(0, len(content)):
                line=content[j]
                url = 'https://fathomless-journey-
39482.herokuapp.com/observations'
                headers = {"Content-Type":"application/json", "Accept": 
"text/plain", "X-Api-Key": 'lmENUdfazMd5STedwFgodgts'}
                r = requests.post(url, data=line, headers=headers)
                print r
                print line
                j+=1
                f.close()
    #os.remove(filename)
duration = (default_timer() - start)
print "Runnung time is "+str(duration)+" Seconds that is "+str(duration/60)+" 
minutes"

您可以将JSON字符串放入.csv文件中，文件名应包含json.csv。

Answer 1

在您的requests.post（...）行中使用data=json.dumps(line)。在服务器端，使用incoming = json.loads(line)

Answer 2

为了解决这个问题，我使用以下代码来替换＆＃34;＆＃34;用＆＃34;。然后，问题解决了。

line = line.replace ('""','"')
line=line.replace('"{','{')
line=line.replace('}"','}')
