[英]Multiple JSON root elements - Twitter API stream
我以前看過這個問題,但是答案並沒有幫助我,所以我在這里嘗試一下:
我正在使用Twython從Twitter API傳輸實時推文。 這些推文使用以下內容附加到json文件中:
with open('fetched_tweets.json','a') as tf:
y = json.dump(data,tf)
我的問題:
這是來自twitter API的JSON響應的示例:

如您所見,這些推文隨后被轉儲到json文件中,並創建了多個JSON根元素錯誤error ,這使該文件無效。
我需要的:
我需要在API流推文時分離每個對象,因為之后我會將這個文件放在Bigquery中。
我將文件追加邏輯更改為:
with open('fetched_tweets.json','a') as tf:
json.dump(data, tf)
tf.write("\n")
然后,當您讀取文件時:
with open('fetched_tweets.json', 'r') as tf:
for line in tf:
data = json.loads(line)
# save the `data` dictionary to BigQuery
具有上述邏輯將確保每個json對象在單獨的行上,因此用“ \\ n”分隔。
