오류 처리에 접근 API

Question

나는 아래 for 루프 내에서 여러 초록을 다운로드, 파이썬을 통해 API (스코 푸스)에 액세스하려고 : 그렇게에,

for t in eid: 
    url = "http://api.elsevier.com/content/abstract/eid/"+str(t)+"?view=FULL" 
    # url = "http://api.elsevier.com/content/abstract/eid/2-s2.0-84934272190?view=FULL" 
    resp2 = requests.get(url, 
         headers={'Accept':'application/json', 
         'X-ELS-APIKey': MYAPIKEY}) 

    retrieval = resp2.json() 

    dep = retrieval['abstracts-retrieval-response']['item']['bibrecord']['head']['author-group'] 
    sub = retrieval['abstracts-retrieval-response']['subject-areas']['subject-area'] 
    iD = retrieval['abstracts-retrieval-response']['coredata']['intid'] 
    date = retrieval['abstracts-retrieval-response']['coredata']['prism:coverDate'] 

    department.append(dep) 
    subj.append(sub) 
    ident.append(iD) 
    dates.append(date) 

그러나 나는 따라 다음과 같은 오류를 수신 유지 아래의 행 (항상 for 루프의 다른 지점에도 있음). 오류 처리가이 문제를 해결하는 방법이라고 들었지만, 파이썬에 익숙하지 않은 것은 무엇인지 모르겠습니다. 누구든지 도와 줄 수 있습니까? 감사합니다

Answer 1

(이 긴 점에 대해 유감으로) 올바른 정보를 모두 포함해야 전체 오류 메시지입니다 귀하의 산출물.

일반적으로 코드 조각 실행 중에 예외 상황 (예 : 오류)이 발생하면 해당 예외를 catch하여 처리 할 수 ​​있습니다. 예외는 무엇이 잘못되었는지에 관한 정보가있는 객체입니다. 예외 처리는 일반적으로 큰 문제이므로 다음 위치에서 읽기 시작할 수 있습니다. https://docs.python.org/3/tutorial/errors.html

예외 처리의 예로는 상황과 예외를보고하는 것입니다. 이것은 이미 무엇이 잘못되었는지에 당신에게 통찰력을 줄 수 :

for t in eid: 
    try: 
     url = "http://api.elsevier.com/content/abstract/eid/"+str(t)+"?view=FULL" 
     # url = "http://api.elsevier.com/content/abstract/eid/2-s2.0-84934272190?view=FULL" 
     resp2 = requests.get(url, 
          headers={'Accept':'application/json', 
          'X-ELS-APIKey': MYAPIKEY}) 

     retrieval = resp2.json() 

     dep = retrieval['abstracts-retrieval-response']['item']['bibrecord']['head']['author-group'] 
     sub = retrieval['abstracts-retrieval-response']['subject-areas']['subject-area'] 
     iD = retrieval['abstracts-retrieval-response']['coredata']['intid'] 
     date = retrieval['abstracts-retrieval-response']['coredata']['prism:coverDate'] 

     department.append(dep) 
     subj.append(sub) 
     ident.append(iD) 
     dates.append(date) 
    except Exception as exception: 
     print (url) # 'print' will only work on a console 
     print (exception) 

[편집]

나는 오류 메시지에서 살펴 보았다 그것은 보인다 당신이에 연결을 시도하고있는 서버, 연결을 종료했습니다. 원인은 완전히 다를 수 있지만 Why is host aborting connection?을 참조하십시오. 사용이 모든 시간을 발생 또는 유일한

일부 시도에서 빌드로 특정 URL의

[/ 편집]에 있는지 확인하려면 위의 코드를 사용해보십시오 :

import time 

nrOfTries = 10 

for t in eid: 
    for count in range (nrOfTries): 
     try: 
      url = "http://api.elsevier.com/content/abstract/eid/"+str(t)+"?view=FULL" 
      # url = "http://api.elsevier.com/content/abstract/eid/2-s2.0-84934272190?view=FULL" 
      resp2 = requests.get(url, 
           headers={'Accept':'application/json', 
           'X-ELS-APIKey': MYAPIKEY}) 

      retrieval = resp2.json() 

      dep = retrieval['abstracts-retrieval-response']['item']['bibrecord']['head']['author-group'] 
      sub = retrieval['abstracts-retrieval-response']['subject-areas']['subject-area'] 
      iD = retrieval['abstracts-retrieval-response']['coredata']['intid'] 
      date = retrieval['abstracts-retrieval-response']['coredata']['prism:coverDate'] 

      department.append(dep) 
      subj.append(sub) 
      ident.append(iD) 
      dates.append(date) 

      break # Don't do the else 

     except Exception as exception: 
      print ('Problem accessing: {}' .format (url)) 
      print (exception) 
      time.sleep (2) # Seconds 
    else: # Done after for-loop exhausted, but not if 'break' was encountered 
     print ('Gave up accessing: {}' .format (url)) 

N.B. 나는 이것을 시험하지는 않았지만 일반적인 생각을 전달해야한다. 'sleep'은 서버가 숨을들이 쉬도록 허용하는 것입니다 ...
