Question

我有一个json字符串，我想要解析。

>>> test = json.dumps('{"content":{"search_highlight":{},"message_exchanged":{"messagesOnlyToViewee":true,"messagesOnlyToViewer":true},"Certifications":{"certsMpr":{},"empty":{}},"lix_treasury_callout":"B","network_overview":{"lix_deferLoad":"B","lix_showDetail":"control","distance":3,"lix_deferOnload":"B","allow_pivot_search":false,"i18n_S_NETWORK":"xyz\'s Network","facets":{"skill_explicit":{"data":[{"count":5,"name":"Equity Research","value":"2112"},{"count":5,"name":"Equities","value":"462"},{"count":5,"name":"Portfolio Management","value":"480"},{"count":4,"name":"Financial Markets","value":"1371"},{"count":4,"name":"Derivatives","value":"814"},{"count":3,"name":"Mutual Funds","value":"1043"},{"count":3,"name":"Financial Modeling","value":"1245"},{"count":3,"name":"MIS","value":"1303"},{"count":3,"name":"Negotiation","value":"256"},{"count":3,"name":"Trading","value":"283"}],"i18n_skill_explicit":"Skills"},"geo_region":{"data":[{"count":39,"name":"India","value":"in:0"},{"count":30,"name":"Mumbai Area, India","value":"in:7150"},{"count":1,"name":"Hyderabad Area, India","value":"in:6508"},{"count":1,"name":"Chandigarh Area, India","value":"in:6879"},{"count":1,"name":"Kolkata Area, India","value":"in:7003"},{"count":1,"name":"Moradabad Area, India","value":"in:7046"},{"count":1,"name":"Lucknow Area, India","value":"in:7093"},{"count":1,"name":"Bengaluru Area, India","value":"in:7127"},{"count":1,"name":"New Delhi Area, India","value":"in:7151"},{"count":1,"name":"Jaipur Area, India","value":"in:7287"}],"i18n_geo_region":"Location"},"current_company":{"data":[{"count":5,"name":"L&amp;T Mutual Fund","value":"919608"},{"count":2,"name":"IDFC","value":"21175"},{"count":1,"name":"Indiabulls","value":"10359"},{"count":1,"name":"Innodata Inc.","value":"10827"},{"count":1,"name":"Tangoe","value":"11341"},{"count":1,"name":"Philippine National Bank","value":"17277"},{"count":1,"name":"bc","value":"164575"},{"count":1,"name":"Metropolis Health Services (I) Ltd","value":"236316"},{"count":1,"name":"India Infoline Ltd","value":"239538"},{"count":1,"name":"Wadhwa Group","value":"312891"}],"i18n_current_company":"Company"},"education":{"i18n_education":"School","data":[{"count":8,"name":"University of Mumbai","value":"13663"},{"count":1,"name":"Anna University","value":"13412"},{"count":1,"name":"Jawaharlal Nehru Technological University","value":"13520"},{"count":1,"name":"Karnataka State Open University","value":"13530"},{"count":1,"name":"University of Allahabad","value":"13652"},{"count":1,"name":"University of Lucknow","value":"13661"},{"count":1,"name":"West Bengal University of Technology","value":"13686"},{"count":1,"name":"University of Calcutta","value":"20302"},{"count":1,"name":"Welingkar Institute of Management","value":"21296"},{"count":1,"name":"The Institute of Chartered Accountants of India","value":"22460"}]},"industry":{"data":[{"count":22,"name":"Financial Services","value":"43"},{"count":4,"name":"Human Resources","value":"137"},{"count":2,"name":"Real Estate","value":"44"},{"count":2,"name":"Information Technology and Services","value":"96"},{"count":2,"name":"Capital Markets","value":"129"},{"count":1,"name":"Telecommunications","value":"8"},{"count":1,"name":"Hospital &amp; Health Care","value":"14"},{"count":1,"name":"Banking","value":"41"},{"count":1,"name":"Investment Management","value":"46"},{"count":1,"name":"Education Management","value":"69"}],"i18n_industry":"Industry"}},"i18n_not_allow_conn_browse":"xyz does not allow connection browsing.","link__overview_detail":"/profile/profile\\u002dv2\\u002dnetwork\\u002doverview\\u002ddetail?id=131506997&srchFacet=search_facet_param&srchFacetValue=search_facet_value_param&facetResultCount=search_facet_count_param","i18n_count_string":"500+"}}}')
>>> test1 = json.dumps(test)
>>> test2 = json.loads(test1)

>>> test2['content']

Traceback (most recent call last):
  File "<pyshell#129>", line 1, in <module>
    test2['content']
TypeError: string indices must be integers

我不明白为什么会发生这个错误。如果我错过了什么，请告诉我。

Answer 1

您对JSON进行了三重编码，但只进行了一次解码。

在拥有可在json.loads()上编制索引的Python对象之前，您需要另外两个 'content'调用：

>>> test = json.dumps('{"content":{"search_highlight":{},"message_exchanged":{"messagesOnlyToViewee":true,"messagesOnlyToViewer":true},"Certifications":{"certsMpr":{},"empty":{}},"lix_treasury_callout":"B","network_overview":{"lix_deferLoad":"B","lix_showDetail":"control","distance":3,"lix_deferOnload":"B","allow_pivot_search":false,"i18n_S_NETWORK":"xyz\'s Network","facets":{"skill_explicit":{"data":[{"count":5,"name":"Equity Research","value":"2112"},{"count":5,"name":"Equities","value":"462"},{"count":5,"name":"Portfolio Management","value":"480"},{"count":4,"name":"Financial Markets","value":"1371"},{"count":4,"name":"Derivatives","value":"814"},{"count":3,"name":"Mutual Funds","value":"1043"},{"count":3,"name":"Financial Modeling","value":"1245"},{"count":3,"name":"MIS","value":"1303"},{"count":3,"name":"Negotiation","value":"256"},{"count":3,"name":"Trading","value":"283"}],"i18n_skill_explicit":"Skills"},"geo_region":{"data":[{"count":39,"name":"India","value":"in:0"},{"count":30,"name":"Mumbai Area, India","value":"in:7150"},{"count":1,"name":"Hyderabad Area, India","value":"in:6508"},{"count":1,"name":"Chandigarh Area, India","value":"in:6879"},{"count":1,"name":"Kolkata Area, India","value":"in:7003"},{"count":1,"name":"Moradabad Area, India","value":"in:7046"},{"count":1,"name":"Lucknow Area, India","value":"in:7093"},{"count":1,"name":"Bengaluru Area, India","value":"in:7127"},{"count":1,"name":"New Delhi Area, India","value":"in:7151"},{"count":1,"name":"Jaipur Area, India","value":"in:7287"}],"i18n_geo_region":"Location"},"current_company":{"data":[{"count":5,"name":"L&amp;T Mutual Fund","value":"919608"},{"count":2,"name":"IDFC","value":"21175"},{"count":1,"name":"Indiabulls","value":"10359"},{"count":1,"name":"Innodata Inc.","value":"10827"},{"count":1,"name":"Tangoe","value":"11341"},{"count":1,"name":"Philippine National Bank","value":"17277"},{"count":1,"name":"bc","value":"164575"},{"count":1,"name":"Metropolis Health Services (I) Ltd","value":"236316"},{"count":1,"name":"India Infoline Ltd","value":"239538"},{"count":1,"name":"Wadhwa Group","value":"312891"}],"i18n_current_company":"Company"},"education":{"i18n_education":"School","data":[{"count":8,"name":"University of Mumbai","value":"13663"},{"count":1,"name":"Anna University","value":"13412"},{"count":1,"name":"Jawaharlal Nehru Technological University","value":"13520"},{"count":1,"name":"Karnataka State Open University","value":"13530"},{"count":1,"name":"University of Allahabad","value":"13652"},{"count":1,"name":"University of Lucknow","value":"13661"},{"count":1,"name":"West Bengal University of Technology","value":"13686"},{"count":1,"name":"University of Calcutta","value":"20302"},{"count":1,"name":"Welingkar Institute of Management","value":"21296"},{"count":1,"name":"The Institute of Chartered Accountants of India","value":"22460"}]},"industry":{"data":[{"count":22,"name":"Financial Services","value":"43"},{"count":4,"name":"Human Resources","value":"137"},{"count":2,"name":"Real Estate","value":"44"},{"count":2,"name":"Information Technology and Services","value":"96"},{"count":2,"name":"Capital Markets","value":"129"},{"count":1,"name":"Telecommunications","value":"8"},{"count":1,"name":"Hospital &amp; Health Care","value":"14"},{"count":1,"name":"Banking","value":"41"},{"count":1,"name":"Investment Management","value":"46"},{"count":1,"name":"Education Management","value":"69"}],"i18n_industry":"Industry"}},"i18n_not_allow_conn_browse":"xyz does not allow connection browsing.","link__overview_detail":"/profile/profile\\u002dv2\\u002dnetwork\\u002doverview\\u002ddetail?id=131506997&srchFacet=search_facet_param&srchFacetValue=search_facet_value_param&facetResultCount=search_facet_count_param","i18n_count_string":"500+"}}}')

Answer 2

你抛弃了太多：

test1 = json.dumps(test)转储转储的字符串转储......您应该直接调用test2 = json.loads('{"content...)。

（如果你真的想要这个trpile-dumping出于任何原因，你需要test2 = json.loads(json.loads(json.loads(test1)))）

无法在python中解析json
