Qs.parse (), Qs.stringify (), Json.parse (), json.stringify () How to use

Json.parse (used to parse a JSON object from a String) PS: Single quotation mark written outside {}, each attribute must be double-quoted, otherwise an exception will be thrown

Let str = ' [{' field ': ' Thedate ', ' v1 ': ' 20170102 '},{' field ': ' Rev_type ', ' v1 ': ' Big Data revenue '},{' field ': ' Thismonth ', ' v1 ': ' 201708 "},{" field ":" Nextmonth "," V1 ":" 201709 "},{" field ":" Depart_type "," v1 ":" Leader "},{" field ":" admin_emp_id "," v1 ":" Role "}] ';

Json.parse (str);//str must satisfy the use of quotation marks, that is: double quotation marks and single quotation marks to each other nested

[

{field: "Thedate", v1: "20170102"},

< Span class= "object-value-string" >   { field:  "Rev_type",  v1:  "Big Data Revenue"},

< Span class= "object-value-string" >   { field:  "Thismonth",  V1:   "201708"},

< Span class= "object-value-string" >   { Field:  "Nextmonth",  v1: " 201709 "},

< Span class= "object-value-string" >   { Field:  "Depart_type",  v1: " Leader "},

< Span class= "object-value-string" >   { Field:  "admin_emp_id",  v1: " role "}

]

Second, json.stringify (used to parse the string from an object)

Let arr=[

{field: "Thedate", v1: "20170102"},

{field: "Rev_type", v1: "Big Data Revenue"},

< Span class= "object-value-string" >   { field:  "Thismonth",  V1:   "201708"},

< Span class= "object-value-string" >   { Field:  "Nextmonth",  v1: " 201709 "},

< Span class= "object-value-string" >   { Field:  "Depart_type",  v1: " Leader "},

< Span class= "object-value-string" >   { Field:  "admin_emp_id",  v1: " role "}

]

Json.stringify (arr);//All double quotes

"[{" Field ":" Thedate "," V1 ":" 20170102 "},{" field ":" Rev_type "," V1 ":" Big Data revenue "},{" field ":" Thismonth "," V1 ":" 201708 "},{" Field ":" Nextmonth "," V1 ":" 201709 "},{" field ":" Depart_type "," v1 ":" Leader "},{" field ":" admin_emp_id "," V1 ":" Role "}]"

Third, qs.parse () resolves the URL to the form of an object

Let URL = ' method=query_sql_dataset_data&projectid=85&apptoken=7d22e38e-5717-11e7-907b-a6006ad3dba0 '; Qs.parse (URL);//{method: "Query_sql_dataset_data", ProjectID: "$", Apptoken: "7d22e38e-5717-11e7-907b-a6006ad3dba0 "} IV, Qs.stringify () parses the object into the form of a URL let obj= {method:" Query_sql_dataset_data ", ProjectID:" $ ", Apptoken:" 7d22e38e-5717-11e7-907b-a6006ad3dba0 ", Datasetid:" 12564701 "};qs.stringify (obj)//{method:" Query_sql_dataset_data ", ProjectID:" Apptoken "," 7d22e38e-5717-11e7-907b-a6006ad3dba0 ", Datasetid:" 12564701 "}
