如何构造HTTP GET请求以过滤JSON响应？

Question

我正在使用Curl发出以下HTTP GET请求：

卷曲http://rest.ensembl.org/variation/human/rs56116432?content-type=application

它返回以下JSON对象：

{"source":"Variants (including SNPs and indels) imported from dbSNP","mappings":[{"location":"9:133256042-133256042","assembly_name":"GRCh38","end":133256042,"seq_region_name":"9","strand":1,"coord_system":"chromosome","allele_string":"C/T","start":133256042},{"location":"CHR_HG2030_PATCH:133256189-133256189","assembly_name":"GRCh38","end":133256189,"seq_region_name":"CHR_HG2030_PATCH","strand":-1,"coord_system":"chromosome","allele_string":"C/T","start":133256189}],"name":"rs56116432","MAF":"0.00259585","ambiguity":"Y","var_class":"SNP","synonyms":[],"evidence":["Multiple_observations","Frequency","1000Genomes","ESP","ExAC"],"ancestral_allele":"C","minor_allele":"T","most_severe_consequence":"missense_variant"

是否可以构造HTTP请求，以便仅将键"most_severe_consequence"值返回给浏览器，而不是在返回请求后过滤数据？

API 文档不包含特定示例。

Answer 1

您可以添加查询参数，该参数需要响应的组成部分。

例如http://rest.ensembl.org/variation/human/rs56116432?content-type=application;bit_i_care_about=most_severe_consequence

另外，如果您只想要一个字段，则可以有一个额外的path元素。

http://rest.ensembl.org/variation/human/rs56116432/most_severe_consequence?content-type=application
