如何解码API返回的Gzip压缩Payload以获取二维矩阵

核心逻辑 #

1. 将API返回的payload一维整数数组转换为字节流
2. 使用Gzip算法解压字节流
3. 将解压后的数据解析为目标二维矩阵（通常是JSON格式，或按特定二进制规则解析）

Python 实现示例 #

import gzip
import json
from io import BytesIO

# API返回的响应数据
api_response = {
    "isPacked": True,
    "payload": [31,139,8,0,0,0,0,0,0,3,117,83,205,110,219,48,12,126,23,158,221,64,146,37,89,214,109,43,48,160,91,119,217,114,105,135,98,144,109,37,49,42,91,129,44,247,7,129,129,157,247,14,123,136,189,210,78,123,140,81,110,210,116,69,106,24,130,77,126,36,63,242,163,118,16,236,48,186,8,58,134,209,102,80,153,24,157,29,64,127,219,65,59,124,49,206,61,30,92,171,224,187,75,95,163,75,240,140,82,89,226,193,213,77,6,209,31,205,76,169,140,146,156,160,185,29,222,127,0,189,50,110,192,224,239,109,3,26,36,167,194,212,149,170,234,138,42,33,75,153,19,129,73,40,100,208,153,80,111,150,143,91,11,90,100,112,219,246,235,198,119,23,115,80,174,86,68,21,21,203,171,178,48,210,54,132,86,5,214,192,32,164,215,154,190,182,71,28,49,164,50,43,4,72,107,155,149,168,26,107,16,215,180,67,76,56,208,84,42,36,220,118,248,89,242,133,228,82,8,206,138,92,169,156,163,3,81,33,46,103,47,48,194,242,51,146,159,81,181,164,76,51,169,41,91,96,123,215,152,206,246,205,105,80,161,185,92,20,5,79,160,173,9,166,3,189,155,230,180,49,213,198,202,38,172,109,252,236,251,33,218,112,241,60,18,83,209,154,75,102,20,169,105,145,35,41,158,186,235,236,48,152,117,42,3,79,211,127,183,111,23,179,30,6,250,118,207,189,153,25,158,251,174,27,123,236,255,202,143,113,3,137,194,58,153,207,175,46,83,86,151,254,118,40,123,125,251,117,99,182,243,132,18,247,136,252,250,189,133,76,216,131,179,166,177,225,211,147,46,175,8,156,22,231,222,7,215,164,30,113,47,14,108,254,252,250,241,247,231,111,60,211,128,252,189,13,160,89,201,153,18,69,142,100,76,109,207,125,131,56,53,189,26,213,139,130,111,207,203,157,218,66,103,239,172,3,141,233,235,57,53,42,70,240,165,71,129,224,206,184,49,121,4,193,231,63,185,236,195,182,13,182,121,41,116,185,36,60,9,141,219,32,11,113,13,83,90,221,135,101,240,126,139,183,134,150,115,146,180,252,31,125,219,167,208,253,5,232,199,238,25,196,36,225,101,57,221,76,255,0,85,168,136,227,126,3,0,0]
}

# 1. 将payload数组转换为字节对象
compressed_bytes = bytes(api_response["payload"])

# 2. Gzip解压
with gzip.GzipFile(fileobj=BytesIO(compressed_bytes), mode='rb') as f:
    decompressed_data = f.read()

# 3. 解析为二维矩阵（假设解压后是JSON格式的字符串）
matrix = json.loads(decompressed_data.decode('utf-8'))

print(matrix)
