esp8266使用zlib库解压http gzip数据流并打印出来的程序

你可以参考以下代码：

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266HTTPClient.h>
#include <zlib.h>

void setup() {
  Serial.begin(115200);

  WiFi.begin("Your_SSID", "Your_PASSWORD");

  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }

  Serial.println("Connected to WiFi");
}

void loop() {
  if (WiFi.status() == WL_CONNECTED) {
    // obtain the http response from the server
    HTTPClient http;
    http.begin("http://example.com/data.gz");
    int httpResponseCode = http.GET();

    if (httpResponseCode == HTTP_CODE_OK) {
      // get the response payload
      String gzippedResponse = http.getString();

      // unpack the gzip response
      Bytef uncompressedData[1024];
      uLongf uncompressedSize = sizeof(uncompressedData);
      if (uncompress(uncompressedData, &uncompressedSize, (Bytef*)gzippedResponse.c_str(), gzippedResponse.length()) != Z_OK) {
        Serial.println("Failed to uncompress data");
      }

      // print the uncompressed data
      Serial.write(uncompressedData, uncompressedSize);
    } else {
      Serial.print("Error: ");
      Serial.println(httpResponseCode);
    }

    // close the http connection
    http.end();
  } else {
    Serial.println("WiFi not connected");
  }

  delay(5000);
}

这个程序将连接到Wi-Fi并从HTTP服务器获取gzip压缩的响应，解压缩并打印数据。请注意，我无法确保代码的正确性，因此建议您进行测试和调试。希望这可以回答您的问题！
