可以使用C或者C++的代码吗?

当然可以!以下是一个使用C语言读取jar文件并使用libdeflate库解压缩数据流的示例代码:
```c
#include <stdio.h>
#include <stdlib.h>
#include "libdeflate/libdeflate.h"
int main() {
// 读取jar文件
FILE *jarFile = fopen("example.jar", "rb");
if (!jarFile) {
printf("Failed to open jar file\n");
return 1;
}
// 获取jar文件大小
fseek(jarFile, 0, SEEK_END);
size_t fileSize = ftell(jarFile);
fseek(jarFile, 0, SEEK_SET);
// 分配缓冲区
char *compressedData = malloc(fileSize);
char *decompressedData = malloc(fileSize);
// 读取jar文件到缓冲区
fread(compressedData, 1, fileSize, jarFile);
// 使用libdeflate库解压缩数据流
struct libdeflate_decompressor *decompressor = libdeflate_alloc_decompressor();
size_t decompressedSize = libdeflate_zlib_decompress(decompressor, compressedData, fileSize, decompressedData, fileSize);
if (decompressedSize == 0) {
printf("Failed to decompress data\n");
return 1;
}
// 处理解压缩的数据流
// ...
// 释放缓冲区和解压缩器
free(compressedData);
free(decompressedData);
libdeflate_free_decompressor(decompressor);
// 关闭文件
fclose(jarFile);
return 0;
}
```
需要注意的是,上述代码假设您已经正确引入了libdeflate库,并且在编译时将其链接到了可执行文件中。另外,您可能需要根据您的具体需求对代码进行修改。
