linux - 如何使用可重定向反编译器 cURL API？

Question

我在 Windows 上，我正在尝试使用 cURL API由 Retargetable Decompiler 提供。由于 cURL 是一个 Linux 实用程序，我从 here 下载了一个 Windows 版本。 .假设我要执行以下反编译: 这是使用可以工作并产生结果的浏览器。现在，当尝试从命令行使用 cURL 执行相同操作时，我收到错误。

输出:

>curl --form "mode=raw" --form "input=code.bin" --form "architecture=powerpc" --form "endian=big" --form "raw_entry_point=0x0" --form "raw_section_vma=0x0" -u my-secret-api-key: "https://retdec.com/service/api/decompiler/decompilations" { "id": "yVWe4pe5", "links": { "decompilation": "https://retdec.com/service/api/decompiler/decompilations/yVWe4pe5", "status": "https://retdec.com/service/api/decompiler/decompilations/yVWe4pe5/status", "outputs": "https://retdec.com/service/api/decompiler/decompilations/yVWe4pe5/outputs" }}

    "message": "Method Not Allowed"
}
curl: (6) Could not resolve host: status
{
    "code": 404,
    "description": "The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.",
    "message": "Not Found"
}
curl: (6) Could not resolve host: outputs
{
    "code": 405,
    "description": "The method is not allowed for the requested URL.",
    "message": "Method Not Allowed"
}
curl: (3) [globbing] unmatched close brace/bracket in column 1

还有，code.bin 与命令行(脚本)位于同一目录中。我怎样才能让它发挥作用？ 我实际上更喜欢使用 Java 而不是 cURL 的解决方案，但是首先使用 cURL 可能更容易理解，因为没有 提供 Java 示例或文档。

没关系，这很简单。

开始进程:

>curl --form "mode=raw" --form "input=@code.bin;filename=code.bin" --form "architecture=powerpc" --form "endian=big" --form "raw_entry_point=0x0" --form "raw_section_vma=0x0" --form "target_language=c" -u my-secret-api-key: "https://retdec.com/service/api/decompiler/decompilations"

收到(示例)响应:

{
    "id": "mKgBoLa3jo",
    "links": {
        "decompilation": "https://retdec.com/service/api/decompiler/decompilations/mKgBoLa3jo",
        "outputs": "https://retdec.com/service/api/decompiler/decompilations/mKgBoLa3jo/outputs",
        "status": "https://retdec.com/service/api/decompiler/decompilations/mKgBoLa3jo/status"
    }
}

获取反编译(示例)代码:

>curl -u my-secret-api-key: https://retdec.com/service/api/decompiler/decompilations/r8OW7AaAOb/outputs/hll
