如何使用可重定向的反编译器cURL API? [英] How to use Retargetable Decompiler cURL API?

问题描述

我正在使用 Windows ，并且正在尝试使用这是使用可以正常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，出现错误.

I'm on Windows and I'm trying to use the cURL API provided by Retargetable Decompiler. Since cURL is a Linux utility, I downloaded a Windows build from here. Let's say I want to perform the following decompilation: This is using the browser which works and produces a result. Now when trying to do the same using cURL from the command line, I get errors.

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" }}

也是，code.bin与命令行(脚本)位于同一目录中.我该如何运作?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 进行解决可能更容易理解，因为没有提供了Java 示例或文档.

Also yes, the code.bin is in the same directory as the command line (script). How can I make it work? I actually prefer a solution in Java and not cURL but doing it in cURL first might be easier for understanding since no Java examples or documentation is provided.

推荐答案

没关系，这很简单.

开始该过程:

>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"

收到的(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"
    }
}
