如何在khttp中将原始byteArray发送为发布请求的主体?

从khttp的来源看来,您无法将原始byteArray作为请求正文发送,因为它总是向其中添加填充。我也尝试过使用Fuel库,但是它需要与我的依赖项冲突的协程。

有人知道如何1)在khttp中发送原始字节主体,或2)另一个这样做的库

您是对的。 As per their code如果您要发送的数据不是文件或流,它将是toString()'d,这不是您想要的。因此,您可以尝试提供ByteArrayInputStream而不是ByteArray

val response = post(
    "https://httpbin.org/anything",
    data = ByteArrayInputStream(byteArrayOf(1, 2, 3)),
    headers = mapOf("Content-Type" to "application/octet-stream")
)

因此,您将按原样发送字节。

顺便说一句,khttp repo似乎已被放弃,所以您最好切换到另一个库。基本上,任何HTTP库都可以发送原始字节。至于Fuel:它遵循模块化架构,不需要100%要求您使用协程:

val (request, response, result) = "https://httpbin.org/anything".httpPost()
    .body(byteArrayOf(1, 2, 3))
    .header(mapOf("Content-Type" to "application/octet-stream"))
    .response()

println(response)

您将看到您的字节数组(在data中):

<-- 200 (https://httpbin.org/anything)
Response : OK
Length : 564
Body : ({
    "args": {}, 
    "data": "\u0001\u0002\u0003", 
    "files": {}, 
    "form": {}, 
    "headers": {
        "Accept": "text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2", 
        "Accept-Encoding": "compress;q=0.5, gzip;q=1.0", 
        "Cache-Control": "no-cache", 
        "Connection": "close", 
        "Content-Length": "3", 
        "Content-Type": "application/octet-stream", 
        "Host": "httpbin.org", 
        "Pragma": "no-cache", 
        "User-Agent": "Java/1.8.0_192"
    }, 
    "json": null, 
    "method": "POST", 
    "origin": "1.2.3.4", 
    "url": "https://httpbin.org/anything"
})
