Kotlin+Retrofit上传文件报Parameter ty

采坑

附上参考链接，侵权即删：https://blog.csdn.net/janronehoo/article/details/88955273

上传图片接口NetService.kt中定义为

@Multipart

@POST(UrlDefinition.UPLOAD_IMAGE)

fun uploadImage(@PartMap map: Map<String, RequestBody>): Observable<NetResult<String>>

NetHelper中调用

fun uploadImage(file: File, length: Int, width: Int, callback: (String) -> Unit, netFinish: (String) -> Unit) {

val partMap = HashMap<String, RequestBody>()

val pic = RequestBody.create(MediaType.parse("multipart/form-data"), file)

partMap["file\";filename=\"" +"file.jpg"] = pic

val lengthBody = RequestBody.create(MediaType.parse("multipart/form-data"),"" + length)

val widthBody = RequestBody.create(MediaType.parse("multipart/form-data"),"" + width)

partMap["length"] = lengthBody

partMap["width"] = widthBody

netApi.uploadImage(partMap)

.asyncSchedulers()

.subscribe(object : BaseSubscribe>() {

override fun onNextData(mData: String) {

callback.invoke(mData)

}

override fun onErrorData(code: Int, msg: String) {

netFinish.invoke(msg)

}

})

}

结果报错：Parameter type must not include a type variable or wildcard

参照链接中说加入@JvmSuppressWildcards注解，测试对我这边无用，真正原因是定义接口fun uploadImage(@PartMap map: Map<String, RequestBody>)时用的是Map??调用时传入的是HashMap<String, RequestBody>()？？？

修改后NetService中上传接口

fun uploadImage(@PartMap map: HashMap<String, RequestBody>): Observable<NetResult<String>>

再次调用问题已解决。。。

才疏学浅，记一下采坑，个人猜想估计是Kotlin对类型要求比较严格？希望各位大佬留言解释下，万分感谢
