我正在使用alamofire从swift发送一个http发布请求:
let url = userActivity.webpageURL
if(url?.description.contains(UniversalLinkHandler().urlPrefix))!
{
let keystore = try! EtherKeystore()
let signedOrder = UniversalLinkHandler().parseURL(url: (url?.description)!)
let signature = signedOrder.signature.substring(from: 2)
let parameters: Parameters = [
"address" : keystore.recentlyUsedWallet?.address.description,
"indices": signedOrder.order.indices,
"v" : signature.substring(from: 128),
"r": signature.substring(from: 0, to: 64),
"s": signature.substring(from: 64, to: 128)
]
let query = UniversalLinkHandler.paymentServer
Alamofire.request(
query,
method: .post,
parameters: parameters
).responseJSON {
result in
print(result)
}
}
索引在调试器中显示为普通的UInt16数组,但是当发送到服务器时,它表示不存在索引数组
服务器在Java中,并使用springboot:
@RequestMapping(value = "/claimToken", method = RequestMethod.POST)
public ResponseEntity getAToken(@RequestParam(value="address") String address,
@RequestParam(value="indices") int[] indices,
@RequestParam(value = "v") byte v,
@RequestParam(value = "r") String r,
@RequestParam(value = "s") String s
)
第一个参数地址可以正常工作,但不适用于索引的int []数组
任何帮助深表感谢。
最佳答案
因为是导致问题的原因是您的signedOrder.order.indices
数组,并且它是[UInt16]
类型,所以我的建议是:
let indices = signedOrder.order.indices.map(Int.init)
let parameters: Parameters = [
"address" : keystore.recentlyUsedWallet?.address.description,
"indices": indices,
"v" : signature.substring(from: 128),
"r": signature.substring(from: 0, to: 64),
"s": signature.substring(from: 64, to: 128)
]
映射到
Int
可能会很好地解决您的问题。
