我正在尝试使用 AlamoFire 和以下代码发布到 Watson 音调分析器 API。它不断收到 401 错误,这显然意味着授权失败。但是,相同的用户 ID/密码信息适用于 curl 请求。所以问题似乎不在于用户名/密码,而在于我如何形成 AlamoFire 请求。
func postToWatson () {
print("post to watson called")
let url: String = "https://gateway.watsonplatform.net/tone-analyzer/api/v3/tone?version=2016-05-19"
let message = "All you need is love"
var parameters = [
"username":"my-lengthy-username",
"password":"my-ugly-password"]
parameters["text"] = message
Alamofire.request(url, parameters: parameters)
.responseJSON { response in
print(response.request)
print(response.response)
print(response.result)
}
}
以下是我通过上述打印命令从 API 返回的内容:
Optional(https://gateway.watsonplatform.net/tone-analyzer/api/v3/tone?version=2016-05-19&password=xxxxxx&text=All%20you%20need%20is%20love&username=xxxxxxxxxxxx)
Optional(<NSHTTPURLResponse: 0x1740396a0> { URL: https://gateway.watsonplatform.net/tone-analyzer/api/v3/tone?version=2016-05-19&password=xxxxxx&text=All%20you%20need%20is%20love&username=xxxxxxxxxxxx } { status code: 401, headers {

"X-Global-Transaction-ID" = ffea405d5b0ede123cd49ae1;

} })
SUCCESS
上面的代码有什么问题?
