Question

------更新能够使用UsernamePasswordCredentials类来修复它代码如下所示 val client = new DefaultHttpClient client.getCredentialsProvider（）。setCredentials（AuthScope.ANY，new UsernamePasswordCredentials（“user”，“password”））;

我正在尝试对Restful API进行HttpPost调用，它期望用户名/密码，如何传递这些参数？我试过两种方式

post.addHeader("Username","user")
post.addHeader("Password","clear pwd")
and 
post.addHeader("Authorization","Basic base64encoded username:password")

没有效果，我将响应文字作为

响应文本= HTTP / 1.1 401未经授权[WWW-Authenticate：Digest realm =“API Realm”，domain =“/ default-api”，nonce =“pOxqalJKm5L5QXiphgFNmrtaJsh + gU”，algorithm = MD5，qop =“auth” ，stale = true，Content-Type：text / html; charset = ISO-8859-1，Cache-Control：必须重新验证，no-cache，no-store，Content-Length：311] org.apache.http.conn.BasicManagedEntity@5afa04c

以下是我的代码

val url = "http://restapi_url";
val post = new HttpPost(url)

//post.addHeader("Authorization","Basic QWBX3VzZXI6Q0NBQGRidHMxMjM=")
post.addHeader("Username","user_user")
post.addHeader("Password","clear pwd")
post.addHeader("APPLICATION_NAME","DO")
val fileContents = Source.fromFile("input.xml").getLines.mkString
post.setHeader("Content-type", "application/xml")
post.setEntity(new StringEntity(fileContents))

val response = (new DefaultHttpClient).execute(post)

println("Response Text = "+response.toString())

// print the response headers
println("--- HEADERS ---")
response.getAllHeaders.foreach(arg => println(arg))

Answer 1

您可以这样编写，它可以在我的程序中工作

import java.util.Base64

httpPost.addHeader("Authorization", "Basic " + Base64.getUrlEncoder.encodeToString("[your-username]:[your-password]".getBytes))

Answer 2

DefaultHttpClient已过时。您应该改用BasicCredentialsProvider。下面的示例代码：

val username = "your_username"
val password = "your_password"

    val credentialsProvider = new BasicCredentialsProvider()
    credentialsProvider.setCredentials(
      AuthScope.ANY,
      new UsernamePasswordCredentials(username, password)
    )

val httpClient =  HttpClientBuilder.create().setDefaultCredentialsProvider(credentialsProvider).build()

Answer 3

此处的授权标头应按以下方式计算：

httpPost.addHeader("Authorization", "Basic " + Base64.getEncoder.encodeToString("[your-username]:[your-password]".getBytes))

它应该是getEncoder（），而不是getUrlEncoder（）。
