Java 客户端凭据流出现错误400
我正在尝试对客户端凭据流进行身份验证,但一直返回错误400。我查看了可用的API,但看不出我做错了什么。如果有人能给我一个正确的方向,那就太棒了。谢谢Java 客户端凭据流出现错误400,java,spotify,Java,Spotify,我正在尝试对客户端凭据流进行身份验证,但一直返回错误400。我查看了可用的API,但看不出我做错了什么。如果有人能给我一个正确的方向,那就太棒了。谢谢 package com.elliott.lyric.io; import org.apache.commons.codec.binary.Base64; import org.apache.http.*; import org.apache.http.client.HttpClient; import org.apache.http.clien

尝试以下更改请求
https://accounts.spotify.com/api/token
authorize()
,如下所示
void authorize() {
try {
authURL = "https://accounts.spotify.com/api/token";
String idSecret = clientID + ":" + secretID;
String idSecretEncoded = new String(Base64.encodeBase64(idSecret.getBytes()));
HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost(authURL);
post.setHeader("User-Agent", USER_AGENT);
post.setHeader("Content-Type", "application/x-www-form-urlencoded");
post.setHeader("Authorization", "Basic " + idSecretEncoded);
List<NameValuePair> urlParameters = new ArrayList<>();
urlParameters.add(new BasicNameValuePair("grant_type", "client_credentials"));
post.setEntity(new UrlEncodedFormEntity(urlParameters));
HttpResponse response = client.execute(post);
System.out.println("Response Code : " + response.getStatusLine().getStatusCode());

StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {

添加(新的BasicNameValuePair(“授权类型”、“客户端凭据”);

}非常感谢你,伙计。因此,我将auth放在了错误的位置,并误解了参数部分。所以它就像?授权=基本。。URL中的etc?您尝试将
授权
作为表单数据,将授权类型
作为查询参数:
