我正在尝试调用使用Oauth2密码凭据来获取身份验证令牌的第三方服务。芭蕾舞女演员正在回复以下消息。

Fault name : RF.Raise-406-Exception","detail":{"errorcode":"steps.raisefault.RaiseFault"}}}406代码让我感到困惑,因为我已经将内容类型和accept标头都设置为"application/json“,这正是服务所需的。然而,第二条消息显示“未能生成OAuth令牌”,那么会不会是获取OAuth2令牌的调用返回了406值呢?如果是这样,我如何在令牌服务调用上设置accept标头?
使用Ballerina,我已经调用了令牌端点并成功地获得了令牌,但是如果我尝试使用PasswordGrantConfig调用服务,这些就是我得到的错误。我已经尝试了我能想到的所有方法,并成功地让其他使用ClientCredentialsGrantConfig的服务正常工作。感谢您给予的任何帮助。
相关代码如下。下面的三个部分是三个不同.bal文件中的代码部分。
// configure the Oauth2 Config
import ballerina/config;
import ballerina/http;
import ballerina/oauth2;
public function getOauth2Handler() returns http:BearerAuthHandler {
oauth2:PasswordGrantConfig passwordGrantConfig = {
tokenUrl: config:getAsString("experian.authentication.tokenUrl"),
username: config:getAsString("experian.authentication.username"),
password: config:getAsString("experian.authentication.password"),
clientId: config:getAsString("experian.authentication.clientId"),
clientSecret: config:getAsString("experian.authentication.clientSecret"),
credentialBearer: http:AUTH_HEADER_BEARER
};
oauth2:OutboundOAuth2Provider oauth2Provider = new (passwordGrantConfig);
return new (oauth2Provider);
}
// Configure the API Client
http:ClientConfiguration delphiSelectClientConfig = {
auth: {
authHandler: experian:getOauth2Handler()
}
};
experian:DelphiSelectClientConfig delphiSelectConfig = {
serviceUrl: config:getAsString("experian.services.delphi-select.serviceUrl"),
clientConfig: delphiSelectClientConfig
};
experian:DelphiSelectClient delphiSelectClient = new (delphiSelectConfig);
// Call the endpoint using the Oath2 configuration
import ballerina/http;
import ballerina/io;
public type DelphiSelectClientConfig record {
string serviceUrl;
http:ClientConfiguration clientConfig;
};
//==============================
//============Client============
//==============================
public type DelphiSelectClient client object {
public http:Client clientEp;
public http:ClientConfiguration config;
public function __init(DelphiSelectClientConfig config) {
http:Client httpEp = new (config.serviceUrl, {auth: config.clientConfig.auth});
self.clientEp = httpEp;
self.config = config.clientConfig;
}
public remote function newApplication() returns @untainted json|error {
io:println("In newApplication function");
http:Request request = new;
json requestBody = newApplicationBody; // get test data from json in another file
request.setJsonPayload(requestBody);
var response = check self.clientEp->post("/application", request);
var payload = check response.getJsonPayload();
return payload;
}
};我还修改了测试代码以调用标记EP,并故意将accept设置为不可接受的值,例如"text/csv"。在这种情况下,我得到了相同的错误响应。但是,将accept设置为"*/*"确实有效。最后的测试;""的accept (空)也失败了,所以我怀疑BearerAuthHandler没有为accept设置任何值。
那么,我是否可以强制BearerAuthHandler将accept设置为"application/json"
谢谢。见下图。

此外,您引用的Oath2规范中的示例显示了正在设置的内容类型值。即使值为“*/*”也可以工作,但我怀疑Ballerina将其留空。我已经提出了GitHub问题Need to be able to set http header values for OutboundOAuth2Provider

http:OutboundAuthHandler对象的主要目的是准备带有身份验证信息的http:Request,这些信息需要通过您调用的外部端点进行身份验证。
http:BearerAuthHandler负责添加具有Bearer <token>值的Authorization报头。"token“是用提供的信息准备的。因此,没有强制http:BearerAuthHandler为请求设置任何标头的选项。
但在这种情况下,如果接口成功响应,且存在值为application/json的Accept header,则只需在调用POST请求之前将该header添加到http:Request中,如下所示:
request.addHeader("Accept", "application/json");
