Ios CredStore 执行查询错误

发布于10月18日

我在对应用程序后端执行API调用时遇到问题，现在每次连接都会提示

CredStore - performQuery - Error copying matching creds.  Error=-25300, query={
    atyp = http;
    class = inet;
    "m_Limit" = "m_LimitAll";
    ptcl = http;
    "r_Attributes" = 1;
    srvr = "myappsurl.com";
    sync = syna;
}

我有点迷茫，因为我不确定这是什么原因，也不知道CredStore是怎么做的. CredStore在iOS中的作用是什么？

推荐答案

try 从URLCredentialStorage检索未知URLProtectionSpace的URLCredential时发生此错误. 例如:

let protectionSpace = URLProtectionSpace.init(host: host, 
                                              port: port, 
                                              protocol: "http", 
                                              realm: nil, 
                                              authenticationMethod: nil)

var credential: URLCredential? = URLCredentialStorage.shared.defaultCredential(for: protectionSpace)

生产

CredStore - performQuery - Error copying matching creds.  Error=-25300, query={
    class = inet;
    "m_Limit" = "m_LimitAll";
    ptcl = http;
    "r_Attributes" = 1;
    srvr = host;
    sync = syna;
}

为其提供保护空间的凭据:

let userCredential = URLCredential(user: user, 
                                   password: password, 
                                   persistence: .permanent)

URLCredentialStorage.shared.setDefaultCredential(userCredential, for: protectionSpace)

下次您try 检索凭据时，该错误将消失.
