将图像上传到 OCR Microsoft Vision 时出现 401 错误 API

Question

我正在学习 objective-C，我正在尝试将图片上传到 microsoft vision api

我已经将它们用作 headers

    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPMethod:@"POST"];
    [request addValue:@"{*************}" forHTTPHeaderField:@"Ocp-Apim-Subscription-Key"];

我从服务器收到这条消息

{ "statusCode": 401, "message": "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription." }

我已经尝试重新生成密钥，我很确定我使用的是正确的密钥。

Answer 1

你需要去掉花括号，具体来说：

[request addValue:@"*************" forHTTPHeaderField:@"Ocp-Apim-Subscription-Key"];
