ios - 请求与 postman 正常工作，但在使用 iOS 请求时因协议(protocol)错误而失败
<p><p>我正在尝试运行此请求，我这样做的原因是，我想在循环中使用不同的字符串测试推送通知(<em>我的意思是很多</em>)。 </p>
<p>当我尝试使用 <strong>Postman</strong> 执行此操作时，它运行良好我的意思是我尝试发送 300 个请求并且它们运行良好，但是当我使用 <strong> 执行此操作时请求出错URLSession</strong>.</p>
<p>我在控制台上遇到的错误是-
<code>
数据任务中有错误
操作无法完成。协议(protocol)错误

<p>我发送请求的代码是 - </p>
<pre><code> func testNotifications(times: Int, completionHandler: @escaping (String) -> Void) {
print("test notifications called")
let url = "https://fcm.googleapis.com/fcm/send"
var urlRequest = URLRequest(url: URL(string: url)!)
urlRequest.httpMethod = "POST"
let session = URLSession(configuration: .ephemeral)
urlRequest.setValue("Content-Type", forHTTPHeaderField: "application/json")
urlRequest.setValue("Authorization", forHTTPHeaderField: "Key=my_API_KEY")
do{
let jsonData = try JSONSerialization.data(withJSONObject: notificationJson, options: .prettyPrinted)
urlRequest.httpBody = jsonData

print("error is", err.localizedDescription)

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您的标题不正确。您应该像这样交换键值对:</p>
<pre><code>urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
urlRequest.setValue("Key=my_API_KEY", forHTTPHeaderField: "Authorization")
</code></pre></p>
