当我尝试通过传递集成 ID 访问 Xcode 服务器代码覆盖率 API 时,它不是 JSON 响应,而是直接下载 .bz2 文件。我想使用此 API 在我的自定义仪表板中显示文件明智的覆盖率报告。
有什么方法可以让我从此 API ( https://developer.apple.com/library/content/documentation/Xcode/Conceptual/XcodeServerAPIReference/CodeCoverage.html ) 而不是 .bz2 文件获得 JSOn 响应?
最佳答案
不幸的是,API 只返回 .bz2 压缩的 JSON 文件。 即使指定 Accept=application/json 的 HTTP header 。
解决此问题的唯一方法是解压缩数据以访问底层 JSON。
这是一个使用框架 BZipCompression 在 iOS/swift 上看起来像的例子解压缩数据流:
import Foundation
import BZipCompression
public class Coverage {
public typealias CoverageCompletion = (_: Data?, _: Error?) -> Void
public enum Errors: Error {
case invalidURL
case invalidResponse
case invalidStatusCode
case invalidData
}
static var session: URLSession {
let session = URLSession(configuration: URLSessionConfiguration.default, delegate: LocalhostSessionDelegate.default, delegateQueue: nil)
return session
}
static public func coverage(forIntegrationWithIdentifier identifier: String, completion: @escaping CoverageCompletion) {
guard let url = URL(string: "https://localhost:20343/api/integrations/\(identifier)/coverage") else {
completion(nil, Errors.invalidURL)
return
}
let request = URLRequest(url: url)
let task = session.dataTask(with: request) { (data, response, error) in
guard error == nil else {
completion(nil, error)
return
}
guard let urlResponse = response as? HTTPURLResponse else {
completion(nil, Errors.invalidResponse)
return
}
guard urlResponse.statusCode == 200 else {
completion(nil, Errors.invalidStatusCode)
return
}
guard let d = data else {
completion(nil, Errors.invalidData)
return
}
var decompressedData: Data
do {
decompressedData = try self.decompress(data: d)
} catch let decompressionError {
completion(nil, decompressionError)
return
}
completion(decompressedData, nil)
}
task.resume()
}
static internal func decompress(data: Data) throws -> Data {
let decompressedData = try BZipCompression.decompressedData(with: data)
guard let decompressedString = String(data: decompressedData, encoding: .utf8) else {
throw Errors.invalidData
}
guard let firstBrace = decompressedString.range(of: "{") else {
throw Errors.invalidData
}
guard let lastBrace = decompressedString.range(of: "}", options: .backwards, range: nil, locale: nil) else {
throw Errors.invalidData
}
let range = decompressedString.index(firstBrace.lowerBound, offsetBy: 0)..<decompressedString.index(lastBrace.lowerBound, offsetBy: 1)
let json = decompressedString.substring(with: range)
guard let validData = json.data(using: .utf8) else {
throw Errors.invalidData
}
return validData
}
}
/// Class implementing the NSURLSessionDelegate which forcefully bypasses untrusted SSL Certificates.
public class LocalhostSessionDelegate: NSObject, URLSessionDelegate {
static public var `default` = LocalhostSessionDelegate()
// MARK: - NSURLSessionDelegate
@objc open func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
guard challenge.previousFailureCount < 1 else {
completionHandler(.cancelAuthenticationChallenge, nil)
return
}
var credentials: URLCredential?
if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust {
if let serverTrust = challenge.protectionSpace.serverTrust {
credentials = URLCredential(trust: serverTrust)
}
}
completionHandler(.useCredential, credentials)
}
}
我注意到解压后的数据通常在有效的 JSON block 的开头和结尾处包含无效的控制字符和其他垃圾。 decompress() 在完成 block 中返回之前清理数据。
您可能想查看我的 swift XCServerAPI GitHub 上的框架。我将使用这个确切的解决方案添加代码覆盖率端点。
