OHHTTPStubs测试请求是否包含cookie

Question

我正在尝试使用OHHTTPStubs测试我的HTTP请求是否包含cookie。不幸的是，我发现我的存根无法到达Cookie标头。

我的测试非常简单：

func test001_GET_WithSetCookie() {


    let stubResponse = self.expectation(description: "Server stub response successful")

    OHHTTPStubs.removeAllStubs()
    OHHTTPStubs.stubRequests(passingTest: {
        request in
            let requestHeaders = request.allHTTPHeaderFields
            NSLog("REQUEST ====> all header fields are: \(requestHeaders)") // I am expecting cookie header here, while performing second request;
            NSLog("REQUEST ====> Shared cookies at start: \(self.cookieStorage.cookies?.count)")
        return true

    }) { (URLRequest) -> OHHTTPStubsResponse in
        let localResponseHeaders = [
            "Content-Type" : "text/html;charset=ISO-8859-1",
            "Connection" : "keep-alive",
            "Expires" : "Tue, 1 Jan 2036 18:43:49 GMT",
            "Cache-Control" : "max-age=0",
            "Location" : "http://my-stub.com",
            "Server" : "openresty/1.9.3.1",
            "Set-Cookie" : "testCookie1=Oreo; expires=Wed, 23 Oct 2030 11:32:59 GMT; path=/; domain=my-stub.com"
        ]

        stubResponse.fulfill()
        return OHHTTPStubsResponse(data: Data(), statusCode: TestHttpResponse.ok.httpCode, headers: localResponseHeaders)
    }

    self.deleteAllStoredCookies()

    let url_A = URL(string: "http://my-stub.com/hello.html")!
    let url_B = URL(string: "http://my-stub.com/bye.html")!
    var request_A = URLRequest(url: url_A)
    request_A.httpMethod = "GET"
    request_A.cachePolicy = .reloadIgnoringLocalCacheData

    var request_B = URLRequest(url: url_B)
    request_B.httpMethod = "GET"
    request_B.cachePolicy = .reloadIgnoringLocalCacheData

    let getRequestExpectationA = self.expectation(description: "Server GET request successful")

    let getDataTaskA = URLSession.shared.dataTask(with: request_A, completionHandler: {
        (data, response, error) in
        XCTAssertNil(error, "Error occured while completing the request")
        XCTAssertTrue((response as! HTTPURLResponse).statusCode == TestHttpResponse.ok.httpCode, "Request didn't complete succesfully.")
        getRequestExpectationA.fulfill()
    })

    getDataTaskA.resume()

    self.asyncWaitForExpectations(timeout: 30, handler: {
        error in
        if (error != nil) {
            NSLog("Timeout error: \(error)")
        }
    })

    /*
        MARK: First request complete
     */
    let getRequestExpectationB = self.expectation(description: "Server GET request successful")

    let getDataTaskB = URLSession.shared.dataTask(with: request_B, completionHandler: {
        (data, response, error) in
        XCTAssertNil(error, "Error occured while completing the request")
        XCTAssertTrue((response as! HTTPURLResponse).statusCode == TestHttpResponse.ok.httpCode, "Request didn't complete succesfully.")
        getRequestExpectationB.fulfill()
    })

    getDataTaskB.resume()

    self.asyncWaitForExpectations(timeout: 30, handler: {
        error in
        if (error != nil) {
            NSLog("Timeout error: \(error)")
        }
    })

}

func deleteAllStoredCookies() {
    let cookies = cookieStorage.cookies;
    cookies?.forEach({
        cookie in
        NSLog("Deleting Cookie: \(cookie.name), domain=\(cookie.domain), path=\(cookie.path), expires=\(cookie.expiresDate)")
        cookieStorage.deleteCookie(cookie)
    })
}

在我看到的日志中，存根内部没有检索到标头：

我试图执行相同的测试，涉及本地主机服务器而不是OHHTTP存根，并且可以在执行第二个请求时在服务器端检索cookie。
