C#OAuth批处理多部分内容响应,如何获取所有内容而不是字符串对象

如何解决《C#OAuth批处理多部分内容响应,如何获取所有内容而不是字符串对象》经验,为你挑选了1个好方法。

我收到属于OAuth批处理请求的多部分内容响应:

// batchRequest is a HttpRequestMessage, http is an HttpClient
HttpResponseMessage response = await http.SendAsync(batchRequest);

如果我以全文形式阅读其内容:

string fullResponse = await response.Content.ReadAsStringAsync();

它包含以下内容:

--batchresponse_e42a30ca-0f3a-4c17-8672-22abc469cd16
Content-Type: application/http
Content-Transfer-Encoding: binary

HTTP/1.1 200 OK

Content-Type: application/json;odata=minimalmetadata;streaming=true;charset=utf-8

--batchresponse_e42a30ca-0f3a-4c17-8672-22abc469cd16

--batchresponse_e42a30ca-0f3a-4c17-8672-22abc469cd16--

我需要将所有这些内容作为对象(例如经典的HttpResponseMessage,而不是简单的字符串)来获取,以便将HTTP返回代码,JSON内容等作为属性并能够将其处理。

我知道如何分别阅读所有这些内容,但是我无法弄清楚如何将它们作为对象获取,我仅成功获取了字符串内容:

var multipartContent = await response.Content.ReadAsMultipartAsync();
foreach (HttpContent currentContent in multipartContent.Contents) {
     var testString = currentContent.ReadAsStringAsync();
     // How to get this content as an exploitable object?
}

在我的示例中,testString包含:

HTTP/1.1 200 OK
DataServiceVersion: 3.0;
Content-Type: application/json;odata=minimalmetadata;streaming=true;charset=utf-8

{\"odata.metadata\":\"https://graph.windows.net/XXX.onmicrosoft.com/$metadata#directoryObjects/@Element\",\"odata.type\":\"Microsoft.DirectoryServices.User\",\"objectType\":\"User\",\"objectId\":\"5f6851c3-99cc-4a89-936d-4bb44fa78a34\",\"deletionTimestamp\":null,\"accountEnabled\":true,\"signInNames\":[],\"assignedLicenses\":[],\"assignedPlans\":[],\"city\":null,\"companyName\":null,\"country\":null,\"creationType\":null,\"department\":\"NRF\",\"dirSyncEnabled\":null,\"displayName\":\"dummy1 Test\",\"facsimileTelephoneNumber\":null,\"givenName\":\"dummy1\",\"immutableId\":null,\"isCompromised\":null,\"jobTitle\":\"test\",\"lastDirSyncTime\":null,\"mail\":null,\"mailNickname\":\"dummy1test\",\"mobile\":null,\"onPremisesSecurityIdentifier\":null,\"otherMails\":[],\"passwordPolicies\":null,\"passwordProfile\":{\"password\":null,\"forceChangePasswordNextLogin\":true,\"enforceChangePasswordPolicy\":false},\"physicalDeliveryOfficeName\":null,\"postalCode\":null,\"preferredLanguage\":null,\"provisionedPlans\":[],\"provisioningErrors\":[],\"proxyAddresses\":[],\"refreshTokensValidFromDateTime\":\"2016-12-02T08:37:24Z\",\"showInAddressList\":null,\"sipProxyAddress\":null,\"state\":\"California\",\"streetAddress\":null,\"surname\":\"Test\",\"telephoneNumber\":\"666\",\"thumbnailPhoto@odata.mediaEditLink\":\"directoryObjects/5f6851c3-99cc-4a89-936d-4bb44fa78a34/Microsoft.DirectoryServices.User/thumbnailPhoto\",\"usageLocation\":null,\"userPrincipalName\":\"dummy1test@XXX.onmicrosoft.com\",\"userType\":\"Member\"}

我不能只想象手动解析此字符串...因此,如果有人有线索或可以向我解释读取内容的好方法,那将是很好的。

谢谢,马克斯



1> Max Xapi..:

这是可以完成的方法。关键是在响应中添加新的内容类型“ msgtype”标头:

var multipartContent = await response.Content.ReadAsMultipartAsync();
var multipartRespMsgs = new List();
foreach (HttpContent currentContent in multipartContent.Contents) {
    // Two cases:
    // 1. a "single" response
    if (currentContent.Headers.ContentType.MediaType.Equals("application/http", StringComparison.OrdinalIgnoreCase)) {
        if (!currentContent.Headers.ContentType.Parameters.Any(parameter => parameter.Name.Equals("msgtype", StringComparison.OrdinalIgnoreCase) && parameter.Value.Equals("response", StringComparison.OrdinalIgnoreCase))) {
            currentContent.Headers.ContentType.Parameters.Add(new NameValueHeaderValue("msgtype", "response"));
        }
        multipartRespMsgs.Add(await currentContent.ReadAsHttpResponseMessageAsync());
        // The single object in multipartRespMsgs contains a classic exploitable HttpResponseMessage (with IsSuccessStatusCode, Content.ReadAsStringAsync().Result, etc.)
    }
    // 2. a changeset response, which is an embedded multipart content
    else {
        var subMultipartContent = await currentContent.ReadAsMultipartAsync();
        foreach (HttpContent currentSubContent in subMultipartContent.Contents) {
            currentSubContent.Headers.ContentType.Parameters.Add(new NameValueHeaderValue("msgtype", "response"));
            multipartRespMsgs.Add(await currentSubContent.ReadAsHttpResponseMessageAsync());
            // Same here, the objects in multipartRespMsgs contain classic exploitable HttpResponseMessages
        }
    }
}
