使用C＃HttpClient API和邮递员测试之间的区别？客户端调用适用于邮递员，但不适用于C＃httpClient getAsync

本文介绍了使用C＃HttpClient API和邮递员测试之间的区别？客户端调用适用于邮递员，但不适用于C＃httpClient getAsync的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在测试REST API帖子，并且在Postman上尝试时效果很好。但是，在某些情况下（与发布XML数据有关），如果我使用HttpClient API进行发布，则会收到以下错误：

I am testing a REST API post, and it works well when I try it on Postman. However, in some scenario (related to the posting XML data) if I post with HttpClient API, I would receive the following error:

但是相同的XML内容在邮递员的状态为OK且响应正确。

But the same XML content works fine on Postman with status OK and proper response.

使用C＃HttpClient API和邮递员测试之间有什么区别？如何配置我的API调用以使其与邮递员的行为相匹配？

What is the differences between using the C# HttpClient API and the postman testing? How can I configure my API call to match with the behavior on postman?

在这里我附上了源代码和邮递员屏幕截图

Here I attached the source code, and the Postman screenshot

public void createLoan()
{
    string baseCreateLoanUrl = @"https://serverhost/create?key=";
    var strUCDExport = XDocument.Load(@"C:\CreateLoan_testcase.xml");

    using (var client = new HttpClient())
    {
        var content = new StringContent(strUCDExport.ToString(), Encoding.UTF8, Mediatype);
        string createLoanApi = string.Concat(baseCreateLoanUrl, APIKey);

        try
        {
            var response = client.PostAsync(createLoanApi, content).Result;
        }
        catch (Exception ex)
        {
            MessageBox.Show("Error Happened here...");
            throw;
        }

        if (response.IsSuccessStatusCode)
        {
            // Access variables from the returned JSON object
            string responseString = response.Content.ReadAsStringAsync().Result;
            JObject jObj = JObject.Parse(responseString);

            if (jObj.SelectToken("failure") == null)
            {
                // First get the authToken
                string LoanID = jObj["loanStatus"]["id"].ToString();
                MessageBox.Show("Loan ID: " + LoanID);
            }
            else
            {
                string getTokenErrorMsg = string.Empty;

                JArray errorOjbs = (JArray) jObj["failure"]["errors"];
                foreach (var errorObj in errorOjbs)
                {
                    getTokenErrorMsg += errorObj["message"].ToString() + Environment.NewLine;
                }
                getTokenErrorMsg.Dump();
            }
        }
    }

推荐答案

感谢Nard的评论，比较标题后，我发现我的客户标题有以下问题：
期望：100-继续

Thanks for Nard's comment, after comparing the header, I found the issue my client header has this:Expect: 100-continue

而邮递员

一旦我使用ServicePointManager删除了它：

Once I removed this by using the ServicePointManager:

ServicePointManager.Expect100Continue = false;

现在一切似乎都很好。感谢所有输入！

Everything seems fine now. Thanks all the input!
