httpclient get 请求+Body

正常情况下 基于HTTP规范 Get请求不应该包含请求正文 即 HttpClient 默认不支持在 GET(httpClient.GetAsync) 请求中发送带有 x-www-form-urlencoded 类型的请求正文

但是postman是支持的

且接收方可以从form中获取到body参数

//python
@app.route('/jiqingtest2', methods=['GET'])
def jiqingtest2():
    data = request.form.to_dict()
    print('data:', data)
    return jsonify(data)

如果想要与postman达到同样效果 则需要使用 httpclient.SendAsync(HttpRequestMessage )

 var formData = new List<KeyValuePair<string, string>>
        {
            new KeyValuePair<string, string>("param1", "value1"),
            new KeyValuePair<string, string>("param2", "value2")
        };
using (var client = new HttpClient(httpClientHandler))
{
    client.Timeout = new TimeSpan(0, 0, timeout); 
    var content = new FormUrlEncodedContent(formData);
    var req = new HttpRequestMessage() { Method = HttpMethod.Get,RequestUri=new Uri(url),Content=content };
    HttpResponseMessage response = await client.SendAsync(req);
    
}
