问题描述
我是 .netcore mvc 架构的新手.我正在尝试使用 api 数据响应，到目前为止我已成功获取数据，但我面临的问题是 api 响应/结果超过 1 时.例如，如果实际的 api 响应如下
"responseHeader":{状态":0，"QTime":0,参数":{"q":"title:\"A\""}},响应":{numFound":3，开始":0，文档":[{"日期":"1970-01-01T00:00:00Z","tstamp":"2019-11-22T12:22:31.698Z","摘要":"e23d679991d80d832504e7395d139fe4","contentLength":"25476",提升":0.0，"title":["emb- A1]"url":"https://www.example.com/a/b/c0/"},{"日期":"1970-01-01T00:00:00Z","tstamp":"2019-11-22T12:22:31.698Z","摘要":"e23d679991d80d832504e7395d139fe4","contentLength":"25476",提升":0.0，"title":["emb - A2]"url":"https://www.example.com/a/b/c1/"},{"日期":"1970-01-01T00:00:00Z","tstamp":"2019-11-22T12:22:31.698Z","摘要":"e23d679991d80d832504e7395d139fe4","contentLength":"25476",提升":0.0，"title":["emb - A3]"url":"https://www.example.com/a/b/c2/"}我只是得到
{"title":"[\r\n \"emb-A1","source":"https://www.example.com/a/b/c0/"}而不是拥有所有响应数据.
我的代码如下.型号SearchModel.cs

请帮忙..！
解决方案
如何检索从实际 API 获得的全部响应.
如果你想返回所有实际的 api 响应，那么只需使用以下代码:
[HttpGet("[action]/{query}")]公共异步任务产品(字符串查询){var model = new SearchModel();使用 (var client = new HttpClient()){尝试{client.BaseAddress = new Uri("http://xx.xx.xxx.xx:8080");var response = await client.GetAsync($"/abc/xxx/select?q=title%3A%22{query}%22");response.EnsureSuccessStatusCode();var stringResult = await response.Content.ReadAsStringAsync();var root = (JObject)JsonConvert.DeserializeObject(stringResult);返回新的 JsonResult(root);}catch (InvalidOperationException httpreq){}}返回确定()} 如果您只想从实际响应中返回 List，则不应使用 var data = k.Value.SelectToken("").Children().First(); 只会检索 docs 数组的第一个元素.
尝试 foreach k.Value.SelectToken("").Children() 并返回 List 而不是 SearchModel，参考
[HttpGet("[action]/{query}")]公共异步任务产品(字符串查询){//初始化一个列表搜索模型var modelList = new List();使用 (var client = new HttpClient()){尝试{client.BaseAddress = new Uri("http://xx.xx.xxx.xx:8080");var response = await client.GetAsync($"/abc/xxx/select?q=title%3A%22{query}%22");response.EnsureSuccessStatusCode();var stringResult = await response.Content.ReadAsStringAsync();var root = (JObject)JsonConvert.DeserializeObject(stringResult);var items = root.SelectToken("").Children().OfType().ToDictionary(p => p.Name, p => p.Value);foreach (var item in items){if (item.Key == "response"){var key = item.Value.SelectToken("").OfType().ToDictionary(p => p.Name, p => p.Value);foreach (var k in key){if (k.Key == "docs"){//删除.First()var arrayData = k.Value.SelectToken("").Children();foreach(arrayData 中的 var 数据){var model = new SearchModel();var test = data.SelectToken("").Children().OfType().ToDictionary(p => p.Name, p => p.Value).ToList();foreach(测试中的var t){if (t.Key == "url"){model.Source = t.Value.ToString();}else if (t.Key == "title"){模型.标题 = t.Value.ToString();}}模型列表.添加(模型)；}}}}}返回新的 JsonResult(modelList);}catch (InvalidOperationException httpreq){}}返回确定()；} I am new to .netcore mvc architecture. I am trying to consume the api data response, So far I have successfully fetched the data, but the problem I am facing is when the api response/result is more than one. Forexample if the actuall api response is the following
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"title:\"A\""}},
"response":{"numFound":3,"start":0,"docs":[
{
"date":"1970-01-01T00:00:00Z",
"tstamp":"2019-11-22T12:22:31.698Z",

"contentLength":"25476",
"boost":0.0,
"title":["emb- A1]
"url":"https://www.example.com/a/b/c0/"},
{
"date":"1970-01-01T00:00:00Z",

I am only getting

}
}
}
return new JsonResult(model);

How can I retrieve whole of the response I am getting from actual API.
Please help..!
解决方案
How can I retrieve whole of the response I am getting from actual API.
If you want to return all the actual api response,then just use below code:
[HttpGet("[action]/{query}")]
public async Task<IActionResult> Product(string query)
{
var model = new SearchModel();
using (var client = new HttpClient())
{
try
{
client.BaseAddress = new Uri("http://xx.xx.xxx.xx:8080");
var response = await client.GetAsync($"/abc/xxx/select?q=title%3A%22{query}%22");
response.EnsureSuccessStatusCode();
var stringResult = await response.Content.ReadAsStringAsync();
var root = (JObject)JsonConvert.DeserializeObject(stringResult);
return new JsonResult(root);
}
catch (InvalidOperationException httpreq)
{
}
}
return Ok()
}
If you would like to just return List<SearchModel> from the actual response,you should not use var data = k.Value.SelectToken("").Children().First(); which will only retrieve the first element of docs array.
Try to foreach k.Value.SelectToken("").Children() and return List<SearchModel> instead of a SearchModel,refer to
[HttpGet("[action]/{query}")]
public async Task<IActionResult> Product(string query)
{
//initialize a list SearchModel
var modelList = new List<SearchModel>();
using (var client = new HttpClient())
{
try
{
client.BaseAddress = new Uri("http://xx.xx.xxx.xx:8080");
var response = await client.GetAsync($"/abc/xxx/select?q=title%3A%22{query}%22");
response.EnsureSuccessStatusCode();
var stringResult = await response.Content.ReadAsStringAsync();
var root = (JObject)JsonConvert.DeserializeObject(stringResult);
var items = root.SelectToken("").Children().OfType<JProperty>().ToDictionary(p => p.Name, p => p.Value);
foreach (var item in items)
{
if (item.Key == "response")
{
var key = item.Value.SelectToken("").OfType<JProperty>().ToDictionary(p => p.Name, p => p.Value);
foreach (var k in key)
{
if (k.Key == "docs")
{
//remove .First()
var arrayData = k.Value.SelectToken("").Children();
foreach(var data in arrayData)
{
var model = new SearchModel();
var test = data.SelectToken("").Children().OfType<JProperty>().ToDictionary(p => p.Name, p => p.Value).ToList();
foreach (var t in test)
{
if (t.Key == "url")
{
model.Source = t.Value.ToString();
}
else if (t.Key == "title")
{
model.Title = t.Value.ToString();
}
}
modelList.Add(model);
}
}
}
}
}
return new JsonResult(modelList);
}
catch (InvalidOperationException httpreq)
{
}
}
return Ok();
}
