Question

我很难完成字符串的所有JSON值，任何人都可以帮助我吗？我只得到一个单一的价值，我哪里错了？

我的代码

Dim address As String = "http://wsloterias.azurewebsites.net/api/sorteio/getresultado/1"
Dim client As WebClient = New WebClient()
Dim reader As StreamReader = New StreamReader(client.OpenRead(address))
Dim json = (reader.ReadToEnd)

Dim objs As RootObject = JsonConvert.DeserializeObject(Of RootObject)(json)
Dim objsSorteio As Sorteio = JsonConvert.DeserializeObject(Of Sorteio)(json)


For Each nums In objsSorteio.Premios
    MsgBox(nums.ToString)
Next

我无法通过所有“Numeros”和“Premios”

你不必要地使这种情况复杂化。

使用提供的URL，将公开的json数据复制并插入到http://jsonutils.com/等实用程序站点中。它生成了具有自动属性的模型。请注意，它将集合转换为数组，就像您在类中一样列入列表。

'''other code removed for brevity
Dim objs As RootObject = JsonConvert.DeserializeObject(Of RootObject)(json)
Dim objsSorteioList As List(Of Sorteio) = objs.Sorteios.ToList()

For Each objsSorteio In objsSorteioList
    For Each prems In objsSorteio.Premios
        MsgBox(prems.ToString)
    Next
    For Each nums In objsSorteio.Numeros
        MsgBox(nums.ToString)
    Next
Next

基本上与原来的相同，具有更好的可读性。如果这是您的偏好，请随意将数组转换回列表。

第一次反序化已经为你提供了必要的对象。深入了解属性以访问所需的值。

getAccountDetails(accountId: string): Promise<any> {
    let url = API_ENDPOINT + 'some-string';
    return new Promise(resolve => {
      this.userData.hasLoggedIn().then((hasLoggedIn) => {
        if (hasLoggedIn) {
          this.userData.getUserToken().then((token) => {
            let headers = new Headers();

            headers.append('Authorization', 'Bearer ' + token);

            this.http.post(url, { id: accountId }, { headers: headers }).map(res => res.json()).subscribe(data => {
              resolve(data);
            });
          })
        }
      })
    });
  }
