关闭上个月。

[两个不同的API的数据就像Array1和Array2

Array1 =

[{"ID" : 1  ,"Name": "abc" , "FamilyName" , "Grimes" },{"ID" : 2 ,"Name": "bcd" , "FamilyName" , "Grimes" }]

Array2 =

[{"ID" : 3  ,"Name": "efc" , "FamilyName" , "Grimes" },{"ID" : 4 ,"Name": "hij" , "FamilyName" , "Grimes" }]

预期输出：

 [{"ID" : 1  ,"Name": "abc" , "FamilyName" , "Grimes" },
  {"ID" : 2 ,"Name": "bcd" , "FamilyName" , "Grimes" },
  {"ID" : 3  ,"Name": "efc" , "FamilyName" , "Grimes" },
  {"ID" : 4 ,"Name": "hij" , "FamilyName" , "Grimes" }]

Answer 1

const expected = [...array1, ...array2];

Answer 2

您可以选择使用forkJoin：

const books = this.http.getbooks();
const authors = this.http.getauthors();

forkJoin([books, authors]).subscribe(response => {
 // response[0] will be req1 response
 // response[1] will be req2 response
})

评论中提到的另一个选项是使用CombineLatest：

combineLatest(books, authors).subscribe(response => {
 ...
})

Answer 3

您可以使用以下内容：

combineLatest(
    observableAPI1,
    observableAPI2
)
    .pipe(take(1))
    .subscribe(([array1, array2]) => {
        const combinedArray = [...array1, ...array2];
    });

另外，我真的建议您使用类型。

希望这会有所帮助！
