Question

我正在尝试从特定API获取一些数据。如果我在API页面上进行测试运行，他们会将这个url作为响应返回给我，所以我可以从那里获取api数据：

（仅限分类摘要）

  getUploads(): Observable<UploadModel[]> {
    this.http.get(UPLOADS_ENDPOINT)
     .map((response: Response) => {

         // parse the json response here, and return an array of UploadModels

     });
  }

基本上意味着：1,2,3,4,5,6,7,8,9,10,11,12

我有一个类别数组，还有12个元素。

数组如下所示：

&categories=1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9%2C10%2C11%2C12"

从我的系统发出api请求，我调用的url必须具有与api测试相同的标准。但是，这就是我的URL的样子（只有类别片段）

dd($this->categories) outputs:

array:12 [▼
  0 => "1"
  1 => "2"
  2 => "3"
  3 => "4"
  4 => "5"
  5 => "6"
  6 => "7"
  7 => "8"
  8 => "9"
  9 => "10"
  10 => "11"
  11 => "12"
]

代码段：

&categories=%5B%221%22%2C%222%22%2C%223%22%2C%224%22%2C%225%22%2C%226%22%2C%227%22%2C%228%22%2C%229%22%2C%2210%22%2C%2211%22%2C%2212%22%5D

正如您所看到的，api测试的url片段比我的短得多。我认为那是因为编码？

我尝试先将数组转换为json并使用rawurlencode方法解决它。但这并没有解决我的问题。我需要以同样的方式“转换”网址，api会这样做。

有谁知道如何解决这个问题？

我找到了什么：

我发现这个片段几乎解决了我的问题

$categories = "&categories=" . rawurlencode(json_encode($this->categories));

结果如下：

$categories = "&categories=" . http_build_query($this->categories, null, "%2C", PHP_QUERY_RFC1738);

但是我真的不知道开头的ne 0来自哪里以及为什么每个数组元素之后总是有一个“=”字符

如果您检查变量，您会发现该网址编码与此问题无关：

var_dump(rawurldecode('categories=%5B%221%22%2C%222%22%2C%223%22%2C%224%22%2C%225%22%2C%226%22%2C%227%22%2C%228%22%2C%229%22%2C%2210%22%2C%2211%22%2C%2212%22%5D'));

string(63) "categories=["1","2","3","4","5","6","7","8","9","10","11","12"]"

请比较：

$categories = array('1', '2', '3');
var_dump(json_encode($categories));
var_dump(implode(',', $categories));

string(13) "["1","2","3"]"
string(5) "1,2,3"

http_build_query()在这里太过分了。你真的没有任何复杂的结构，只有一个字符串变量。
