问题描述
我想提出几个Ajax请求的,同时迭代区的阵列(1至5)。我只能够在平均成功返回2请求,剩下的返回:
XMLHtt prequest无法加载https://api.nytimes.com/svc/politics/v3/us/legislative/congress/members/house/OR/2/current.json?api-key=xxxxxxx.
无访问控制允许来源标头的请求的资源present。原产地的http://本地主机:9001'。因此不允许访问
似乎没有图案到这些缺陷。即使使用相同的 _district
若干多次失败看似随机。
我的code:
VAR title_element,
title_render,
district_numbers = ['1','2','3','4','5'],
element_ids = ['ushd1','ushd2','ushd3','ushd4','ushd5'],
apiKey ='API密钥= XXXXXXXXXXX',
的baseUrl ='https://api.nytimes.com/svc/politics/v3/us/legislative/congress/members/house/OR/',
orUsHouseMembers,
FRAG; 对于(VAR I = 0,total_districts = district_numbers.length; I< total_districts;我++){
(函数(ⅰ){
VAR myUrl = +的baseUrl district_numbers [I] +'/current.json? + apiKey; $阿贾克斯({
网址:myUrl,
数据类型:JSON, 成功:功能(数据){
的console.log('\\ nSUCCESS:'+ myUrl);
title_element =的document.getElementById(element_ids [I]);
title_render = document.createTextNode(data.results [0]。名称+' - 区'+ data.results [0]。区);
title_element.appendChild(title_render);
}, 错误:功能(数据){
的console.log('\\ nFAIL:'+ myUrl);
}
})
})(一世);
}
我尝试添加访问控制允许来源:'*'
和所有常见的CORS的东西,但我不希望这是一个真正的CORS问题,因为失败是太间歇
时的东西在我的code不妥或可能的API?
Yes, instead of json
, change the AJAX's dataType
option to jsonp
:
dataType: 'jsonp'
In order to avoid of CORS issues when you only want to GET
data, use JSONP.
P.S:
Note that I tested it by myself in a small demo that I made using jsFiddle and it's working correctly, just take on account that it's now returns 403 (Forbidden)
- I assume because I should enter a valid api-key
, you provided a fake one (api-key=xxxxxxxxxxx
).
