[英]Consuming restfull api and share the result to web page using Node.js
[英]Consuming API in javascript without using Node.js
我在Windows Phone 8应用中利用CamFind的API进行图像识别。 在他们的网站上,他们给出了如何与Node.js一起使用API的示例。但是,我正在编写PhoneGap Windows Phone应用程序,但没有此功能。
我只想使用简单的jquery / javascript来使用此API。
这是他们网站上提供的示例:
var Request = unirest.post("https://camfind.p.mashape.com/image_requests")
.headers({
"X-Mashape-Authorization": "Z**********************"
})
.send({
"image_request[locale]": "en_US",
"image_request[language]": "en",
"image_request[device_id]": "<image_request[device_id]>",
"image_request[latitude]": "35.8714220766008",
"image_request[longitude]": "14.3583203002251",
"image_request[altitude]": "27.912109375",
"focus[x]": "480",
"focus[y]": "640",
"image_request[image]": "/tmp/file.path"
})
.end(function (response) {
console.log(response);
});
这是我尝试使用jquery /'plain'javascript做同样的事情
$.ajax({
url: 'https://camfind.p.mashape.com/image_requests', // The URL to the API. You can get this by clicking on "Show CURL example" from an API profile
type: 'POST', // The HTTP Method
data: {
"image_request[locale]": "en_US",
"image_request[language]": "en",
"image_request[device_id]": "<image_request[device_id]>",
"image_request[latitude]": "35.8714220766008",
"image_request[longitude]": "14.3583203002251",
"image_request[altitude]": "27.912109375",
"focus[x]": "480",
"focus[y]": "640",
"image_request[image]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
}, // Additional parameters here
datatype: 'json',
success: function(data) { alert(JSON.stringify(data)); },
error: function(err) { alert(err); },
beforeSend: function(xhr) {
xhr.setRequestHeader("X-Mashape-Authorization", "Z**********************");
}
});
问题/问题:
谢谢!!
仅供参考,我正在使用的参考:
我知道这是一个古老的问题,但是在自己尝试解决此问题时偶然发现了这个问题,我认为我应该为将来回答。
问题是此行:
"image_request[image]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
它应该是:
"image_request[remote_image_url]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
因此完整的代码是:
$.ajax({
url: 'https://camfind.p.mashape.com/image_requests', // The URL to the API. You can get this by clicking on "Show CURL example" from an API profile
type: 'POST', // The HTTP Method
data: {
"image_request[locale]": "en_US",
"image_request[language]": "en",
"image_request[device_id]": "<image_request[device_id]>",
"image_request[latitude]": "35.8714220766008",
"image_request[longitude]": "14.3583203002251",
"image_request[altitude]": "27.912109375",
"focus[x]": "480",
"focus[y]": "640",
"image_request[remote_image_url]": "http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg"
}, // Additional parameters here
datatype: 'json',
success: function(data) { nowDoSomethingFun(data); },
error: function(err) { alert(err); },
beforeSend: function(xhr) {
xhr.setRequestHeader("X-Mashape-Key", "YOURKEY")
}
});
}
我不熟悉此API,但是您可以尝试格式化数据参数,如下所示:
data: {
image_request: {
locale: 'en_US',
language: 'en',
device_id: '<image_request[device_id]>',
latitude: '35.8714220766008',
longitude: '14.3583203002251',
altitude: '27.912109375',
image: 'http://exelens.com/blog/wp-content/uploads/2013/03/bmw-car-2013.jpg'
},
focus: {
x: '480',
y: '640'
}
}
