我希望将JS对象转换为x-www-form-urlencoded.如何在角度2中做到这一点?

I wish to convert a JS object into x-www-form-urlencoded. How can I achieve this in angular 2?

export class Compentency { competencies : number[]; } postData() { let array = [1, 2, 3]; thisppetencies = array; let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded' }); let options = new RequestOptions({ headers: headers, method: 'post' }); return this.http.post(this.postUrl, JSON.stringify(thisp), options) .map(res => res.json().datapetencies) .catch(this.handleError); }

推荐答案

application/x-www-form-urlencoded

转义控件名称和值.空格字符用 +'替换，然后按[RFC1738]第2.2节中的描述转义保留的字符:非字母数字字符替换为％HH'，一个百分号和两个十六进制数字，分别表示字符的ASCII码.换行符表示为"CR LF"对(即％0D％0A').控件名称/值以它们在文档中出现的顺序列出.名称与值之间用 ='分隔，名称/值对之间由'&'分隔.

Control names and values are escaped. Space characters are replaced by +', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A'). The control names/values are listed in the order they appear in the document. The name is separated from the value by=' and name/value pairs are separated from each other by `&'.

因此，您将需要转换JSON对象.我只是简单地遍历JSON和输出:encodeURIComponent(propertyKey)+"=" + encodeURIComponent(propertyValue)并将使用&标志.例如

Therefore you will need to transform your JSON object. I would simply iterate over the JSON and output: encodeURIComponent(propertyKey) + "=" + encodeURIComponent(propertyValue) and will combine them using the & sign. e.g.

var str = []; for (var key in obj) { if (obj.hasOwnProperty(key)) { str.push(encodeURIComponent(key) + "=" + encodeURIComponent(obj[key])) console.log(key + " -> " + obj[key]); } } return str.join("&");
