Angular 解决跨域 配置代理 （适用于Angular2+）
1. 新建proxy.conf.json 文件 内容如下：
{
"/api": {
"target":
"http://124.77.3.162:8888",
"secure":
false,
"router" : {
"/v1/index":
"http://125.78.3.162:8888",
"/v1/finances":
"http://124.77.3.162:8888"
}
}
}
2. 在package.json文件中引入代理文件 修改scripts 的 start
{
"name":
"yqfx",
"version":
"0.0.0",
"license":
"MIT",
"angular-cli": {},
"scripts": {
"ng":
"ng",
"start":
"ng serve --sourcemap=false--host 0.0.0.0 --proxy-config proxy.conf.json",
"test":
"ng test",
"pree2e":
"webdriver-manager update --standalone false --gecko false",
"e2e":
"protractor"
},
"private":
true,
"dependencies": {
"@angular/common":
"^2.3.1",
"@angular/compiler":
"^2.3.1",
"@angular/core":
"^2.3.1",
"@angular/forms":
"^2.3.1",
"@angular/http":
"^2.3.1",
"@angular/platform-browser":
"^2.3.1",
"@angular/platform-browser-dynamic":
"^2.3.1",
"@angular/router":
"^3.3.1",
"core-js":
"^2.4.1",
"echarts-ng2":
"^1.4.1",
"primeng":
"1.1.4",
"rxjs":
"^5.0.1",
"ts-helpers":
"^1.1.1",
"zone.js":
"^0.7.2"
},
"devDependencies": {
"@angular/compiler-cli":
"^2.3.1",
"@types/echarts":
"0.0.9",
"@types/jasmine":
"2.5.38",
"@types/node":
"^6.0.42",
"angular-cli":
"1.0.0-beta.28.3",
"codelyzer":
"~2.0.0-beta.1",
"jasmine-core":
"2.5.2",
"jasmine-spec-reporter":
"2.5.0",
"karma":
"1.2.0",
"karma-chrome-launcher":
"^2.0.0",
"karma-cli":
"^1.0.1",
"karma-jasmine":
"^1.0.2",
"karma-remap-istanbul":
"^0.2.1",
"protractor":
"~4.0.13",
"ts-node":
"1.2.1",
"tslint":
"^4.3.0",
"typescript":
"~2.0.3"
}
}
3. 在service中地址写法如下，就能匹配到 http://124.77.3.162:8888/api/v1/finances
getConditionList(
id):
Promise<
any> {
let
headers =
new
Headers({
'Content-Type'
:
'application/json'
});
return
this.
http
.
get(
"/api/v1/finances/getCondition", {
headers:
headers })
.
toPromise()
.
then(
response
=> {
return
response.
json()
as
any;
})
.
catch(
this.
handleError);
}
