示例1: encodeURI
(responseObserver: Observer<Response>) => {
const headers = req.headers.toJSON();
Object.keys(headers).map(function(key) {
if (headers[key].length > 1) {
throw `Header ${key} contains more than one value`;
}
headers[key] = headers[key][0];
});
let body;
// 1 stands for ContentType.JSON. Angular doesn't export ContentType
if (req.detectContentTypeFromBody() === 1) {
body = req.json();
} else {
body = this.getBodyParams(req.getBody());
}
const requestMethod = this.detectRequestMethod(req);
/**
* Request contains either encoded either decoded URL depended on the way
* parameters are passed to Http component. Even though XMLHttpRequest automatically
* converts unencoded URL, NativeHTTP requires it to be always encoded.
*/
const url = encodeURI(decodeURI(req.url)).replace('%252F', '%2F');
nativeHttp.setDataSerializer(
this.detectDataSerializerType(req),
);
nativeHttp[requestMethod](url, body, headers)
