|

|
1141 | * // GET heroes whose name contains search term
|
1142 | * searchHeroes(term: string): observable<Hero[]>{

|
1144 | * const params = new HttpParams({fromString: 'name=term'});

|
1147 | * ```
|

|
1149 | * Alternatively, the parameter string can be used without invoking HttpParams
|
1150 | * by directly joining to the URL.
|
1151 | * ```
|
1152 | * this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});
|
1153 | * ```
|
1154 | *
|
1155 | *
|
1156 | * ### JSONP Example
|
1157 | * ```
|
1158 | * requestJsonp(url, callback = 'callback') {
|
1159 | * return this.httpClient.jsonp(this.heroesURL, callback);
|
1160 | * }
|
1161 | * ```

|
1163 | * ### PATCH Example
|
1164 | * ```
|
1165 | * // PATCH one of the heroes' name
|
