我在woocommerce rest api中收到无效的签名错误。我也在使用ddo https://github.com/ddo/oauth-1.0a的oauth 1.0a脚本。我生成了两次api密钥。还删除了de oauth脚本中的版本参数，如woocommerce rest api文档中所请求的那样http://woothemes.github.io/woocommerce-rest-api-docs/

var oauth = OAuth({

var request_data = {

$http({

我刚注意到您的$ http方法获得的值request_data.get而不是request_data.method。我敢肯定你正在俯瞰大声笑
答案 1 :(得分：0)
使用Abdul Ahmad提供的服务修复了它：httpService.js
angular.module('httpService', []).factory('httpService', httpService);
httpService.$inject = ['$http', '$q'];
function httpService($http, $q) {
var methods = {
httpGet : 'GET',
httpPost : 'POST',
httpPut : 'PUT',
httpDelete : 'DELETE'
};
function baseGet(url) {
return $http.get(url).then(
function (result) {
return result.data;
},
function (result) {
return $q.reject(result);
}
);
}
function httpWithParams(url, method, params, data) {
return $http({
url: url,
method: method,
params: params,
data: data,
dataType: "json",
headers: {
"Content-Type": "application/json"
}
}).then(
function (result) {
return result.data;
},
function (result) {
return $q.reject(result);
}
);
}
function handleError(error) {
console.log(error);
}
return {
baseGet: baseGet,
httpWithParams: httpWithParams,
handleError: handleError,
methods: methods
}
}
然后用这个：
var oauth = OAuth({
consumer: {
public: 'ck_000',
secret: 'cs_000'
},
signature_method: 'HMAC-SHA1'
});
function getMyData() {
var request_data = {
url: 'http://test.dev/wc-api/v3/products',
method: 'get',
}
return returnData = httpService.httpWithParams(request_data.url, request_data.method, oauth.authorize(request_data))
.then(function(data) {
return data;
}, function(data) {
httpService.handleError(data);
return data;
});
}
