render: function(){
console.log(this.state.search_results);
var renderedSearchResults = this.state.search_results.map((result) => {
console.log打印:
[{" id":" testGroup2"},{" id":" testGroup77777"},{" id& #34;:" testGroup1"},{" id":" testGroup3"}]
数据通过以下方式获得:
$.ajax({
url: this.props.routes.search,
contentType: 'application/json',
type: 'POST',
data: JSON.stringify(searchObj),
success: function(data){
console.log(data);
this.setState({search_results:data});
}.bind(this),
error: function(xhr, status,err){
console.error("/api/response", status, err.toString());
}.bind(this)
});```
通过:
def post(self):
"""
Makes a request to search for a specific
searchtype: Group
searchstring: ""
requestedfields: []
"""
search_type = self.json_data.get('searchtype', 'Group')
search_string = self.json_data.get('searchstring', '')
requestedfields = self.json_data.get('requestedfields', ['id'])
search_model = {
'Group': Group(),
'User': User()
}[search_type]
search_fields = {
'Group': ['id', 'tags'],
'User': ['username']
}[search_type]
# check if requestedfields contains valid fields
for field in requestedfields:
if field == 'id':
continue
value = search_model.default().get(field, None)
if value is None:
return self.set_status(400, "Model {0} does not have requested field {1}".format(search_type, field))
try:
search_results = search_model.search_items(search_string, search_fields, requestedfields)
except err:
return self.set_status(400, "Something went wrong")
self.set_status(200, "Success")
return self.write(tornado.escape.json_encode(search_results))
我真的很困惑this.state.search_results
不是一个我可以迭代的阵列,任何人都可以看到发生了什么?
我已尝试在成功功能中使用console.log(Object.prototype.toString.call(data));
,我得到:
[object String]

尝试以明确的方式设置json
数据类型,同时执行ajax请求:
$.ajax({
dataType: 'json',
//...
});
用于通过jQuery检测数据类型的Intelligent Guess
很可能是错误的结果。

找到我的答案,没有设置dataType:" json"在我的ajax请求中。
