## js中调用
```javascript
main:function () {
    var params = {
        "testData": "testData",
    };
    params.sign = this.getMd5Sign(params, "key");
    this.httpPost("http://test.com/testUrl", this.getFormData(params), function (responseText) {
        var result = {};
        try {
            result = JSON.parse(responseText);
        } catch (e) {
        }
    }, null, null, "multipart/form-data; boundary=testformdata");
},

httpPost: function (url, reqStr, successCB, errorCB, timeoutCB, ctype, reconnect) {
    var self = this;
    var xhr = cc.loader.getXMLHttpRequest();
    xhr.open("POST", url, true);
    if (typeof ctype == "undefined") {
        ctype = "text/plain";
    }
    xhr.setRequestHeader("Content-Type", ctype);
    xhr.onreadystatechange = function () {
        if (xhr.readyState == 4) {
            if (xhr.status >= 200 && xhr.status <= 207) {
                DC.retryConTimes = 0;
                cc.log(xhr.responseText);
                if (successCB && typeof successCB == "function") {
                    successCB(xhr.responseText);
                }
            } else {
                cc.log("http error state :" + xhr.status);
                DC.retryConTimes += 1;
                if (reconnect != false && DC.retryConTimes < DC.RETRY_CON_TIMES_LIME) {
                    setTimeout(function () {
                        self.httpPost(url, reqStr, successCB, errorCB, timeoutCB, ctype, reconnect);
                    }, 1000);
                } else {
                    DC.retryConTimes = 0;
                }
            }
        }
    };
    xhr.ontimeout = function (err) {
        if (timeoutCB && typeof timeoutCB == "function") {
            timeoutCB();
        }
    };
    xhr.onerror = function (err) {
        if (errorCB && typeof errorCB == "function") {
            errorCB();
        }
    };
    cc.log(url, reqStr);
    xhr.send(reqStr);
},

sortObjectKeys: function(params) {
    var keyArray = [];
    for (var k in params) {
        keyArray.push(k);
    }
    keyArray.sort();
    return keyArray;
},

getMd5Sign: function(params, openKey){
    var keyArray = this.sortObjectKeys(params);
    var signKey = '';
    for (var i = 0, li = keyArray.length; i < li; ++i) {
        signKey += keyArray[i] + "=" + params[keyArray[i]] + "&";
    }
    signKey += openKey;
    return CryptoJS.MD5(signKey).toString();
},

getFormData: function (data) {
    var boundary = '--testformdata';
    var endBoundary = boundary + '--';
    var result = "";
    var str = "?";
    for (var key in data) {
        result += boundary + '\r\n';
        result += 'Content-Disposition: form-data; name="' + key + '"' + '\r\n\r\n';
        result += data[key] + '\r\n';
    }
    result += endBoundary + '\r\n';

var array = this.strToUint8Array(result);
    return array.buffer;
},

strToUint8Array: function (str) {
    var buffer = [];
    var c;
    for (var i = 0, l = str.length; i < l; i++) {
        c = str.charCodeAt(i);
        if (c < 128) {
            buffer.push(c);
        } else if((c > 127) && (c < 2048)) {
            buffer.push((c >> 6) | 192);
            buffer.push((c & 63) | 128);
        } else {
            buffer.push((c >> 12) | 224);
            buffer.push(((c >> 6) & 63) | 128);
            buffer.push((c & 63) | 128);
        }
    }
    return new Uint8Array(buffer);
},
```
## OC中调用
```objective-c
+ (void)main {
    NSMutableDictionary *parms = [NSMutableDictionary dictionary];
    [parms setObject:@"testString" forKey:@"testString"];
    [parms setValue:@(6) forKey:@"testInt"];
    [self formPost:parms];
}

+ (void)formPost:(NSDictionary *)dicData {
    NSString *POST_BOUNDS = @"testformdata";

NSURL *url = [NSURL URLWithString:@"http://test.com/testUrl"];
    NSMutableString *bodyContent = [NSMutableString string];
    for(NSString *key in dicData.allKeys){
        id value = [dicData objectForKey:key];
        [bodyContent appendFormat:@"--%@\r\n",POST_BOUNDS];
        [bodyContent appendFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n",key];
        [bodyContent appendFormat:@"%@\r\n",value];
    }
    [bodyContent appendFormat:@"--%@--\r\n",POST_BOUNDS];
    NSData *bodyData=[bodyContent dataUsingEncoding:NSUTF8StringEncoding];

NSMutableURLRequest *request  = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30];
    [request addValue:[NSString stringWithFormat:@"multipart/form-data;boundary=%@",POST_BOUNDS] forHTTPHeaderField:@"Content-Type"];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:bodyData];

NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        dispatch_async(dispatch_get_main_queue(), ^{
        });
        NSDictionary *responseJSON = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
        NSInteger status = [responseJSON[@"status"] integerValue];
        if (status == 200) {
        }
    }];
    [task resume];
}
```
